Teaching Notes

Use the worked example and teaching sequence below to explain the reasoning before independent practice.

Before You Begin

Recognize straight sides and corners.

Teaching Steps for Parents and Teachers

Count sides and vertices.
Check defining attributes such as equal sides, right angles, or parallel sides.
Use attributes, not color, size, or orientation, to classify.

Worked Examples

A polygon has five sides. What is its name?

Count each side once.
A five-sided polygon is a pentagon.

Answer: Pentagon

Common Mistakes and How to Help

Turning a shape does not change its shape family.

Would your classification still hold if the shape were rotated?

Questions to Check Understanding

Would your classification still hold if the shape were rotated?
What in the numbers or diagram supports your answer?

Practice Advice

Work through the example together. Ask the learner to explain the first two problems, then try three independently. Review the first incorrect step before assigning more practice.

Next Practice

Use New Numbers to practice the same skill with different values.
If the learner needs help, return to the example and model each step before trying again.
