  1. 1000 · Read the aligned label and keep its unit: 1000 ml.
  2. Weigh the lunchbox on a scale · Weighing gives a measured mass that Nia can compare with her estimate.
  3. 900 grams · 1 kg is 1000 g. An estimate of 900 g is nearby and a little lighter; 900 kg is far larger.
  4. True · 200 g + 350 g = 550 g.
  5. 750 · 450 ml + 300 ml = 750 ml.
  6. 2000 g · Four equal masses of 500 g total 4 x 500 = 2000 g.
  7. 750 g · Subtract what is used: 900 g - 150 g = 750 g.
  8. True · The known benchmark is 1000 g. An estimate of 20 g is far below it.
  9. 8 · Each litre contains four 250 ml portions. Two litres contain eight portions.
  10. 250 · 1000 g shared equally among four packs gives 250 g per pack.
