Lesson Plans: Go Math Grade 5 Chapter 3 - Add & Subtract Decimals
Product Description
Students add and subtract decimals using several models. Of particular importance is the place-value model represented with base-ten blocks. As students solve addition problems with base-ten blocks where the flat is equal to one, the long is equal to one-tenth and the small cube is equal to one-hundredth, they are led to see that when adding decimals, the hundredths can be combined with hundredths, the tenths with tenths, and so on. They see that similar reasoning can be applied to subtraction. These experiences help students to look for and make use of structure as they make sense of place-value algorithms for adding and subtracting decimals.

The lessons accompany and are based on Go Math textbook (5th Grade), with rich content and higher level questions. The lessons can stand on their own even if the instructors does not use Go Math, where alternative practice exercises can be utilized.
