We've been working on the concept of +1 in math. One of the hands-on approaches to developing this concept is through staircases.
We talk about starting with 1, and then what happens when we add 1 to that. We repeat the process until we get to 10. The + symbol has been new learning for many of the kids and so has the idea of building a staircase. While some kids can just see the idea behind the staircase and build it, others need to be taught how to do this.
This is a great concept to work on at home. Have your child build a staircase out of Cheerios. Start with 1 and then work through "+1" until they get to 10. For advanced kids, have them try writing the +1 number partners as they go. 4+1, 5+1, 6+1.
Happy counting and adding!
