Max Maths, Year 3, Try it, Converting between grams and kilograms

In a Year 3 mathematics exercise, students are encouraged to practise converting between grams and kilograms. The first task presents a notebook computer with a mass of 2,091 grams and asks students to express this weight in both kilograms and grams. They are guided through the process with a formula that breaks down the total grams into a sum of kilograms and grams. The correct conversion will show the mass of the notebook computer in a more comprehensible format, combining kilograms and grams.

The second task involves a bicycle with a mass given as 8 kilograms and 275 grams. Students must convert this combined measurement into just grams. By understanding that 1 kilogram equals 1,000 grams, they can perform the conversion accurately. The exercise continues with a 'Let's Practise' section, where students are given a series of weights in either kilograms and grams or just grams, and they must convert between these units. They are asked to fill in the blanks with the appropriate conversions, reinforcing their understanding of the relationship between grams and kilograms. The practice aims to solidify their grasp of metric units of mass, an essential skill in their mathematical development.
