I put the students in pairs. One student wrote numbers 1-10 on pieces of paper and the other student placed 10 ants along the top of the page (I drew circles for the students to have a starting spot for their ants)
Here is how the activity worked:
Student A would place ants in the first two boxes to make an addition sentence ___+___.
Student B would then solve the addition problem and place the number card in the last square.
They took turns putting the ants in the box and then solving the problem. They really enjoyed this and were focused for about 15 minutes! This gave me time to float the room and make sure they were understanding the concept of addition!
