Lesson Plan Title : Comparing Eggs

Age Range: Grade 6 through grade 8 (Middle School)

Overview and Purpose: In this math activity, students weigh and measure different sizes of eggs to find information about the eggs weight and circumference and draw conclusions about each size.

Objective: The student will be able to compare the different sizes of the eggs to see the differences in weight and circumference.


One box of each size of eggs

Food scale-one per group

Measuring tape

Teacher created worksheet


Hold up one of each kind of egg that is found in the grocery store. Ask the students to describe what differences they see. Explain that in this activity they are going to compare the different sizes and weights of different boxes of eggs. Divide the class into small groups and have each group weigh and measure two of each size egg. As they are working, have them complete the worksheet. When they are finished, come back together as a class and discuss their findings

Sample questions

1. What is the average weight of all the eggs you measured?

2. What is the difference in circumference between the largest and the smallest egg?

3. Is this statement true or false: The smaller the circumference of the egg, the less it weighs? Why or why not?

Wrap Up:

This activity could also be completed by giving each group of students a dozen of the same size eggs. They could weigh and measure each egg to see what, if any, variance there is within the defined size.
