M2.6.4 For the adult
Grams and kilograms
Is a big thing always heavier than a small thing?
What this chapter teaches
Light things are weighed in grams and heavier things in kilograms, and 1 000 g make 1 kg. A bigger thing is not always heavier, because weight does not depend on size alone. A balance shows which of two things is heavier.
Three questions to ask
There is no one right wording. Listen for the idea.
- Which feels heavier to you, a big pillow or a small stone, and how could you check?
- A scale arrow is past 2 kg. How do you read the weight from the marks?
- How would you say 2 kg 300 g using only grams?
After the chapter, the learner can
- Weigh things on a scale in grams and kilograms
- Read a scale where the marks go up in 100 g
- Change 2 kg 300 g into 2 300 g
What they copy into their notebook
1 000 g make 1 kg. 2 kg 300 g is 2 300 g. On a scale, count 100 g marks from the last number. Big is not always heavy.
