We did an activity yesterday that I found really interactive and the students LOVED it. "This is the best game I have played in math yet!" was from one of my students who does not particularly love math.
It was called "Shake Those Disks". The students are working with number bonds for 6. They worked in partners and had 6 red/white disks. They would shake them in a cup and record the partners on their bar graph. They had so much fun and really learned the partners for 6!
