Students have been working with number lines to make sure they understand that a negative gets smaller the further away from zero. This can be confusing when the number is large and has a negative sign. I remind them about owing their mom money and they quickly get it. They have also been working with opposites, and absolute value. In this activity I threw it all in.
For this activity I used a lot of bottle caps. Wrote the integer on them with a sharpie marker. I dumped the pile in floor and then had groups come work for 3 minute rotations. I loved the discussions they were having.
