Let me remind you that I teach 1st grade. One common characteristic of these little guys is that they always seem to be wiggling and chatting. Rather than beat my head against a wall trying to stop it, I try to embrace it :)
Click each image below for a free copy of the problem solving routine poster. This is a great way to add movement and repetition into math. I also like it because the routine forces my students to stop and listen to the word problem rather than just writing an answer.
For the bats, students chose a handful of bats out of a baggie and then wrote how many of each color. They were also given problems like " I have 7 bats. 3 are orange and the rest are purple." The color coded bats helped them to solve for the unknown addend.
The bugs were dropped onto the table and students then counted how many were "bellies up". This was one way we practiced decomposing a number. We saw that there were many ways to make the number 13 for example like in this picture (9 bellies down + 4 bellies up = 13). Students recorded on paper.
I found a little bowling set and knew it would make the perfect math station (teacher nerd alert). Students rolled the ball and counted how many pins they knocked down on the first try. Then, they rolled again and found the sum of the two rolls. My kids were begging to play this game again all week long!
Lastly, here is one of my newest products that I introduced to my class a few weeks ago. I bought mini clothespins from Michaels (super adorable). What I love most about these Rocking Addition & Subtraction clip cards is the variety of strategy mats. I want my students able to show their work. Part-Part-Whole Mats, Ten Frames, Number Lines, and music note manipulatives help students solve each problem.
The clip cards are also color coded based on the numbers used with works great for differentiation. Our current standards have us working with addition to 10 (blue) and subtraction from 10 (green). I also included problems to 20 (pink and orange) so we can use it all year long.
Rocking Addition and Subtraction will be 25 % this week (October 5th- 11th).
