Max Maths, Year 4, Learn together, Word problems (2)

In the Max Maths Year 4 curriculum, students are encouraged to apply their knowledge of measurement to solve word problems. One such problem involves a swimming pool with a length of 40 metres. To find the width, which is half of the length, students are taught to divide the length by 2, resulting in a width of 20 metres. The next step is to calculate the perimeter of the pool, which is the sum of twice its length and twice its width. By adding 2 times 40 metres and 2 times 20 metres, students find that the perimeter is 120 metres. Finally, to determine the area of the pool, they multiply the length by the width, which in this case is 40 metres times 20 metres, yielding an area of 800 square metres.

The lesson continues with practice exercises to reinforce these concepts. For instance, students are asked to calculate the dimensions of a square bathroom tile given its perimeter of 20 centimetres. They need to deduce the length of one side and then find the tile's area. Another problem presents a driveway with a length of 12 centimetres and a width of 5 metres, where students are tasked with finding both the area and perimeter. Through these exercises, students learn to apply mathematical formulas for perimeter and area in practical scenarios, enhancing their problem-solving skills.
