Place value and estimation

A set of powerpoints, powerpoint templates and worksheets.
They go with my rewrite of the Place value and estimation section in first number chapter of the Edexcel Higher textbook.

It contains:
Estimate an answer involving decimals. (No “basic” estimation questions )
Use a calculation to find the answers to another (number facts)
(2.3)6 = 148 correct to 3 significant figures, find (0.23)6. No questions like 2019 Sum P1 Q8b
Estimation with squares and square roots
Number estimation problems
Book: Not enough questions.

There are
5 powerpoints
7 worksheets
8 Powerpoint templates of the questions on the powerpoints so no time is spent copying out.

The whole first chapter has been completed to take account of the type of questions found in the new 9-1 GCSE.

The estimation theme is carried on into later chapters.
