About the Mathematics in This Unit

Dear Family,

Our class is starting the year with a mathematics unit called Coins, Number Strings, and Story Problems. This unit lays the groundwork for the mathematics we do all year. We will focus on counting by 1s and by groups of 5 and 10, identifying and recognizing coins and their values, using what we know to add and subtract numbers, developing fluency with the addition and subtraction facts, and understanding and solving a variety of story problems that involve addition and subtraction.

Throughout the unit, students work toward the following goals.

Benchmarks/Goals Examples

Which one is the dime?

What's the name of the other coin?

A quarter and a dime.

“A quarter is worth 25 cents.”
