This is a file that can display up to 10 timers counting down from whatever time you require. The timers can have a student or a group name next to it and each timer can be paused and started independently of the others. I use it in my school for tracking 15 mins of reading time amongst other things. It is a flash based file so needs to be run in IE or flash player

Checklist of content at each tier.

Nice Christmas lesson. Can be done under timed conditions for points for completing pictures or just as a challenge. I give bonus points for anyone who manages to make the square out of their pieces or another picture. Any tangram set can be used. Card or paper are fine but Ive made my own tangram sets out of carpet tiles so they can be nice and big and solid. For differentiation I tend to draw round whatever tangram set im using so it becomes a jigsaw outline. Or sometimes I just tell them the position of two pieces depending on the group. Merry Christmas!
