Find All Possible Parts – Part–Part–Whole Practice Worksheet

What It Is:
A structured part–part–whole worksheet where students list all possible pairs of parts that can make each whole number. Each box shows a whole (5, 6, 7, 8, 10, 11) with two blank “part” spaces for students to fill in every valid number combination.
Why Use It:
This worksheet strengthens students’ understanding of number relationships and reinforces addition concepts. By identifying all combinations that form a whole, learners build fluency in decomposing numbers—an essential foundation for mental math and arithmetic strategies.
How to Use It:
• Review how numbers can be broken into two parts using simple examples.
• Have students fill in all possible pairs that create the target whole number.
• Encourage students to check their work by adding each pair to verify accuracy.
• Use during math centers, small-group instruction, homework, or skill-building practice.
• Assign this worksheet after the “Part–Part–Whole Word Problems” worksheet to expand students’ understanding through number exploration.
Grade Level Suitability:
Designed for Grades 1–2.
• Grade 1: Introduces basic number decomposition in simple form.
• Grade 2: Strengthens number sense, addition fluency, and logical reasoning.
Target Users:
Ideal for elementary teachers, math interventionists, parents, homeschool educators, and students who are practicing number combinations and decomposing whole numbers.
