What's the Difference?
This was a "2 a.m. can't sleep" idea that I am so excited about ...I call them subtraction sliders! I used pipe cleaners, beads, washers and a metal ring to hold it all together. The point is for students to slide the beads to subtract. Let's say the number sentence is 15-4 then the students would find the "15" slider and slide 4 away to find the difference. Easy to make... takes a little time, but easy. I am excited for students to have this hands-on visual to use for subtracting. I am going to have a parent volunteer make a few more for me to use with my class.
