Max Maths, Year 5, Work Book, Rounding up or down after division, depending on the context

In the Max Maths Year 5 Workbook, students are presented with practical scenarios that require them to apply their division skills, followed by making a decision to round up or down based on the context of the problem. Practice 5 focuses on this skill through a variety of real-life situations.

For instance, when considering the grassbox on a lawnmower (a), students must calculate the number of times the grassbox needs to be emptied when cutting a lawn that is 200 lengths in size, given that it fills up after 6 lengths. In the case of Jade's cycling routine (b), the workbook asks students to work out how many times her fitness app would beep if she cycled 208 kilometres, with the app beeping every 5 kilometres. Scenario (c) involves assessing whether Toby's father has taken his medication correctly, based on the frequency of dosage and the time elapsed. In a manufacturing context (d), students must determine how many 3 kg tins of curry can be produced in an hour from 170 kg of curry. Lastly, Han's cooking dilemma (e) requires students to figure out how many batches of a recipe he can make with 100 g of butter, with each batch needing 9 g. Each of these problems challenges the students to divide and then make a judgement on rounding to ensure practical and appropriate solutions.
