The mini-lessons
- Plan the calculation before pressing keys
- Negative numbers and subtraction
- Brackets and order of operations
- Fractions and exact answers
- Powers and roots
- Standard form on a calculator
- Rounding and interpreting the display

- Calculator traps and Mistake Detective
Inside every pack
What each part of the page is for
Confidence check
Pupils tick how a topic feels before they start, and again at the end. There are no marks, so it's an honest picture of where they are.
Short mini-lessons
Each topic is split into small steps. Every mini-lesson opens with one big idea and a short, plain-English explanation.
Visuals for every idea
Diagrams such as a formula 'rule machine' or a place-value picture show the maths, so pupils can see it as well as read it.
Worked examples
Every method is modelled step by step before pupils try it, with each stage labelled so they can follow it on their own.
Scaffolded practice
Questions start with prompts (what do you need to find, follow the example, check it makes sense) and gradually ask for more independence.
Spot the trap
Common mistakes are named before pupils make them, and Mistake Detective questions ask them to find and fix errors.
Pause and think
Short 'explain it in your own words' prompts check that pupils understand why the maths works, not just how.
Teacher Pack with answers
Every pack comes with a Teacher Pack: all the answers, plus reteach cards saying what to watch for, what to say, and what to try if a pupil is still stuck.

Number 17 · Year 8
Multiplying and Dividing Decimals
Multiplying by 10, 100 or 1 000 makes a number bigger, so the digits move left. Dividing makes it smaller, so the digits move right. The decimal point stays still. Count the zeros to know how many places.

Number 18 · Year 8
Multiplying Decimals by Whole Numbers
Multiplying a decimal by a whole number still means equal groups. 0.4 × 3 is three groups of 0.4. Estimate first, multiply, then make sure the answer is a sensible size.
