# Identifying Linear Functions

Standard

Linear Functions Organizer this does not include arithmetic sequences, which was earlier in the year, but I can refer back to our work with them to activate prior knowledge for this unit.  The next unit will be linear regression which will include correlation, describing scatterplots, finding regression equation with technology, using the equation to predict and finally introduction to residuals.

Students started with a pre-quiz similar to the one below.

Identify Linear Functions This is a booklet with a Frayer Model for our notes, a variety of math relations to identify as linear or not and a 2-minute reflection grid on the back.  Prior to beginning our notes, I gave them 1 minute to jot down anything they thought they knew about linear functions.  Then we pair-shared before sharing with the entire class.  Then we took our notes. (as a follow up the next day, I gave them 2 minutes to jot down all they could remember about linear functions as a small retrieval practice).

Our next task was created by cutting apart these relations and posting them around the room with a chart that asked if they agreed or disagreed with the example being a linear function.  Students received stickers to place on the chart as they visited each station.

I was fairly accurate in which ones I thought we’d have to use for discussion, but a couple really surprised me.  These are the 4 we discussed following the carousel activity.

I. y = 2x was the one I was not expecting.  When I asked if someone would share their thinking, one student said they thought x was an exponent.  Another shared they did see “the b” for y-intercept.  We looked at a table of values and graph to agree, and show the y-intercept was at the origin and indeed y = 2x was linear.

The other I failed to snap a picture of was graph K, a vertical line.  Yes, it’s linear, but not a function…two students got that one correct in this particular class.

Using the 2-minute reflection grid as our exit slip to see students thinking about the lesson, I was excited about some of their “I still have a question about…”

On the reflection grid, if they have no questions, nothing is confusing, I ask them to give me a caution…something to be careful or / watch for.  Several of these questions encompass multiple students.  Some of them I only needed to clarify what was said.  Its pretty clear I was not communicating very well on a few of the.  I hear my “expert blind spot” showing up…”Of course squared is not linear, we learned it was quadratic in our functions unit!”  But so many students on the pre-quiz used vertical line test as their reasoning for linear…we had some side conversations about this misconception…that it shows functions, but does not prove if its linear.

Some of the questions, I allowed other students explain their reasoning to help clarify their understanding.

I know I shouldn’t have favorites, but in this list…

Why can’t you multiply the numbers by each other?  We tried it.  Add 2 numbers that will make 18.  Create table of values, find rate of change, graph it.  Yep, that’s linear!  Multiply 2 numbers that will result in 18.  We created a table of values of their answers, found the rate of change and graphed them.  No, that’s not linear!

If an exponent is less than 1, can it be linear?  We will try it tomorrow as our bell ringer.  But I look forward to exploring their questions more!

I told them how excited I was about their questions and posted them on our “THINKING is not driven by answers, but by QUESTIONS” board.  One student had the biggest smile and as she said, Look!  I’m so proud, my question is on the board!  Something so simple, yet, my hopes are that it will encourage her to ask more questions.

One student asked me, but isn’t it disrespectful to ask questions and interrupt the lesson?  Nooooooo.  I love when you ask purposeful, curious questions you wonder about!  Finally, a break-through to get them to start asking and wondering more…

# Personal Reflection 3-2-1 #MTBoSchallenge

Standard

Our school district will begin using a new Certified Evaluation Plan this year.  The CEP has 2 major components: Professional Practice and Student Growth.  As part of the Professional Practices, each teacher is asked to consider various pieces of evidence and complete a self reflection which eventually leads to their individual Professional Growth Plan.

I will be completing my self reflection this upcoming week, which has had me wondering this weekend, what are my goals for this school year?

3 things I want to learn, incorporate, practice:
I have read about Flipped Classrooms since before I began blogging.  Watched a couple webinars, read several blog posts, articles.  Its always been of interest, but I just didn’t have take the time.  I have recently begun my first Flipped Unit in my Algebra 2s.  It nothing major, I have linked to videos readily available on You Tube, but have quickly learned if students are accessing on their school accounts, YouTube is blocked.  So I am now looking for possible places to host my own videos (eventually, I want to use my own).

