- Sort 3-D objects and 2-D Shapes and explains the sorting rule
- Copy given composite 2-D shapes and 3-d objects
- Compare 2-D shapes to parts of 3-D objects in the environment
Before I introduced the choices as a class we played with the iPad app Explain Everything. Each child created their own 2D shape book from items from around the classroom. Here's a sample created by one of my students.
The second option was to use the iPad/iPod camera to take pictures of geometric shapes found in our classroom and then to use those pictures to create a "shape" poster using the free Pic Collage app. Again several students choose this option too.
