Measurement Matters Worksheet
Help the aquarium team plan a new touch pool. Choose sensible units, convert measurements and solve practical problems. Show your working and include units in your answers.
Choosing units and tools
The aquarium team is measuring equipment for the touch pool.
1.Oliver records that the touch-pool tank is 2.4 long. Which unit makes the most sense?
- millimetres (mm)
- centimetres (cm)
- metres (m)
2.Mele needs the mass of a small bag of shell grit. Which tool and unit should she use?
3.A refill container holds 18 L of water. Convert this capacity to millilitres.
Convert and compare
Use these facts: 1 m = 100 cm = 1,000 mm; 1 kg = 1,000 g; 1 L = 1,000 mL.
4.A clear tube is 2,350 mm long. Convert its length to metres and centimetres.
5.Sione weighs out 0.65 kg of shell grit. How many grams is this?
6.The touch pool needs 2.75 L of fresh water. The measuring jug is marked in millilitres. What amount should the team pour?
7.A roll of protective edging is 3.6 m long. The team uses 245 cm. How many centimetres of edging remain?
Estimate and solve
Think about whether measurements are sensible before calculating.
8.True or false? A 600 mL bottle can hold less than 1 L of water.
TrueFalse
9.Which is the most reasonable estimate for the mass of a full 10 L bucket of water: 10 g, 10 kg or 100 kg? Explain briefly.
10.The aquarium team has 4.5 L of water and fills bottles holding 750 mL each. How many full bottles can they fill? Show your conversion or calculation.
11.The tank is 1.8 m long. Oliver estimates it is 18 cm long. Is his estimate reasonable? State the correct length in centimetres and explain why.