My interpretation is either introduction or skills needed for problem solving which in turn allows students time in class for real application of math.  Following each video, I include 3-5 questions of the big ideas/takeaways for student self-assessment of the video.  When I begin creating my own, I intend to keep them around the 4 minute range, continue including self-assess questions.  For student who dont have access, they can come to my classroom prior to school/class and complete, but they are not allowed to participate in the days activities until they’ve completed the video or shown understanding to me.

Lesson Study – I have read some posts, been involved in a few informal twitter chats, even discussed the process with colleagues at TMC14.  I have located some resources through our PD360 I intend to utilize, but now, I have to find a friend and convince them its worthwhile to journey with me.

Talking Points -I want to ensure that every student feels like they can share their ideas and be heard.  Talking Points is the key for me developing this culture of learning.  I look forward to learning more, sharing with my students and implementing this as a classroom norm.  Here is a place to start.  Severval MtBoS have implemented them as the school year began.  I will share my experiences soon!

2 things I want to continue improving:
Literacy in Math Class- Whether reading, interpretting/deciphering informational text, writing, reflecting on their learning, verbally communicating or strategies to help studentsconnect vocabulary to prior knowledge…communication is a key skill they can use elsewhere.  Last spring, I participated in a webinar based on the book Vocabulary Their Way.  I sincerely feel providing students with similar tools will enhance their learning across all discilpines.  I plan to use some of the structures I’ve learned from Kagan resources and develop some of my own activities for student interaction with peers.

Standards Based Grading – about 5 years ago, I became very interested in aspects of Standards Based Grading.  It just made sense.  I had read, researched, even implemented some successful approaches.  I have heard through the grapevine, theres a possile push for our district to move this direction.  Even though it has not come from an official administrator, I’ve heard teacher conversations outside of vertical meetings that sounds like it may be on it’s way.  I am uber excited.  I have been looking for some good quality resources to share, should the time arise.  @mpershan shared a link this morning for a couple of good resources.  Scroll down to Garry Chu SBG.  Although, I think the Jeff Harding’s video following it gives a fun analogy to show how ridiculous some of our grading practices are-supporting Why we should consider SBG, then Mr. Chu shares some great ideas on How to implement.  I look forward to getting to move on this journey again (finally).

1 thing that’s Imperative in My Planning…
Standards of Mathematical Practices Yes, I am very familiar with them, yet I have not been so intentional in my planning and inclusion of them.  I had a major a-ha last year that I had missed the boat when first becoming familiar with CCSS.  The SMP should have been the anchoring foundation prior to transitioning to CCSS.  As I plan this year, I will be intentional and very explicit in providing students opportunities to use them.  But also in asking students to reflect on their uses of them.  I look forward to reading NCTM’s Principles to Actions, hoping it will guide me in this goal.  Another resource I plan to revisit is Making Thinking Visible.  I read it a couple of years ago, but feel it provides quality routines to enhance student learning that support the SMP.

This week my nephews are in town.  They love playing outdoors, have crazy fun imaginations and are loads of laughter.  My 10 year counts down the days each year until they arrive at gramma’s!  Its more exciting than end of school countdown.

On Tuesday I was brainstorming with mom and looked into geocaching.  I had never been, only heard it mentioned a few times and needed to learn how it worked.  So I went to geocaching.com registered an account, downloaded the app and yesterday, we set off on our first adventure.

Though most were the grab and go – the kids enjoyed it and were super excited when we found a cache filled with kids party favor swag.  Only problem, we had to scavenger the car to find some trade items…a creative venture in itself.

Each find has a log where you date and sign to prove you were there.  There are hints, clues on the app if you have trouble locating it.  For example, one clue was Australia.  We looked around trying to connect something with that and finally “down-under.”  Sure enough, the cache was underneath the landmark.

We found 10 on our first day and learned some great tips.  We even saw a robin’s egg that had fallen from the nest, a double rainbow as we drove from place to place, played on a playground and visited the gravesite of their great grandparents as one cache was near the cemetary.

