Dear Family,
Our class is starting a new unit in mathematics called How Many of Each? How Many in All? We will be working on developing strategies for adding and subtracting numbers by counting on or back, solving problems that involve adding more than two numbers, and finding many different combinations for the same number. We will also begin to work with tens and ones as we represent the teen numbers as a group of ten plus a group of ones. Throughout this unit, we will be thinking about how to use equations to record our work. We will also be counting larger quantities and reading and writing larger numbers.
Throughout this unit, students will be working toward the following goals:
Benchmark/Goals | Examples |
---|---|
Understand that you can count on to add two numbers. And, you can count back to subtract. |
6 + 3 = _______________
9 − 3 = _______________
|
Understand that a group of 10 ones is the same as 1 ten and that all of the teen numbers are made up of 1 ten and a number of ones. |
