The FREE Brick Math Lesson of the Month for December 2024  comes from Brick Math’s Subtraction. To get this lesson, click here, and you’ll also get a new free Brick Math lesson every month after that. ​

This lesson teaches students how to subtract within 20 and uses a strategy called “ten-frames,” which helps students see the numbers as they relate to the number 10. Ten-frames are a wonderful way to introduce the base ten system early on.

The lesson starts with pages from the Teacher Edition of Brick Math Subtraction. Modeling with bricks, the teacher shows the concept of subtracting 6 minus 4, and then 12 minus 8. In each case, the models are built on ten-frames, which help to show the numbers as part of the base ten system. The lesson uses important subtraction vocabulary words like subtrahend and difference.

The second half of the Lesson of the Month comes from the Student workbook for Brick Math Subtraction. These are the pages students will use as they follow the teacher’s lesson. In these pages, the students respond to questions and draw the brick models as they build them. This is all part of the Brick Math learning method, which starts with building models, then drawing the models, and then explaining the math in words. It’s a proven method that gets real results with students.
