Missing Addends - Year 4

Build confident equation-solving with a complete Year 4 mathematics unit focused on missing addends and unknown values. Students learn that the equal sign shows the same value on both sides, use part-part-whole relationships and inverse operations to find unknowns, and check answers by substitution.

Explicit teaching, hands-on games, differentiated worksheets and assessment provide a cohesive progression from fact families to balanced equations, word problems and multi-part challenges.
