Description
What It Is:
A visual math worksheet that helps students understand how numbers combine to make 20. Using tens-frame style dot models, learners break apart 20 into two parts and write matching addition and subtraction facts.

How to Use It:
• Count the dots in each tens frame to determine the two parts of 20.
• Write the part–part–whole numbers in the boxes provided.
• Complete the matching addition and subtraction equations.
• Use as a warm-up activity, math center task, partner work, or homework.
Grade Suitability:
Best suited for Grades 1–2.
• Students learning to decompose numbers to 20.
• Learners practicing addition and subtraction fact families.
Target Users:
Teachers, homeschool parents, and students building foundational addition and subtraction skills.