Some very clever hiding techniques!  One cache was so tiny, we thought it was only a magnet that had lost its container somehow!  It took a while to roll the log back small enough to place in it again!

Some where along the way, someone asked if I could spell supercalifragilisticexpealidocious (sp?).  My oldest nephew said, well, it shouldn’t be that difficult if you just break it apart.  True.  My response, most words are the same way.  For example, geocache.  Geo is earth, cache, a hiding place.  Which led me to geometry…geo, earth; metry, to measure.  I went on to explain how people wanted to measure distances, areas of land, patterns they noticed in the earth, so they created geometry.

I explained how people noticed patterns with their shadows at different times of day.  I asked, when is your shadow longest, when is it shortest?  Without a hesitation, someone popped up, when the sun is on the horizon, your shadow is longest, when the sun is above you, your shadow is shortest.  I asked how do you know?  One said well, we learned that in science, but if you think about it, it just makes sense.

Again, I am convinced we force too many ideas on our students rather than just letting them think about it and develop their own sense of reasoning.

On our earlier finds, I allowed the kids to look at the GPS readings on the app.  They had to decide which direction to go -are we too close or too far north, and how far to walk.  We needed to moved west once and they could use the compass corectly, but I asked, what if we didnt have it pointing out the directions for us?  I explained how the sun sat to the west and each time after that, they immediately gauged direction based on the sun.

When I returned home after dark, I tweeted of our adventures.  In a convo,

So, now I am curious…how can/are teachers using geocaching as a context for learning?

If so many of our ‘at-risk’ students struggle with literacy, can we as teachers be smarter in how we present vocabulary, reading choices in class and providing better tools for students to develop their understanding of concepts and terms?

We are getting ready to take a look at polygons, interior/exterior angle sums…in the past, I have always listed names of polygons based on number of sides…but is that really correct? Afterall, polygon is many-angles…  Should I change and reference the list names based on number of angles?  Doesn’t that make more sense when we look at the history of the word?

Triangle, quadrilateral, pentagon, hexagon, heptagon, octagon, nonagon, decagon, 11-gon, dodecagon…the only one I see in the list that actually references sides is quadrilateral…  I remember seeing the term quadrangle in one of my daughter’s elementary assignments a few years back…that makes more sense, right?

So then that lead me to diagonal…dia, something to do with “-gonal” angles… maybe connectiong angles?  And there’s diameter…dia, something, to do with “meter” a measurement.  And diagram…dia, something to do with “gram” something written…

From etymonline.com

diagonal (adj.) 1540s (implied in diagonally), from Middle French diagonal, from Latin diagonalis, from diagonus “slanting line,” from Greek diagonios “from angle to angle,” from dia-“across” (see dia-) + gonia “angle,” related to gony “knee” (see knee (n.)). As a noun, from 1570s.

diameter (n.) late 14c., from Old French diametre, from Latin diametrus, from Greek diametros (gramme) “diagonal of a circle,” from dia- “across, through” (see dia-) + metron “a measure” (see meter (n.2)).

diagram (n.) 1610s, from French diagramme, from Latin diagramma, from Greek diagramma”geometric figure, that which is marked out by lines,” from diagraphein “mark out by lines, delineate,” from dia- “across, out” (see dia-) + graphein “write, mark, draw” (see -graphy). The verb is 1840, from the noun.

So dia-is across, -gonal is angle, segment connecting angles…

I believe I will change how I present this to my students this year, which will allow them to connect this “new knowledge” to future concepts based on the history of the roots…

# Unit Organizer Update & Feedback Only Grading

Standard

Its been a good, very good, no, great start to the year.  Almost scary how smoothly it has begun.  But I will take it and be happy. Very happy.  I always have amazing kids.  They make me smile.  They make me think.  They make me love what I do.

I have read about comments only grading multiple times.  A colleague shared more research as part of an action research project last spring.  Reading and chatting Wilham’s Embedded Formative Assessment this summer convinced me I needed to give up grades on student work and offer feedback only.  So far, so good.  When I pass target quizzes back, I allow some time for students to mark on their organizers where they consider they are based on feedback I have offered.  I will definitely be sharing updates.

