Your students will never tire of playing these fun BUMP games. There are separate gameboards for doubles to 12 and for doubles to 18. Each game has twelve colour and twelve black and white gameboards. The colour gameboards have wonderful clip art and backgrounds and will last for many years if laminated. If you don't have access to a colour printer, it would be fun to have your students colour the gameboards when they have finished their work. These games are ideal for pairs of students to work independently. An instruction page is included.
