Take away the 4 corners: 150 - 4 = 146 Divide the rest equally for the the 4 sides: 146 / 4 = 36.5 So each side can have a max of 36 Pots needed on one side - 36 + 2 (one top corner, one bottom corner) = 38

Accidentally cropped out bottom of solution! Lol! 😂 Ali's weight is 46.6 + 6.1 = 52.7kg

Here is also another way. :) I added 6.1kg and subtracted 1.95kg from the total so that I get 3 times of Ali's mass. This question frequently occurs at P5. The skill involved is to make each model the same size so that you can apply division. :) So, Jane JJ and Jason Oon, correct me if I am wrong, you all removed the 6.1 kg x 2 and 1.95kg to make each model equal to Bala's mass so that you can add 6.1kg to Bala's mass to find Ali's mass. There is also one more way. Who wants to try? :)

Good to have different solutions, so that children are not restricted to "model answers". Instead, they would be creative and work out questions in their own way. 👍

For the last way, the hint is to make every model to the length of Colin. :)

Based on the working, the student took 48 units to be the fenced area of the garden. Hence, the student added 48 and 31 units together to represent the total area of the garden. Actually, the 48 units represented the total area of the garden. Hence, the student added 48 units and 31 units together to represent the total area of the garden. So, what Jason Oon did in his solution was to show that the 48 units represented the area of the garden. :)

This video does not make use of any models. Instead, it makes use of a method we call grouping or pairing in order to solve the question. This is a very straight forward question that we cannot skip. Going by how the PSLE was presented this year, there seems to be a greater focus on fundamental math concepts. Watch the entire video for my take on the importance of fundamental mathematics concepts in the study of Mathematics.
