Although I'm not signed up for this group's challenge, it caught my imagination and brought back memories of my teaching days.
The challenge was to create a bird.
I remembered doing something similar with the children in my classes using tangrams.
You can find these puzzles quite easily on the internet and can download free PDF templates if you and your children wanted to try them out.
Not only can you make birds, there are many other animals and shapes you can create. I know that the children in my classes enjoyed doing them. So over to you.
