 ## 5 Tough PSLE Math 2019 Questions

The PSLE Math 2019 Paper was said deemed to be a “killer paper” by many students and parents.

There were reports of parents being upset over the high difficulty, leaving many pupils in tears after the paper.

We have looked through the PSLE Math 2019 paper and shortlisted 5 tough questions.

We will share our solutions of the 5 questions through the videos below. ## 1) Fraction (From Paper 1 MCQ)

Pupils in a school are put into two groups for a learning journey. 2/5 of the pupils are in Group A and the rest are in Group B.  1/4 of the pupils in Group A are girls. In the school, 3/10 of the pupils are girls. What fraction of the pupils in Group B are girls?

This question is testing the Part-Whole Concept. Your child needs to be very clear on the differences between “Fraction of a part” vs “Fraction of a Whole”.

Watch the video below for the solutions.

## 2) Volume (From Paper 2)

Jack has 8 identical large cubes and some identical small cubes. He packed all the cubes tightly into a rectangular box such that cubes of the same size are stacked on top of each other.
The box is filled to its brim exactly. The figure shows the first layer of cubes packed in the box.

a) How many small cubes does Jack have?

b) The volume of the box is 4032 cm³. The total volume of the 8 large cubes is 3/7 of the volume of the box. What is the length of one edge of the small cube? Part a is the tricky question. Your child needs to spot the relationship between the large cube and small cube. Part b cannot be done without solving part a first.

## 3) Percentage Discount (From Paper 2)

Jamie and Oliver used \$61.20 each to buy some egg tarts. Jamie has a 15% discount coupon and bought 6 more egg tarts than Oliver.

(a)How many egg tarts did Jamie buy?

(b)What is the cost of an egg tart without the discount?

Your child needs to be clear on the percentage discount concept. Once your child is able to find the discounted price and the original price, this question will become a piece of cake (Not Egg Tart).

## 4) Circles (From Paper 2)

Five identical semi-circles are arranged as shown. Find the diameter of one circle. This question is actually manageable.

The easiest way is to use algebra and let the diameter be 1 unit. From there, form an equation to find the value of 1 unit.

## 5) Patterns (From Paper 2) Figure 1 2 3 4 5 White triangles 1 1 6 6 Grey triangles 0 3 3 10 Total 1 4 9 16 25

(a) Fill in the table above.

(b) Find the total number of white and grey triangles for Fig. 250.

(c) Find the percentage of grey triangles in Fig. 250.

This is probably the hardest question in the PSLE Math 2019 paper.

Patterns questions can be quite tough. There are a few patterns in this question. Can your child spot all of them?

Watch the video below for the solutions.

Though some of the questions in the PSLE Math 2019 paper are exceptionally hard, most are actually manageable.

Even if your child could not do certain parts of the question, marks will still be awarded for the earlier parts and correct workings.

Nonetheless, we find the difficulty level of PSLE Math has increased over the year.

Questions are not so straight forward and require your child to apply the concepts correctly.

We hope that our sharing of our solutions has taught your child something useful and also let you have a better idea of the types of PSLE Math questions.
