Units Of Weight Metric Practice Activities
Printable Class 4 maths worksheets for practising metric units of weight, including grams, kilograms, conversions, comparisons, and everyday word problems.
Practice that builds confidence
What this skill covers
These Class 4 maths worksheets help children practise metric units of weight in the Measurement strand. Learners build confidence with grams and kilograms, understand when each unit is suitable, and connect written measurements to real objects such as fruits, packets, books, and school bags.
The printable activities include conversion practice, comparing weights, ordering measurements, simple calculations, and word problems based on daily situations. The focus is on accuracy, unit sense, and clear working rather than memorising answers.
Units of weight in the metric system help children describe how heavy objects are. In Class 4, children usually move from simply reading weights to reasoning with grams and kilograms. These worksheets strengthen the idea that grams are used for lighter objects and kilograms for heavier ones, while also reinforcing the key relationship: 1 kilogram = 1000 grams.
Building conversion confidence
A strong progression begins with identifying the correct unit, then converting between kilograms and grams, and finally using those conversions in sums and word problems. Children may practise examples such as 2 kg = 2000 g or 3500 g = 3 kg 500 g. They also compare measurements, arrange weights from lightest to heaviest, and decide which answer is sensible in a real-life context.
Parent practice routine
At home, keep the practice practical. Ask your child to choose five items from the kitchen or study table and say whether each is better measured in grams or kilograms. Then read labels on rice packets, biscuit packs, or flour bags and write two comparison sentences, such as “1 kg is heavier than 500 g”. Finish with one worksheet section where your child shows all conversions clearly.
Classroom use for teachers
Teachers can use these printables after a lesson on metric weight, in maths centres, for revision, or as a short assessment of unit understanding. They work well with a weighing balance demonstration: first estimate, then measure, then record the weight. Pair work is useful for explaining why a unit was chosen, especially when children confuse a large number of grams with a larger kilogram value.
Common errors to watch for
Many children forget that 1000 grams make 1 kilogram, not 100 grams. Some compare only the number and ignore the unit, so they may think 900 g is heavier than 2 kg. Others write incomplete answers without units. Encourage children to circle the unit, convert both measurements to the same unit before comparing, and include g or kg in every final answer.

Why iBloom worksheets help
The iBloom activities are designed around clear measurement thinking, not random sums. Children meet familiar objects, varied question types, and enough repetition to remember the gram-kilogram relationship. A helpful child-friendly strategy is: “Check the unit, make the units same, then solve.” This simple habit supports conversions, comparisons, and word problems.
Helpful answers
Frequently asked questions
What metric units of weight are covered in these Class 4 worksheets?
The worksheets focus mainly on grams and kilograms, including choosing suitable units, converting between kg and g, comparing weights, and solving simple real-life word problems.
Should my child memorise 1 kg = 1000 g before using these worksheets?
Yes, that relationship is the key fact for this topic. The worksheets also give repeated practice so children can apply it confidently in conversions and comparisons.
How can I help my child understand grams and kilograms at home?
Use everyday items such as spice packets, rice bags, lunch boxes, and books. Ask whether each item should be measured in grams or kilograms, then compare the labelled weights.
What is a common mistake in metric weight questions?
A common mistake is comparing only the numbers and ignoring the units, such as thinking 900 g is heavier than 2 kg. Children should convert to the same unit before comparing.
Can these worksheets be used for revision before a class test?
Yes. They are useful for revising unit choice, kg-g conversions, comparing weights, and measurement word problems in the Class 4 maths Measurement chapter.
Is this class 4 metric units of weight worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
