Students learn that adding means putting two groups together and counting them all — building the very first and most important skill in math with a hands-on picture of every sum.
Students will be able to…
If you have 3 red apples and 2 green apples, how many apples do you have in all? What does it mean to “add”?
Project this and set two groups. Watch the dots come together — count them all to find the sum.
