About this resource

Round the factors to the nearest ten to estimate each of ten products, then calculate the exact answers and compare.

  • Ten multiplication equations
  • Nearest-ten rounding and estimate space for each equation
  • Actual-product space for checking the estimate

Curriculum reference — England: England Year 4 estimation provides a partial skill connection; check factor size before fixing the recommended level. OCR confirms two-digit by two-digit multiplication; Ontario Grade5 algorithms, with rounding as a supporting strategy. Two-digit multipliers and rounding checks fit Year5 rather than Year4. Selected skills only; reference stage is not an overall reading age, complete curriculum coverage, or an automatic recommendation for every learner.
