Premium Combined Means | Maths Codebreaker | Answers Included

PREMIUM RESOURCE - available to purchase; this is not a free download.

Calculate weighted means and find missing group or remaining-group means.

This Premium paid resource contains one complete A4 pupil worksheet with 22 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 6 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. 7 numbers have a mean of 15. A further number, 24, is added. Find the new mean. Give your answer to 2 d.p.
2. 6 pupils have a mean score of 6; 10 other pupils have a mean score of 10. Find the combined mean. Give your answer to 2 d.p.
3. 11 scores total 126. The first 4 have mean 14. Find the mean of the remaining 7. Give your answer to 2 d.p.

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.

This resource belongs to a completed 100-topic Maths Codebreakers range. Halloween codebreaker resources are also available. A mixed-topic revision codebreaker range is coming soon. These other ranges are separate resources and are not included in this download.
