About the Mathematics in This Unit

Dear Family,

Our class is starting the year with a mathematics unit called Building Numbers and Solving Story Problems from the Investigations Curriculum. This unit is an introduction to mathematical ideas such as counting and comparing quantities, and addition and subtraction. Throughout this unit, students will be working toward the following goals:

Benchmarks/Goals	Examples
Understand that you can count on/back to add/subtract 1 or 2	“To solve 5 + 2, I can think 5 … 6, 7.” “To solve 5 − 2, I can think 5 … 4, 3.”
Fluency with the + 1, + 2, − 1, − 2 facts	5 + 1 = 7 − 1 = 6 + 2 = 8 − 2 =
Determine which of two pairs of numbers to 10 is greater	d “8 and 6 is more than 7 and 6 because 14 is more than 13.”
