The 6th grade Florida state standards states that students should understand the ratio of Pi. This Pumpkin Themed Math Lab allows students to create and test their own hypothesis on the ratio of Pi. The lesson starts with a bell work vocabulary review. Then students review a Florida Standards Assessment (FSA) question and create a hypothesis about the ratio of Pi. In small groups, students will measure the dimensions of a pumpkin and explore different mathematical ratios. Students will come to a conclusion about the ratio of pi based on their calculated ratios. The math investigation takes about 45 minutes, perfect for one class period. The integration of Bell work, Vocabulary Review, Hand-on small group work, and Conclusion make this a perfect lesson for an OBSERVATION!!

What is included:

1. Pumpkin Pi Lab Template- One-page, ready-to-print student template

2. Teacher instructions for implementation

3. Answer Key

What you need:

1. One or more PUMPKINS (You could also have students bring in their Jack-O-Lanterns for this investigation! Or you could buy several pumpkins—one for each small group)

2. Five tape measures--One for each group (Like this one: https://amzn.to/2ZkBZdI)

3. Five calculators- One for each group (Like this one: https://amzn.to/2nmQs7J)

to see state-specific standards (only available in the US).
Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”
