I’m a teaching student, and I want to share this idea from last year’s placement.
Prior to the start of the session, the reception teacher placed a cube, cuboid, cone, and a sphere into a bag called her feely bag. In the lesson, the children had to describe a solid by feeling it and saying, “This has a point; there’s a circle at the bottom”, etc. The other children had to guess the solid from these descriptions.
A feely bag is naturally a really useful resource which can be used in other subjects too such as science.
