Each SEAG paper has 28 maths questions. Questions 29 to 50 are multiple choice with five possible answers, and questions 51 to 56 need a short written answer. With 56 questions in 60 minutes across English and maths, that is about a minute per question.
SEAGReady breaks find fraction of an amount into 2 steps, taught in order so each skill builds on the last.
Find unit fractions (1/n) of whole number amounts by dividing the amount by the denominator
Find non-unit fractions (a/b where a>1) of amounts using the divide-then-multiply procedure
Try three free questions from our find fraction of an amount course. They start easy and get harder, so you can see where your child's confidence runs out. If they manage the last one without a hint, this topic is probably secure. If not, the steps above show where to start.
Jack's 20 marbles are split into 4 equal groups. The highlighted group is 1/4. How many marbles is that?
Mark walked 36 kilometres during a charity hike. He completed 5/6 of the walk before lunch. How many kilometres did he walk before lunch?
Emily has £84 in her savings account. She takes out 1/7 to buy a present, then puts 1/4 of what she took out into her piggy bank. How much money goes into her piggy bank?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
Ruby has 24 sweets to share equally among 4 friends at her birthday party.
How many sweets does each friend get? This is the same as finding 1/4 of 24.
1/4 of 24
Finding a fraction 'of' an amount means dividing
Step 1 of 3
Ruby has 24 sweets to share equally among 4 friends at her birthday party.
How many sweets does each friend get? This is the same as finding 1/4 of 24.
Each friend gets 6 sweets. So 1/4 of 24 is 6.
The key insight: Finding a unit fraction of an amount is just dividing by the bottom number!
Common mix-up: 1/4 of 24 = 24 ÷ 1 = 24. Divide by the denominator (bottom), not the numerator (top).
These are the misconceptions we see most often in find fraction of an amount, including the ones our practice questions are specifically designed to catch.
Struggling with find fraction of an amount? The real gap is often in one of these earlier topics.
