Max Maths, Year 5, Learn together, Review of measuring mass

In a Year 5 mathematics lesson, students review the concepts of measuring mass, an essential skill in both science and everyday life. The lesson revisits the two main units of measurement for mass: grams (g) and kilograms (kg). Grams are typically used for lighter objects, while kilograms are suitable for heavier items. As part of the learning process, students are encouraged to apply their knowledge by choosing the appropriate unit of measurement for various objects. Examples include determining whether to use grams or kilograms for items like a spoonful of sugar, a sack of rice, a bicycle, and a hand-sized stone.

The lesson continues with a review of measuring volume, another fundamental aspect of measurement. Students are reminded of the units used to record volume: millilitres (ml) and litres (l). They are then tasked with selecting the correct unit to measure different volumes, such as a glass of water, the contents of a full bucket, the amount of water used by a shower in 10 minutes, and the concentrate needed to make one litre of cordial. This hands-on practice helps to reinforce the understanding of volume measurement and the appropriate contexts for using each unit. To further consolidate their learning, students are directed to workbook page 189 for additional exercises and examples.
