Read, model, calculate, check

Ask learners to identify what is known and what the question asks. A drawing, timeline or equation can make the relationship visible before they calculate. Check the answer against the original story and keep its unit.

The ready-made English downloads include practice alone or a separate answer key. The generator keeps the same questions in the preview and PDF, and a saved link reproduces the selected set.

Learning objective

What this activity builds

Add whole-number and fraction parts while preserving the measured unit.

Worked example

One board is 2 3/4 metres long and another is 1 2/3 metres long. What is their total length?

2 3/4 + 1 2/3 = 3 + 9/12 + 8/12 = 4 5/12 metres.

The fractional parts make 17/12, which includes one additional whole metre.

Teaching notes

Make the practice count

  • Keep whole parts visible while finding a common denominator.
