Awesome session Mary and Alex! Thank you. Thank you. Thank you.
The session focused on their experiences with Grade 10 Applied students ( Canada). The entire course is activity based which allows students to not miss out on big ideas as they would in a traditional unit by unit aligned course.
Students have repeated opportunities to experience big ideas. The tasks are rich with multiple entry points and different approaches to solving. It’s a collaborative environment with accountable talk. There are fewer disciplinary issues with increased engagement.
Each 6 weeks a mini – exam over entire course up to that point takes place. Questions are in context and tied to activities they have completed.
We began with beads and pennies on our desks and this task… Cole has 2 smarties and 3 juju bed for $.18 while Noah has 4 smarties and 2 juju be for $.20. They shared that systems are presented this way – no algebraic forms- for the first several weeks of class. I, personally, can see how effective this strategy could be.
The next activity shared was Sum of Squares (he doesn’t refer to it as Pythagoras Theorem, yet – or did he say ever?)
Students are asked to cut all squares from side length 1 to side length 26. Each square is labeled with side length, perimeter, area. Then they build with them.
Basically students explore and eventually they focus on triangles formed with question, are there 3 you cannot make a triangle with? Which combinations form different types of triangles. Begin looking at 3-4-5 triangle families, similar triangles (Kate suggested dilations here), discuss opposite side and adjacent sides, then give them a TRIG table and allow them to figure it out.
Compare side lengths with perimeter, or side length with areas. The possibilities of math concepts are endless.
We ended the day with Card Tossing by collecting data, then using rates to make some predictions.
Video of Alex & Nathan picture below is only a screenshot.
@AlexOverwijk downed by @nathankraft 75 to 72
Each person in the room completed several trials of tossing our cards for 20 seconds. We found our average rate of success, then determined who we thought might beat King Card Tosser.
Alex asked us to predict how long they needed to toss if he gave Nathan a 35 (?) card advantage so it would be super close and exciting. Our prediction 38 seconds about 75 cards. Many ways of making the predictions were possible. Not to shabby, huh?
This task was fun, exciting, engaging. Definitely on the to-do list.
This approach is definitely something I would like to consider, if administration will allow it!
