Measuring Liquids & Masses

Mathematics · Measurement · procedural

Measure and estimate liquid volumes and masses of objects using grams, kilograms, and litres; solve one-step word problems involving mass or volume

What mastery looks like

  • Estimate the mass of a textbook in grams or kilograms
  • Read a scale to measure liquid volume in litres
  • Solve: 3 bags weigh 250 g each — what is the total mass?

Check your understanding

If Measuring Liquids & Masses is filling bottles that each hold 250 ml from a 2-litre container of juice, can they work out how many bottles they can fill?
