- 620
- 450
- 890
Read the explanation
Compare the hundreds with five - fewer than five hundreds means less than five hundred.

Game teaching guide

What children will practise

Recognise numbers in the 8 times table, tell exact division from division with a remainder (indicator ค 1.1 ป.3/7), compare three-digit numbers with 500, and sort units for small or large quantities.

What's in the worksheet

4 sorting questions with 2 boxes each - 16 and 40 are in the 8 times table; 18 and 42 are not - 199 and 450 are less than 500; 620 and 890 are more - Millilitre and millimetre are for small things; litre and kilometre for large things - 24 ÷ 6 and 40 ÷ 8 divide exactly; 25 ÷ 6 and 41 ÷ 8 leave a remainder

How to use it in class

Use after the 8 times table and division with remainders, about 6 minutes, solo or pairs. - In the division question, point to 24 ÷ 6 and 25 ÷ 6: one more in the starting number leaves a remainder of 1 - For the 8 times table, leave the table on the board the first time through - For units, teach that the prefix milli- means small and kilo- means large - Play it linked to the class to record results in the mark book

Common sticking points

- Putting 18 or 42 in the 8 times table because they are even and close to 16 and 40. Count up in eights to check - Putting 41 ÷ 8 under exact because 40 ÷ 8 is exact. Show 8 × 5 = 40 with 1 left over - Thinking litre is for small things because a 1-litre bottle is easy to hold. Compare with millilitres for medicine drops or a teaspoon
