We started our addition and subtraction unit by reading Christmas Angel from Clifford's Puppy Days series. Then I passed around a bag of Christmas decoration and each student took one. Then I told addition and subtraction stories about decorating a Christmas tree. We worked on making two sets and then joining them together or making a whole and separating them.
Here's a peek at our math journal!
We also used a Snowman mat and buttons to model addition and subtraction stories. Students did more of the story telling that day and took turns modeling on the elmo the stories as worked them together.
