FREE Median and Range Problems | Maths Codebreaker | Answers Included

FREE DOWNLOAD - no purchase required.

Find missing data values using medians and ranges.

This FREE resource contains one complete A4 pupil worksheet with 21 questions and a matching answer page with workings, plus a product-family guide. Pupils solve the maths, match answers to letters in the code grid and decode the hidden words.

Difficulty: Level 5 of 10 within this range (1 is easiest; 10 is most demanding). These levels are a guide to relative challenge, not GCSE grades.

Three questions from this worksheet:
1. The highest test score is 36 and the range of the scores is 33. Find the lowest score.
2. Here are four test scores in ascending order: 1, 3, x, 30. The median score is 5. Find x.
3. Here are five test scores in ascending order: 7, 16, x, 38, 41. The median score is 17. Find x.

Use for focused practice, consolidation, homework or a lesson activity after teaching the method. Print the pupil page for learners and retain the answer page for checking. Follow the rounding and unit instructions on the sheet.
