GoalTell apart numbers that show a price, a time and an amount.
New words
amount · how many or how much there iskilogram (kg) · a way to say how heavy something is
Explanation

Some numbers tell the price. We see the word pounds next to them, like 3 pounds. Some numbers tell the time. They have two dots, like 3:00, and we see them on a clock. Some numbers tell an amount, such as 4 eggs or 2 kg of tomatoes. The word kg says how heavy something is. The words next to a number help us to know what it tells.
