August 2021 FREE Brick Math Lesson of the Month -- Adding Decimals

​The August 2021 Lesson of the Month comes from the Decimals book. To get the August 2021 Lesson of the Month, plus a new lesson each month, click here. 

​For the first time, we’re showing you Part 2 of a lesson, or “Show What You Know.” This comes after the teacher has demonstrated the skill in Part 1 of the lesson (“Show Them How”), with the students working along with their own bricks. In Part 2, the teacher poses a problem for the students to work out while the teacher observes and coaches.

​In Part 1, students have learned how to model decimals in a 100 x 100-stud decimal grid.  In Part 2, students are first asked to model 0.42 in a decimal grid with bricks. Next, they are asked to try modeling any combination of studs that adds up to 0.30. In the Decimals book, the example illustrated is 0.14 + 0.16. The 100 x 100 decimal grid is a very useful tool to explain the concept of decimals to the one-hundredth place.

​Author of the Brick Math series, Dr. Shirley Disseler, demonstrates how to teach this decimal addition lesson in a one-minute Brick Math video, which is also part of the August 2021 Lesson of the Month. Watching the videos on the website really helps a teacher or parent understand how to guide a student through the Brick Math curriculum.
