Mathematics Topical Test
Date : Next Wednesday, 23rd September.
Topics tested are : Volume, Time, Money and Fractions
Areas of Weakness
The questions posted below are extracted from their worksheets. These are the questions some children have difficulty comprehending and thus made mistakes.
TimeExample: Look at the clock shown.
(1) Jane's watch is 15 minutes slower than the clock.
What is the time shown on Jane's watch?
Tom's watch is 10 minutes faster than the clock.
What is the time shown on Tom's watch?
(2) Fiona completed exercising at 8.40 a.m.
She started exercising 2 hours 20 mins ago.
What time did she start for exercising?
(3) Parking Fees
Duration Price
First Hour $3
Subsequent hour or part thereof $1
(a) If Sam parked his car in the car park for 3 hours, how much must he pay?
(b) If his friend paid $8, how many hours did he park his car at the same car park?
(4) Must remind them if they are told to draw the hands for ( let's say 9.45p.m.) , they must take note of the following:
(a) The minute hand must be longer than the hour hand
(b) The hour hand must be between 9 and 10.
Many children drew the hour hand at either 9 or 10.
Fractions
(1) A cake was cut into 6 pieces.
James took one piece and ate 1/2 of it.
(a) What fraction of the cake did he eat?( Answer : 1/12)
(b) What fraction of the cake was left? (Answer: 11/12)
Children should draw the cake with six equal parts and further cut each slice into half.)
(2) Benny drew a flag. ( Must remind them that it is a whole.)
He coloured 2/8 of it green and 3/8 of it blue.
He left the rest of the flag uncoloured.
(a) What fraction of the flag was coloured?
(b) What fraction of the flag was not coloured?
VolumeNote the following:
1 litre
1 cup of 1000ml = 1 L
2 cups of 500ml =1L
4 cups of 250ml = 1L
5 cups of 200ml =1L
10 cups of 100ml = 1L
Conversion of ml into L and vice versa
E.g. 6000ml = 6L or 5L = 5000ml
They are not taught the mixed combinations. (e.g. 1L 600ml = 1600ml)
Hope that the above information will help you when you revise the work with your child!
