2D Shapes: Real or Not?

Three wide rows make up this 1st grade page, each headed by one shape name in a teal pill and followed by four drawings in white circles. The child reads the name and circles every drawing that really is that shape, which can be more than one. On the sheet shown the triangle row holds three true triangles, all turned or stretched, and one shape with a curved side. The rectangle row has one upright rectangle beside a slanted four-sided shape, a rectangle with a gap in its outline and a tall shape with rounded corners. The square row pairs a small square and a tilted square with an unclosed square and a leaning rhombus.

This face turns the naming task around. Instead of choosing a word for a drawing, the child holds the word fixed and tests each drawing against it, which is how first graders learn to tell defining attributes from ones that do not matter: closed or open, straight sides or curved, square corners or not. Size and turning never decide anything here, and the rows are built so that they cannot. The near misses are the teaching: an outline with a small gap, a rectangle whose corners have been rounded off, a square pushed over into a rhombus.

One sheet, three rows, twelve drawings. The number of true shapes changes from row to row, so a child cannot simply circle one per row and stop; ask them to say why each rejected drawing fails before they move on. Use it after the base page, where every drawing was a real shape, and before the riddles face, which describes the same attributes in words instead of showing them.
