Part-Whole Relationships
Learning Objectives: Understand the size of the fractional part is relative to the size of the whole; Apply the part-whole relationship using real-life objects before moving to fractional numbers
Pizza Party Problem
Introductory Discussion: Using this image, begin the introductory lesson allowing students to explore cutting up whole pizzas to share equally among all students. You may want to give them paper and pencils so they can draw out their ideas.
Number sense is important, so include in your discussion the difference between the 3 whole pizzas and the number of slices that are created. This will give students an opportunity to discover the relationships between wholes and parts. Possible discussion questions for student discourse:

Identifying the Part and the Whole
Now that students have explored the difference between wholes and parts of the whole, they will practice identifying the whole group versus part of the group.
Part 1: Show students various sets of groups allowing them to determine how many are in the whole group and identify a part of the set by name and how many. Using individual white boards, have students answer and check for understanding before moving on to stations. Part 2: Part-Whole Stations - in small groups or partners, allow the students to rotate through stations of various sets. Students will be able to decide how they group the items and identify the different parts. Download the student recording sheet for the stations.

Assessment: Module 1 - Creating Sets
After completing the first two parts of this module, your students should have an understanding of the part-whole relationship. To assess their mastery, a short 5-question assessment is posted below for your students. There is an online version (which can be posted to a Google Classroom or other learning management system) or a printable version. If you would like to assess your students using the Draw It feature on Nearpod, the images have been included to use for each question.
