How to teach it

Compare a square and a rectangle. Point out that both have four right angles, so a square also belongs to the rectangle family.

Example to work through together

Use the model below as you explain the example. Have your student point to the quantities as you discuss them.

Square → rectangle → quadrilateral

Each name in this chain includes the properties needed by the next family. A square has four right angles, which makes it a rectangle. A rectangle has four straight sides and is closed, which makes it a quadrilateral.

Ask your student

Why is every square a rectangle?

If your student needs help

If the student rejects a tilted square, rotate the paper and check its sides and angles together.

Choosing and using the worksheet

This sheet reuses three fixed activities: two explanations and one drawing. New numbers does not create different questions; the same tasks remain. It supports selected quadrilateral-family reasoning, not a complete shape-classification unit. Rhombus classification and sorting a varied collection of pictured shapes are not assessed here.

Make a practice set

Select the worksheet, answer key, or both. When both are selected, the answer key prints after the questions. Keep it separate if you want your student to work independently.

Print materials

After your student finishes

Ask the child to give every correct family name for a square, then explain how their own drawing differs from a rectangle.
