Grade 5 Math practice sheet
New Brunswick Curriculum · from Gradelings · Name: ______________________
Question 1
Round 436 406 to the nearest ten thousand.
- 440 000
- 400 000
- 436 000
- 430 000
440 000
Hint: Look at the digit just to the right of the ten thousands place. If it is 5 or more, round up; if it is less than 5, round down. Then every place to the right becomes 0.
Question 2
A school wants to collect 50 000 cans of food. Grade 4 collected 14 756 and Grade 5 collected 16 126. How many more cans do they need?
- 20 118
- 33 874
- 19 118
- 30 882
19 118
Hint: This takes two steps. First add the two amounts collected. Then subtract that total from the goal.
Question 3
6 × 7 = ?
- 42
- 36
- 48
42
Hint: Think 6 × 6 = 36, then add one more 6.
Question 4
Which product is the greatest?
- 59 × 15
- 59 × 31
- 27 × 23
- 13 × 21
59 × 31
Hint: Estimate each product with friendly numbers. If two estimates are close, work those out exactly.
Question 5
Which is the best estimate for 923 ÷ 6?
- 15
- 300
- 150
- 1500
150
Hint: Change 923 to a nearby number that divides easily by 6, like 900. Then divide the friendly number.
Question 6
Which fraction is greater than 1/2?
- 1/7
- 2/12
- 7/11
- 3/6
7/11
Hint: A fraction is greater than 1/2 when its numerator is more than half of its denominator. Exactly half means it equals 1/2.
Question 7
Write 1/100 as a decimal.
1/100 = ?
answer box
0.01
Hint: The denominator tells you the last place: 10 → tenths, 100 → hundredths, 1000 → thousandths. Use zeros to fill any empty places.
Question 8
Solve for a.
a × 4 = 48
answer box
12
Hint: Think: 4 times what number makes 48? Divide 48 by 4 to undo the multiplying.
Question 9
Two rectangles have the same perimeter. Must they have the same area?
- Yes, always.
- No, their areas can be different.
- Yes, if they are rectangles.
- Only if they are both red.
No, their areas can be different.
Hint: Try two rectangles with a perimeter of 20 m: 9 m by 1 m and 5 m by 5 m. Find both areas.
Question 10
Which holds more?
- a 500 mL bottle
- a 2 L jug
- a 250 mL cup
a 2 L jug
Hint: 2 L is 2 000 mL.
