Description
What It Is:
A number-facts worksheet that helps students decompose a number and write its related addition and subtraction facts. Students use the “number house” model to break apart the given number and record two addition and two subtraction equations.
Why Use It:
This worksheet strengthens number sense by helping students understand part–whole relationships and fact families. It reinforces addition and subtraction fluency, supports mental math development, and builds a deeper understanding of how numbers work together.
How to Use It:
• Have students choose two parts that make the target number.
• Write both addition facts using the decomposed numbers.
• Write both subtraction facts using the same number pair.
• Use as a warm-up, small-group activity, independent practice, or homework.
Grade Suitability:
Best suited for:
• Kindergarten–Grade 2 students learning number bonds and fact families
• Grade 3 students reviewing addition and subtraction relationships
Target Users:
Teachers, parents, tutors, and students practicing addition/subtraction fact fluency and number decomposition.
