Metric Units Mass Kg Gm Practice Activities
Class 2 maths worksheets for practising mass in kilograms and grams through unit choice, comparison, estimation, and simple measurement problems.
Practice that builds confidence
Building the idea of mass
These Class 2 maths worksheets help children understand mass using kilograms and grams. Learners practise choosing the correct unit for everyday objects, comparing heavier and lighter items, and reading simple measurement situations.
The printable activities include picture-based questions, fill-in-the-unit tasks, matching exercises, comparison problems, and short word problems using familiar objects such as fruits, school bags, packets, and grains.
Mass tells us how heavy something is. In these worksheets, children meet two common metric units: kilogram, used for heavier objects, and gram, used for lighter objects. A bag of rice may be measured in kg, while a pencil or eraser is better measured in gm. This helps Class 2 learners connect maths to real objects they see at home, in shops, and at school.
From unit choice to comparison
The practice usually begins with selecting the sensible unit: kg or gm. Children then compare objects using words such as heavier, lighter, more, less, and equal. Some tasks may show weighing scales or item pictures so learners can decide which object has greater mass without doing long calculations.
Parent routine for home practice
Keep a few safe items ready: a spoon, notebook, fruit, water bottle, and small rice packet. Ask your child, “Would we measure this in kg or gm?” Then sort the items into two groups. If you have a kitchen scale, let the child read a few simple masses and say the unit aloud. Finish with one real-life question, such as, “Which is heavier, the apple or the pencil box?”
Classroom use for teachers
Teachers can use these printables after a hands-on weighing activity, during maths centres, or as quick revision before word problems. Pair work is useful: one child explains the unit choice while the other checks if it makes sense. The sheets also support vocabulary practice for measurement lessons.
Common errors to watch for
Some children choose kg for every object because it sounds familiar. Others think a larger-looking object is always heavier. Watch for missing units in answers and confusion between kg and gm. When the idea is introduced, remind children that 1 kg is much heavier than 1 gm, and that 1000 gm make 1 kg.

Why iBloom worksheets help
iBloom worksheets keep the focus on clear, age-appropriate measurement thinking. The questions move from concrete pictures to simple reasoning, so children do not just guess units; they learn to justify them. A helpful child strategy is: “Small and light, think gm. Big and heavy, think kg.”
Helpful answers
Frequently asked questions
What do Class 2 children practise in kg and gm worksheets?
They practise identifying whether an object should be measured in kilograms or grams, comparing heavier and lighter items, and solving simple mass-based questions using everyday examples.
Should my child know the conversion between kg and gm?
At this level, the main focus is understanding which unit is suitable. Children may also be introduced to the fact that 1000 gm make 1 kg, but complex conversions are not the main aim.
How can I explain the difference between kg and gm at home?
Use real objects. Show a rice packet or school bag for kg and a pencil, spoon, or eraser for gm. Let your child hold the objects and say which unit fits better.
What mistakes are common in metric mass practice?
Children may use kg for very light objects, forget to write the unit, or decide only by size instead of weight. Encourage them to think about how heavy the object would feel.
Are these worksheets useful without a weighing scale?
Yes. Many activities use pictures, comparisons, and unit selection. A weighing scale can make the lesson more concrete, but it is not required for every worksheet.
Is this Class 2 metric units mass kg gm worksheet free?
Yes. You can preview it for free and use the printable worksheet for home or classroom practice.
Can I download this Class 2 metric units mass kg gm worksheet as a PDF?
Yes. Use the worksheet download option to save a printable PDF, or print the worksheet directly from the page.
Does this Class 2 metric units mass kg gm worksheet include answers or an answer key?
When the activity has fixed answers, iBloom includes answer support so parents and teachers can check the completed worksheet.
