Adding Numbers in Kindergarten

Before Winter Break we started unit 3, in our Math Expressions curriculum.  In this unit we continue our work with adding numbers together.  We will continue working on seeing the numbers 6-10 as "5 plus another number".  We'll also continue our work in place value, seeing the teen numbers as "10 plus another number".  Now, we'll be looking at different ways to break numbers apart, seeing the partners that numbers have.

For example, in the picture below, we see two partners in the number 7.  We can see that 5 and 2 are number partners that make 7.

Today we focused on the number 6.  Since dice lend themselves well to this activity, we took turns rolling the die.  The rolled number was the first number partner, we had to figure out which number would be the number partner after the break-apart-stick.  Then we built our number arrangement and said the equation out loud.  The kids put their break-apart-sticks in their backpacks to take home.  This would be a great activity to do at the kitchen table.  Kids could use Cheerios, marshmallows, pennies, or anything else as their math manipulatives. 

Happy rolling and adding!