I shared a unit organizer here a couple of weeks ago.  It’s gone well, though I knew I wasn’t satisfied with it.  But this afternoon, Crazy Math Teacher Lady shared this

My thoughts are to modify my booklet style organizer to include this on the inside.  I appreciated the graph for each target.  This goes right along with some research from #efamath chat this summer.  It reminds me of something similar I had seen on @druinok’s block a while back.  I like how Lisa has a place for students to record multiple assessments.  This is a great layout!

I plan on keeping a vocabulary knowledge survey on the front as suggested by Math = Love.  Here is a sample of mine

And keeping the assessment grid on the back for personal reflection…

I re-intoduced an old assignment from a few years ago in my first units…students were asked to write their own unit assessment using our learning targets.  Most seemed to put good effort in to interpretting what each was asking.  Offering written feedback gave me a chance to address some of their misconceptions, mostly notational issues in diagrams they had included or clarifying some vocabulary.

My intentions were for them to go back through their INBs, notes, target quizzes.  A couple of times in class, I fielded specific questions they had.  Based on what I observed, I believe it was a useful task.

I am looking forward to my new organizers!  Thanks to Lisa, Sarah & @druinok for sharing such awesome ideas!

# INB Unit Organizer

Standard

I wanted to create a unit organizer than encompassed several aspects but would also be narrowed to one page, fiting in to the INB.  Here’s a list of what I wanted:

vocabulary
unit overview/schedule
learning targets
record of assignments
track their own assessments/learning
place to record questions/big ideas
opportunity for end of unit reflection

Here is what I arrived at for a first attempt, copied front to back and folded in half, this is the order students will see the booklet.

The vocabulary pre-assess was a great tool.  I saw this idea over at Math = Love earlier in the summer.  It went so well. It only took students a couple of minutes to self-assess their vocabulary knowledge.  As I walked around, I was able to see several terms had 3s & 4s.  We compiled a list of our 1s & 2s words.  I explained, as they learned a word or gained better understanding, they should go back and put a +.  Before the end of class, students were asking if they could go ahead and update their chart.

If possible, maybe completemthis part a day before beginning a unit, in order to make needed adjustments based on student responses.

I included the correlated CCSS # for each target.  Eventually, these may be beneficial when looking online for a resource on a specific standard.

I am not fully satisfied with this chart yet. Assignments made for specific targets can be listed, a note if completed (stamp) and place to monitor their assessment for each.  A second line has been included in case RTI/enrichment is needed.

Finally, the back side has a place to record reflection.  Ideally, I would have them complete the reflection at least 2 days prior to unit assessment, allowing to address any needs the following day, prior to assessment.

As always, this is a work i  progress, suggestions and ideas are welcomed!

# Happy Birthday #Made4Math !!! Formative Assessmemt Reminder Cards

Standard

First, just let me say a big THANK YOU to @druinok for beginning #made4math and to all of the generous folks who have openingly shared their classroom ideas, lessons, tips over the past year.  I was overwhelmed with how quickly it took off!  Still, today, I am amazed at the generosity of this community.  I have learned so much and my classroom was definitelh impacted by your awesome ideas!

My share for today was initially a result of a convo with @rachelrosales and @druinok, brainstorming ways to organize reminders for the numerous formative assessment techniques…something simple, at your finger tips.

I loved @druinok’s post today and her Student Engagement Flipchart.  Very.Nice.  It will definitely be on my to-do list for a future project.  However, I am choosing to share a similar idea, just a bit different format.  I cut down index cards to fit sports card pages… pack of 10 for \$1.  I am able to display up to 90 of these reminders ranging from formative assessment techniques to various strategies for student engagement, reflection, etc.

Front side of card has title, with some information…

Back side of cards has description, suggestions, reminders…

I have placed the pages in a small 3 ring binder which can easily hold more pages.  Currently, I am trying to include summaries/reminders of techniques I have used or see being easily modified for math class.

Looking forward to learning and sharing more FA techniques with my amazing PLN!!!
