New year, new FREE Brick Math Lesson of the Month!
For January 2020, the lesson is from Subtraction Using LEGO® Bricks Teacher and Student Editions. The lesson teaches students about subtracting within 20, and utilizes the modeling technique of ten-frames to help students begin to understand the power of our number system that is based on 10.
The ten-frame is built with a 2x5 configuration of bricks. Two easy ways to build a ten-frame are to use either a 2x4 and a 1x2 brick, or to use a 2x3 and a 2x2 brick. Just make sure those bricks are the same color, so the 2x5 configuration of the ten-frame is all one color.
Then the subtraction is modeled on top of the ten-frame. There are two examples in this lesson to demonstrate subtraction using this method: the first one shows 6 - 4 = 2; the second one, which uses two ten-frames to model, shows 12 - 8 = 4.
Try this lesson with your students who are learning the concept of subtraction. You'll only need a few LEGO® or compatible bricks to model both problems, and you'll help your students "see the math"!
