Measuring Weight Worksheet

Alfie, Ellis and Idris are preparing parcels in the library makerspace. Use grams (g) and kilograms (kg) to estimate, compare and calculate the weights. Remember: 1 kg = 1,000 g.

Estimate and compare

Think about how heavy each item might be before choosing your answers.

1.A small rubber is likely to weigh about: 5 g, 50 g or 500 g? Circle the most sensible estimate.
  • 5 g
  • 50 g
  • 500 g
2.Ellis has a 1 kg parcel and a 700 g parcel. Which parcel is heavier, and by how many grams?
3.Match each makerspace item to a sensible weight: a paper clip, a full 1 kg bag of modelling clay, and a glue stick.
  • Paper clip
  • Full bag of modelling clay
  • Glue stick
  • 1 kg
  • 25 g
  • 1 g

Weigh and record

The team weighs three parcels. Use the results below to solve the questions.

4.Use the parcel weights to find the total weight of the blue and red parcels.
5.How much heavier is the green parcel than the red parcel?
6.Idris puts the blue and red parcels together. Is their combined weight less than, equal to, or more than 1 kg?
  • Less than 1 kg
  • Equal to 1 kg
  • More than 1 kg

Solve the parcel puzzles

Show how you worked out each answer.

7.A parcel must weigh 1 kg. Alfie has packed 725 g of books. How many more grams can he add?
