Product Description

The Why Behind the Worksheet:

This no-prep, hands-on introductory activity has students make their own discovery about the value and meaning of pi. Students will measure various circular objects (any circular object will do!) to find the circumference and diameter, and then compute that ratio.

Computing the ratio of their large and small circles alike should lead to the "aha!" that circumference divided by the diameter equals pi, regardless of the size of the circle selected.

Works Best For:

This is great for the beginning of a unit on exploring the properties of circles and the concept of pi. This also helps build better conceptual understanding of why the various circle formulas work they way they do.

Supplies You'll Need:

The only supplies needed are any circular objects from around the classroom, and a tape measure for each small group.

Learner Supports:

Language and math supports are included to help students with developing math vocabulary and English language fluency.

• Vocabulary for diameter, circumference, and ratio (teachers can even have students cut apart the vocabulary section and do a quick match-up activity)
• Place value visual and vocabulary listed
• Sentence frames to support student responses for analyzing their data
• Vocabulary checklist for forming a written response

Connections to Other Learning:

• Centimeter units in the metric system
• Rounding to the nearest hundredth decimal place
• Fraction vocabulary (numerator, denominator)
• Division vocabulary (dividend, divisor, quotient, ___ divided by ____)
