3rd Grade Time, Liquid Volume and Mass Quiz: 10 Questions with Explanations

A 6:41B 5:08C 5:41D 4:41

The minute hand is 1 mark past the 8 (40 + 1 = 41). The hour hand has not reached 6, so the hour is 5. Reading the nearest hour number gives the mistake 6:41.

A 4 LB 6 LC 50 LD 5 L

The top of the water is on the unlabeled mark between 4 and 6, so it is 5 L.

A 300 gB 450 gC 35 gD 350 g

The pointer is halfway between 300 and 400, which is 350. Reading only the nearest labeled number gives 300.

A 60 minutesB 110 minutesC 50 minutesD 40 minutes

6:15 to 7:00 is 45 minutes and 7:00 to 7:05 is 5 minutes, so 50 minutes. Subtracting the hours and minutes separately causes mistakes.

A 10:15B 9:75C 10:25D 10:05

9:25 plus 35 minutes is 10:00, and 15 more minutes is 10:15. There is no 75 in a clock hour.

A 5 gB 5 kgC 50 kgD 500 g

A pencil is very light, so grams are the right unit. A mass of 5 kg is about the same as a large bag of dog food.

A 27 LB 4 LC 45 LD 9 L

Equal sharing means divide: 36 divided by 9 is 4. Adding or subtracting would not share equally.

A 21 kgB 9 kgC 8 kgD 10 kg

To find what is left, subtract: 15 – 6 = 9. Adding gives 21.

A 12:15B 1:05C 12:25D 12:05

Count back 25 minutes from 12:40. 40 – 25 = 15, so lunch started at 12:15. Adding 25 gives the wrong answer 1:05.

A 10 LB 21 LC 24 LD 4 L

Seven equal groups of 3 L: 7 times 3 is 21. Adding 7 and 3 gives 10.
