Three free sample questions from our long multiplication course. Every question comes with a full explanation, and hints that guide without giving the answer away.
A shop orders 20 boxes of folders. Each box contains 32 folders. How many folders is that altogether?
Hannah buys 21 packets of stickers for a party. Each packet costs £13. What is the total cost?
Harry is stocking a market stall with crates of oranges. He has 47 crates with 36 oranges in each crate. How many oranges is that altogether?
This is the exact interactive worked example your child sees in SEAGReady. Step through it and watch the method build up.
A school orders 20 packs of exercise books. Each pack contains 34 books.
How many exercise books is that altogether?
34 × 20
Multiplying by 20 is the same as multiplying by 2, then by 10
Step 1 of 3
A school orders 20 packs of exercise books. Each pack contains 34 books.
How many exercise books is that altogether?
The school orders 680 exercise books altogether.
The key insight: Multiplying by 20 is just multiplying by 2 and adding a zero!
Common mix-up: 34 × 20 = 68. Forgetting to multiply by 10 after multiplying by 2.
These are the misconceptions we see most often in long multiplication, including the ones our practice questions are specifically designed to catch.
Struggling with long multiplication? The real gap is often in one of these earlier topics.
SEAGReady finds the exact step where your child gets stuck, teaches it with worked examples like the one above, and brings it back for review so it sticks.
