Heavy Or Light
Heavy or Light introduces children to weight comparison using everyday objects sorted into “heavy” and “light” categories. By holding and comparing items, children develop early measurement concepts, observation skills, and problem-solving abilities. Use clearly different weights and adjust complexity by age.

What do you do:
Explain “heavy” and “light” with examples (penny = light, book = heavy)
Have the child hold one item in each hand to feel the difference
Show how to sort light items into one basket and heavy items into another
Encourage weighing and sorting all items by weight
What's Needed:
Two baskets or trays
Items to weigh, such as: rock, penny, pencil, water-filled bottle, spoon, crayon, magnet, chalk, candle, and book
How to Adapt
Toddlers: Use simple objects with clear weight differences. Focus on feeling and naming “heavy” and “light.”
Preschoolers: Sort multiple items into heavy/light groups. Use balance scales to compare weights
Older Kids: Use scales for precise weighing. Challenge with similar-looking objects of different weights. Introduce volume vs. mass concepts
