Question 1
There were 430 people at a concert. 323 people left early. How many people stayed?
🎵- 117
- 113
- 753

Hint: Take away to find what's left: 430 − 323. Count up from 323 to 430: +7, +70, +30. Add the jumps: 7 + 70 + 30 = 107.

3
Hint: Share them out one at a time, like dealing cards, until they're all gone. Or think: 4 × ? = 12. 4 × 3 = 12.
Question 4
Which is bigger: 1/3 or 1/8?
- 1/3
- They are the same
- 1/8
1/3
Hint: The more parts a whole is cut into, the smaller each part. 1/3 has the fewest parts, so its part is the biggest.
Question 5
What number comes next?
52, 49, 46, 43,
- 37
- 40
- 39
- 41
40
