How to teach it

Place the center at the vertex and align one ray with zero. Follow the scale that begins at that zero.

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.

Estimate, align, read, check.

First decide whether the opening is smaller than, equal to, or larger than a right angle. Then place the tool carefully and compare the reading with that estimate.

Ask your student

Which scale starts at the ray we lined up?

If your student needs help

If the student reads the other scale, compare the result with whether the angle is acute or obtuse.

Choosing and using the worksheet

Each sheet reuses two measurement tasks and two drawing tasks. The original bank uses 30°, 45°, 60°, 90°, 120°, 135°, and 150°. Values differ within each pair, but a particular angle or an acute/obtuse balance is not guaranteed.

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 how the child chose the correct scale and checked the opening against a right angle.
