Reading scales and measuring

What you'll learn

1. 1

   Imagine a kitchen scale with a dial. When you put an apple on it, the needle moves to show the weight.

2. 2

   If each big line on a scale is 100g, how much is each small line if there are 4 small lines between big ones?

3. 3

   Drag the arrow on this scale to show 350g.

4. 4

   Let's read this scale together. The needle is between 200g and 300g. Each small line is 20g.

5. 5

   Now read this scale. The needle is between 400g and 500g. Each small line is 50g. How many grams?

6. 6

   A scale has big lines every 200g and small lines every 40g. The needle is at the 4th small line after 600g. What is the reading?

7. 7

   What is the reading if the needle is exactly on the 2nd big line after 0, and each big line is 500g?
