For parents: how to use this lesson
You don't need to know this topic yourself. The lesson explains each step on screen, the way Mr Euclid, our Head of Maths, likes it: one tidy step at a time. Every answer is marked straight away with a worked explanation, so you never have to mark anything.
- Read what your child will learn together.
- Press Start the lesson below and sit with your child for the teaching and the worked examples (about 19 minutes).
- Let them do the practice on their own. They choose Getting started, On track or Challenge – start on On track and move up after a few right in a row.
- Finish with the exit ticket and the talk question: “How can knowing 10% help you find 15%?”
- Later that day or the next day: the homework (20 minutes), then a practice test.
Watch out for
- Dividing by the percentage (25% of 80 = 80 ÷ 25). Start from 10% or 50% and build up.
- Subtracting the percentage number (20% of 60 = 40). Remember 20% means 20 out of every 100.
Miss Hypatia's tip for home: Work out sale prices in a shop or online: what is 20% off?
What your child will learn
We are learning to find percentages of amounts.
Success looks like
- I can find 50%, 25% and 10%.
- I can build other percentages from 10% and 5%.
- I can check my answer makes sense.
Key words
- per cent (%)
- out of 100
- percentage
- an amount written as a number out of 100
- equivalent
- the same value: 25% = 1/4 = 0.25
What to have ready
- Paper and a pencil
- This page on a computer, tablet or phone
- For the hands-on part: Use a 100 square: shade 10%, 25% and 35% and write each as a fraction and a decimal. No squared paper? Draw a 10 by 10 grid.
