Part-Whole Model Activity: Finding Missing Parts

Develop your students’ mastery of number bonds and arithmetic with this hands-on Part-Whole Model Activity.

This resource is designed to strengthen children’s understanding of how numbers are composed and decomposed, helping them build confidence in their addition skills.

What’s Included:

• Printable Part-Whole Models: A series of models featuring varying combinations for students to solve.
• Activity Design: Each model is framed for easy cutting, making it a perfect addition to interactive maths journals or workbooks.
• Addition and Subtration Practice: Students are tasked with finding the missing part in each model and writing the corresponding addition/subtraction number sentence underneath.
• Extension Opportunities: Students can be challenged to explore inverse operations - how many number sentences can they write for each model?

Why You’ll Love It:

• Investigation Opportunities: Encourages children to explore different number sentences to match their models.
• Versatile Implementation: Ideal for independent morning work, guided maths centres, or as a follow-up assessment after whole-class instruction.
• Low Prep: Simply print, distribute to your students, and let them get to work.
