Examples of Warmup Activity
- Number boxes - give a number have children do a variety of operations on it (could be laminated papers that are used over and the number changed)
- Number pyramids - each number is the sum of the two numbers below it. Can you make a pyramid that has 100 at the top?
- Matchstick problems - how can you remove four sticks to give exactly 4 equilateral triangles?
- Gameshow question (Monty Hall)
We talked extensively about responses to problems. We discussed which stage each answer suggested. Most of the answers were easy to interpret. Some trouble arose (for me at least) in distinguishing the higher stages. The lower stages were easy, except for the ones where I didn't notice a "6" was missing.
Then we talked (in groups) about the ALIM resources we were given a few months ago. It was an interesting discussion and I got some good ideas of things that worked from other teachers. One example was making number bonds using the double sided counters and a bag/container. Shaking them up and then seeing how many of each.
The last thing we did was to discuss different ways to get children to use imaging on stage three. Some of the ideas we came up with were: using the abacus to count by twos (don't let the kids see, they need to count in their heads based on the sound). You could also roll a dice and say: I have 5. How many more dots do I need to make 10?
As usual, this was a pretty helpful session and hopefully in the future I'll be able to write about the things I've tried in the classroom.
