Two digit addition in kindergarten? Well, yes!

What do you do when you have 10 kids in your kindergarten class that have mastered addition and subtraction facts to 18 and yet some students have never seen a plus or minus sign and know limited numbers? Well, you differentiate! However, being 28 places at once is not easy. I still need to teach the basics of number concept to 10 too.

I made a video for these students that need to start 2 digit addition. I needed to make sure they understand the concept place value first. Then I can go from there by teaching them to add 2 two-digit numbers and eventually regrouping.

Here is the video. Nothing fancy and easy to make. I referenced the straws that we use in our calendar math as well to tie in the "old" piece with the "new"piece. This is made with an ipevo camera and quicktime. Don't be intimidated. They are super easy and fun to make and you can use them year after year.
