They begin at the concrete level in Lesson 6, using play money to review the different coin values from Grade 1. Lesson 7 builds upon this foundation as students find the total value of a group of coins in the context of simple addition and subtraction word problem types with the result unknown (2.MD.8). Similarly, in Lesson 8, students apply their understanding of place value strategies and skip-counting to find the total value of a group of bills within $100, again in the context of addition and subtraction word problems. In Lessons 9 and 10, different combinations of coins are manipulated to make the same total value, for example, “Estella has 75¢ to buy a yo-yo. How many different ways could she pay for it?” Students focus on making change from one dollar in Lessons 11 and 12, using the understanding that $1 has the same value as 100 pennies. In the final lesson of Topic B, students solve two-step addition and subtraction word problems with abstract drawings and equations with the unknown in various positions. 15:T606,
