About this resource
Add three numbers, decide whether the total is odd or even, then write another three-addend equation with the same sum.
- Rows of three-addend equations
- Parity column for each computed sum
- Space to create an equivalent three-addend equation
Curriculum reference — England: Inspect values before claiming an addition-facts range; parity is a separate component. Three one-digit addends are explicit in England Year2; parity is an additional topic. Use Grade2 addition facts and odd/even concepts only where sums stay within the actual worksheet range. Selected skills only; reference stage is not an overall reading age, complete curriculum coverage, or an automatic recommendation for every learner.

Teaching tips & learning objectives
Learning objectives
- Find the sum of three one-digit addends
- Construct a different three-addend expression with an equivalent total
Teaching tips
- After solving, let learners change one addend up and another down by the same amount to generate a new equivalent equation.
Skills covered
- Multi-addend computation — Combine three quantities accurately
- Equivalent-expression reasoning — Preserve a total while changing addends
