Teaching combinations of 10  a fun way to teach kids about all the different addition combinations that equal 10. This activity also provides a great introduction to the commutative property of addition, which says that when two numbers are added, the sum is the same regardless of the order of the addends. #handsonmath  Gift of Curiosity

First Grade Parade  “Make 10” tray to build houses  scrapbook paper roof to a little tray {Dollar Tree}. Then my kids get to pick two different color popsicle sticks out of the box. I keep about 4 different colors inside. They can only use 10 sticks to build their houses and show me how many different ways they can construct it using two different colors. Then they have to record their work in their Math Journals.
Some great math ideas here, from Cara Carroll @ The First Grade Parade
