Flat and solid shapes

Telling flat shapes, like a drawn square, from solid shapes you could hold, like a block or a ball, and naming both kinds.

How to help

Ask: could I pick it up and hold it, or is it flat like a drawing? Solid shapes are drawn looking thick. A cube is solid; a square is flat.

Watch for: Calling a cube a square, or a ball a circle. Thinking a picture of a block is flat because it's on paper. Choosing by color or size instead of whether it could be held.

At home: Collect a box, a can, a ball and a sheet of paper. Sort them into solid and flat, then trace around the box to draw a flat shape.
