What’s Included in the Mass and Weight Worksheets PDF
The printable workbook contains six varied measurement pages:
- Lightest, heavier, and heaviest picture comparisons
- Cut-and-order objects from lightest to heaviest
- Pan-balance heavier-side identification
- Equal-mass scale recognition
- Flower and cat mass-comparison drawing activity

The activities progress from basic visual comparisons to more independent prediction, drawing, and written reasoning.
Lightest Items Activity
The first worksheet asks children to circle the two lightest items from a group containing:
- Giraffe
- Feather
- Bathtub
- Paper airplane
Children compare the likely mass of each item and identify the feather and paper airplane as the lightest objects.
This activity develops:
- Everyday mass awareness
- Comparative reasoning
- Object recognition
- Vocabulary such as light and lightest
- Visual decision-making
Circle the Heavier Item
Another question on the first page asks children to compare:
- A pillow
- An elephant
Children circle the elephant as the heavier item.
This simple comparison helps learners understand that “heavier” is used when comparing the mass of two objects.
Circle the Heaviest Item
Children also compare:
- Car
- Bus
- Toilet
- Teddy bear
They identify the bus as the heaviest item.
This question introduces comparison across several objects rather than only two choices.
Light, Lighter and Lightest Vocabulary
The workbook introduces comparative measurement words.
Children learn that:
- Light describes an object with relatively little mass.
- Lighter compares two objects.
- Lightest identifies the object with the least mass in a group.
Examples from the worksheets include a feather and paper airplane as light objects.
Heavy, Heavier and Heaviest Vocabulary
Children also practice:
- Heavy
- Heavier
- Heaviest
For example:
- An elephant is heavier than a pillow.
- A bus is heavier than a teddy bear.
- The bus is the heaviest item in its comparison group.
Understanding these words helps children communicate measurement comparisons clearly.
Order Objects from Lightest to Heaviest
The second worksheet asks children to cut out four pictures and place them in order from the lightest to the heaviest.
The objects include:
- Pencil
- Shoe
- Bear
- Large dinosaur
Children compare the expected mass of each object and arrange them in sequence.
A likely order is:
- Pencil
- Shoe
- Bear
- Dinosaur
The activity combines mathematical comparison with cutting, sorting, and sequencing.
Cut-and-Paste Measurement Activity
The ordering page includes four empty spaces where children place the cut-out pictures.
This hands-on format develops:
- Mass comparison
- Logical ordering
- Sequencing
- Scissor control
- Fine motor coordination
- Independent decision-making
Adult supervision is recommended when young children use scissors.
Understanding a Pan Balance
The third worksheet introduces pan balances.
Children learn that:
- The heavier side moves downward.
- The lighter side rises upward.
- Equal masses keep the balance level.
The illustrations provide clear examples of tilted and balanced scales.
Circle the Heavier Side of the Balance
Children examine two tilted pan balances and circle the side that is lower.
Because the lower pan represents the heavier side, learners use the visual position of the scale to determine the answer.
This activity supports:
- Balance-scale interpretation
- Visual comparison
- Understanding cause and effect
- Measurement reasoning
- Direction vocabulary
Identify Objects with the Same Mass
The same page shows three pan balances.
Children circle the scale where both pans are level, indicating that the objects have equal mass.
They learn that:
- A level balance means both sides have the same mass.
- A tilted balance means one side is heavier.
- The lower side has greater mass.
- The higher side has less mass.
Equal and Unequal Mass
The worksheets introduce the difference between equal and unequal mass.
Equal mass means:
- Both sides balance
- Neither side moves lower
- The scale beam remains level
Unequal mass means:
- The scale tilts
- The heavier side moves down
- The lighter side moves up
These concepts prepare children for later work with standard and nonstandard units of measurement.
Flower and Cat Pan-Balance Drawing Activity
The fourth page presents a flower and a cat on opposite sides of an imagined pan balance.
Children draw a picture showing the expected mass difference.
Because a cat is heavier than a flower:
- The cat’s side should be lower.
- The flower’s side should be higher.
- The balance beam should tilt toward the cat.
This activity requires children to apply their understanding rather than select from prepared answers.
Representing Mass Through Drawing
The flower-and-cat question helps children translate a verbal comparison into a visual model.
Children practice:
- Interpreting a written problem
- Predicting which object is heavier
- Drawing a tilted pan balance
- Showing the heavier side lower
- Explaining a mass relationship visually
Draw Two Items with Similar Masses
The fifth worksheet asks children to draw two objects with similar masses.
Possible examples include:
- Two pencils
- Two books of similar size
- An apple and an orange
- Two toy cars
- Two crayons
This open-ended activity helps children connect measurement vocabulary with real objects in their environment.
Draw Two Light Objects
Children also draw two items considered light in mass.
Possible examples include:
- Feather
- Paperclip
- Leaf
- Tissue
- Balloon
- Sheet of paper
The activity encourages children to think beyond the pictures provided in the workbook.
Draw Two Heavy Objects
The final drawing task on page five asks children to draw two heavy objects.
Examples may include:
- Car
- Bus
- Elephant
- Refrigerator
- Large table
- Brick
Answers may vary because the worksheet encourages independent reasoning.
Brick and Paperclip Prediction Activity
The final worksheet asks children to describe what would happen if a brick were placed in one pan and a paperclip in the other.
Children should predict that:
- The brick side will move downward.
- The paperclip side will rise upward.
- The scale will not remain balanced.
- The brick has greater mass than the paperclip.
The page includes space for both a written explanation and a drawing.
Written Mathematical Reasoning
The brick-and-paperclip question asks children to explain their reasoning using words.
A suitable response is:
- The brick side will go down because the brick is heavier than the paperclip.
This develops the ability to communicate a mathematical conclusion rather than only mark an answer.
Prediction and Scientific Thinking
Before drawing the balance, children predict what will happen.
Prediction activities encourage learners to:
- Use prior knowledge
- Compare object masses
- Anticipate the movement of the scale
- Explain cause and effect
- Check whether the drawing matches the explanation
These skills are useful in both mathematics and early science.
Objects and Animals Featured in the Workbook
The worksheets use familiar pictures such as:
- Feather
- Paper airplane
- Bathtub
- Pillow
- Car
- Bus
- Toilet
- Teddy bear
- Pencil
- Shoe
- Flower
- Brick
- Paperclip
- Giraffe
- Elephant
- Bear
- Dinosaur
- Cat
Using familiar objects helps children estimate mass without needing numerical measurements.
Estimating Mass Without Standard Units
Most activities ask children to estimate which item is heavier or lighter based on everyday experience.
Children do not need to use kilograms or grams.
Instead, they compare:
- Object size
- Material
- Real-world experience
- Expected heaviness
- Balance position
This provides a foundation for later measurement using standard units.
Mass Versus Weight for Early Learners
At this level, the worksheets use the terms mass and weight in an introductory, everyday way.
Children focus on:
- Which object is lighter
- Which object is heavier
- Which side of a balance moves down
- Whether two items have similar or equal mass
- How objects can be ordered by heaviness
Formal scientific distinctions between mass and weight can be introduced at a later stage.
