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

How to Complete:

Students will solve each addition problem by adding the two ‘parts’ together and writing the total in the ‘whole’ section. After completing the diagram, students will write a matching addition number sentence below.

Additional Tips:

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

Extension Ideas:

1. Reverse It: Challenge advanced students to reverse the process by giving them the whole number and asking them to break it into two possible ‘parts’.
2. Partner Problems: Have students create their own part-part-whole problems to share with their peers.

This worksheet is an excellent resource to give your students hands-on practise with the part-part-whole addition strategy.
