Odd and even numbers
Answers are for parents and teachers.
1
Pick some things at home: spoons, socks, buttons (1 to 10). Make pairs. Say odd or even. Try five different amounts.
The child makes pairs. If one is left over the number is odd. If none is left over it is even.
2
Walk up 10 stairs (or take 10 big steps). Say ‘odd’ on step 1, ‘even’ on step 2, and keep going. Which steps are even?
Steps 2, 4, 6, 8 and 10 are even. The words take turns: odd, even, odd, even.
3
Is each number odd or even? Say each one.
| 3 | 8 | 6 | 1 |
3 is odd, 8 is even, 6 is even, 1 is odd.
4
The answer is 5. Write two different questions that have 5 as the answer.
For example: How many dots are on this dice? Which number comes after 4? What is the next odd number after 3?
5
Put up to 10 beans on a plate. Estimate how many, then count. Is your number odd or even?
The count is right, the estimate is close, and the odd or even word agrees with the pairs.
