Build a stronger understanding of the relationship between parts and wholes with this interactive digital addition and subtraction activity! Students use part-part-whole diagrams to determine the missing number and connect each model to a corresponding equation.

Students analyze each diagram, determine whether a part or whole is missing, and move the correct number into place. They then write an equation to represent the relationship shown in the model.

What's Included:

• Interactive missing number activities
• Part-part-whole diagrams
• Addition and subtraction practice
• Movable numbers to complete each model
• Opportunities to write corresponding equations
• Google Slides version
• PowerPoint version
• Seesaw links

Skills Practiced:

Students practice finding missing parts and missing wholes, representing part-part-whole relationships, and using addition and subtraction to solve for unknown numbers.

Use these activities on your Smartboard or projector for whole-group instruction, or assign them to students for independent practice, math centers, small groups, intervention, or review.

This digital activity is a great way to help students move beyond simply solving equations and develop a deeper understanding of how addition and subtraction work together.
