Margo's soccer coach brought a large bag of watermelons to practice. The mass of the bag with all the watermelons in it was 12 kilograms.
Explain how you could use estimation to figure out how many watermelons are in the bag.

The average weight of a watermelon is about 10 kg. There are probably 1 or 2 watermelons in the bag.
Of course these could be a smaller variety of melon  perhaps weighing only 3 or 4 kg each.
