Creating Sets and Comparing Numbers

We've been working on identifying and creating sets of numbers 1-15. I gave the students a Christmas light cut out. We drew a card from a deck and put that many "lights" on our Christmas tree. The students worked together to create the set and then we counted to check our work. Once students were able to do this quickly, we drew a card and then used the more/less spinner to create a set more/less than the number we drew. Once again the students worked together to figure it out and then we counted to check.

 

Then students went back to their sets and worked with their partner, to create sets of decorations on a Christmas tree from the number card drawn. Then we used the more/less spinner to create sets more/less than the number drawn.

We also played a comparing numbers game, where each partner drew a number card and then they used math talk to compare numbers (9 is less than 13. 13 is more than 9.). Then they laid their cards on the more/less mat and then spun the more/less spinner to determine who won the cards. Once all the cards were played the partners counted their cards and then spun the more/less spinner to determine the winner.
