About this lesson
By the end of this lesson your child can add, subtract, multiply and divide with negative numbers, and work out which way to move before they start. Most children can tell you that −5 is a negative number. What trips them up is that −5 is smaller than −4, and that taking away a negative moves you the other way.
Topics covered:
- Numbers below zero, comparing and ordering them, including decimals like −2.5 and −2.05
- Adding and subtracting a positive, where the answer crosses zero, such as 6 − 7 and −5 + 8
- Adding and subtracting a negative, where two signs sit next to each other, such as 5 + −3 and 5 − −3
- Multiplying and dividing, with one rule that covers both, same signs give a positive and different signs give a negative
- Mixed questions and order of operations, including −4² against (−4)² and calculations like −5 + 6 × −2
Your child works through this lesson on any screen. They click to reveal each step of a worked example, try the practice questions on paper, then click to check their own answer.
How it's structured:
- Each unit opens with a worked example your child clicks through one line at a time, then practice questions colour-coded easy, medium and hard
- 90 questions in total, each with a click-to-reveal answer and a reveal-all option
- A final 20-question mixed challenge pulling from all 5 units, the way negative numbers actually show up on an exam paper
Zero is the landmark most worksheets walk straight past. Counting back eight places from 5 in one go is where children lose track and end up one out. This lesson teaches your child to stop at zero on the way, so 5 − 8 becomes five steps to zero and three more after it. The number line makes that journey in two jumps on screen, and pauses at zero to ask how much further there is to go.
Four interactive tools your child can play with. A thermometer, a sea level, a bank balance and a lift, all sitting beside the same number line, so below zero means something before it means arithmetic. A guided number line that walks a sum one place at a time and shows the two signs merging into one. A second guided line for the harder sums where a minus meets a minus. And a sign grid where your child can hide the answers, decide whether the result is positive or negative, and then check.
Use this if:
- Your child is in Year 4 to Year 11 and thinks −5 is bigger than −4
- You're preparing for the 11+, where temperature and depth questions come up most years
- Your child is doing GCSE Foundation and loses marks on the signs rather than the method
- You want a resource your child can check their own work with, not one more thing on your to-do list

Aadam, the tutor has a lovely mannerism and has made my daughter feel at ease. He explains the question in a way that she understands and is patient with her. She has already seen the results at school from his help and has gone up two GCSE grades in a short period of time.P. Flower · December 2024

FAQs
How do I access the lesson?
You'll get an email with your lesson link as soon as payment goes through. Click it to open the lesson in any browser, no login and no app to install.
How does the marking work?
There's no typing answers into a box. Your child works it out on paper, then clicks to reveal the correct answer and checks their own work. Full working is shown too, not just the final answer, so mistakes are easy to spot.
Does it work on a phone or tablet?
It works best on a tablet or laptop, where there's more room to read the examples and questions. It'll open on a phone too, but the text and diagrams can feel quite small on a smaller screen.
Can I use the lesson more than once?
Yes. There's no limit on how many times you open the link, so it's there for revision right up to the exam.
What if I lose the link or don't get the email?
