Comments or Notes

2019 COS correlation:

1.5). Relate counting to addition and subtraction. Example: counting on 2 to add 2.

1.7). Explain that the equal sign means “the same as”. Determine whether equations involving addition and subtraction are true or false.
Example: determining which of the following equations are true and which are false: 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2
