Help children strengthen their understanding of inverse operations and number relationships with this set of differentiated Year 3 Missing Number Problems worksheets.
These engaging worksheets encourage pupils to think mathematically by identifying the missing value in addition and subtraction calculations. Children must apply their understanding of inverse operations to work backwards and solve each problem.
The worksheets are structured to gradually increase in difficulty and are ideal for homework, classwork, interventions, or revision.
This resource includes three differentiated worksheets so teachers can easily match work to pupils’ ability levels.
What's included
• 3 differentiated worksheets
• Triangles – lower ability
• Circles – middle ability
• Squares – higher ability
• 18 questions per worksheet
• Full answer sheets included
Each worksheet asks children to work out the missing number in calculations such as:
27 + □ = 45
□ + 28 = 63
83 − □ = 52
Pupils are encouraged to use inverse operations to check their answers and develop strong number sense. Y3_Topic_Missing_Numbers_547-549
Skills Covered
• Using inverse operations
• Solving missing number equations
• Understanding the relationship between addition and subtraction
• Strengthening mental arithmetic strategies
