These worksheets are designed to help students develop their understanding of subtraction using the part-part-whole model. By completing the diagrams and writing corresponding number sentences, students will strengthen their conceptual understanding of how a whole is made up of two parts, fostering essential number sense and subtraction skills.

How to Complete:

Students will solve each subtraction problem by subtracting the part from the whole and writing the difference in the remaining ‘part’ section. After completing the diagram, students will write a matching subtraction number sentence below.

Additional Tips:

1. Encourage students to use manipulatives such as hundreds charts or number lines if they need extra support when subtracting the numbers.
2. Discuss strategies with students for solving the problems, such as breaking the smaller number into tens and ones to simplify subtracting.

Extension Ideas:

1. Fact Family: Challenge advanced students to use the completed number sentence to create fact families.
2. Partner Problems: Have students create their own part-part-whole problems to share with their peers.
