Max Maths, Year 5, Practice, Ratio

In the Max Maths Year 5 practice on ratios, students are encouraged to apply their understanding of ratios to solve practical word problems. The first set of problems, 'Let's Try It', begins with a scenario involving cookies, where 12 cookies require a mix of 400 g of flour to 200 g of sugar. Students are asked to calculate the amount of sugar needed for 24 cookies. Since 24 is twice as many as 12, they learn to double the amount of sugar from the original recipe, which gives them the required quantity of sugar. Next, they determine how much flour is needed for 6 cookies. Understanding that 6 is half of 12, students halve the amount of flour from the original recipe to find the required amount for 6 cookies.

The final question in the 'Let's Try It' section asks students to work out how many cookies can be made with 1200 g of flour and 600 g of sugar. Recognising that these quantities are three times the amounts in the original recipe, students calculate that they can make three times the initial number of cookies. In the 'Let's Practise' section, students are presented with additional word problems to solve using ratios. They figure out how many cups of water are needed for 2 packets of jelly, the number of minibuses required for a group of 84 people going on a trip, and the quantity of eggs needed for 51 visitors expected at a café. These problems are designed to reinforce the concept of ratios in different contexts and help students develop their problem-solving skills.
