Question 1
What is 365 − 17?
365 − 17 = ?
- 348
- 358
- 352
- 338
348
Hint: Count up from 17 to 365: +3, +80, +200, +60, +5. Add the jumps: 3 + 80 + 200 + 60 + 5 = 348.
Question 2
Which multiplication means the same as this?
2 + 2 + 2 + 2 + 2
- 6 × 2
- 5 + 2
- 5 × 2
- 2 × 2
5 × 2
Hint: There are 5 groups of 2 added together, so it's 5 × 2 = 10.
Question 3
5 × 5 = 25. So what is 25 ÷ 5?
25 ÷ 5 = ?
- 5
- 4
- 6
- 25
5
Hint: Multiplying and dividing undo each other. 5 groups of 5 make 25, so 25 split into 5 groups is 5.
Question 4
Which is bigger: 1/3 or 1/8?
- They are the same
- 1/3
- 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
Which equation matches the story? The is the number we don't know.
Ana had some shells.
Then Ana got 36 more.
Now Ana has 92.
- ☐ + 36 = 92
- 92 + 36 = ☐
- ☐ − 36 = 92
☐ + 36 = 92
Hint: Some shells, plus 36 more, makes 92. So ☐ + 36 = 92.
Question 6
Which unit would you use to measure the mass of a feather?
🪶- kilograms
- milliliters
- grams
grams
Hint: Grams are for light things, like a paper clip. Kilograms are for heavy things, like a bag of potatoes. 1 kilogram is 1000 grams.
Question 7
Round 6032 to the nearest thousand.
- 5000
- 6000
- 8000
- 7000
6000
Hint: To round to the nearest thousand, look at the hundreds digit: 0. It's less than 5, so round down to 6000.
Question 8
Round 349 to the nearest ten.
- 340
- 350
- 300
350
Hint: Look at the ones digit. 5 or more, round up. Less than 5, round down.
Question 9
Which shape is a polygon?
- An oval
- A circle
- A square
A square
Hint: A circle has no straight sides.
Question 10
What is 7 × 60?
7 × 60 = ?
- 4200
- 67
- 420
- 42
420
Hint: 7 × 6 = 42, so 7 × 6 tens = 42 tens = 420.
