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

In a practical application of maths for Year 4 students, they are faced with a word problem that involves scaling down a recipe. The original recipe is designed to make 48 cupcakes and requires 8 eggs. The problem asks the students to determine how many eggs would be needed to make only 12 cupcakes instead. To solve this, students are encouraged to use a bar model, a visual tool that represents the proportional relationship between the number of cupcakes and the number of eggs. By understanding that 48 cupcakes can be divided into 4 groups of 12, they can deduce that each group of 12 cupcakes requires 2 eggs, since 4 times 2 equals the original 8 eggs needed for the full recipe.

The 'Let's Try It' section offers another scenario for the students to apply their problem-solving skills. This time, the question involves calculating the total number of people on 4 minibuses if one minibus can hold 18 people. Students are then asked to further divide this total number when all passengers from the minibuses are split into 3 equal groups. These exercises not only test the students' multiplication and division skills but also their ability to apply these operations in real-world contexts, reinforcing their understanding of how to work with numbers in practical situations.
