In this lesson, we will learn:

- Metric units of length, volume and weigh
- Comparing and Converting between different metric units
- Choosing appropriate units to make measurements

1km = 1000 m

1 m = 100 cm

1 cm = 10 mm

1L = 1000 mL

1kg = 1000 g

- IntroductionIntroduction to Metric Unitsa)Introduction to measuring length
- What is length?
- How do we measure length?
- Metric Units of Length: millimetre, centimetre, meter, kilometer

b)Intro to metric conversionsc)Converting in two steps and three stepsd)Introduction to measuring weight- What is weight?
- How do we measure weight?
- Metric units of volume: gram and kilogram

e)Converting between metric units of weightf)Introduction to measuring volume- What is volume?
- How do we measure volume?
- Metric units of volume: millilitre, litre

g)Converting between metric units of volume - 1.
**Choose the appropriate metric unit of measurement**

Which unit would you use to measure? (mm, cm, m, km)- Length of a pencil
- Length of a football field
- Thickness of a coin
- Distance between two cities

- 2.
**Converting Metric Units of Length**

Convert:a)200 cm into mb)10 m into mmc)200 m into km - 3.
**Converting metric units of volume**

Convert:a)2 litres into millilitresb)2500 millilitres into litres - 4.
**Converting metric units of weight**

Convert:a)3 kilograms into gramsb)500 grams into kilograms - 5.
**Comparing Metric Units of Length**

Compare the following lengths using <, =, >a)10cm, 100mmb)2m and 150 cm 20mm - 6.
**Comparing Metric Units of Volume**

Compare the following volumes using <, =, >a)800ml and 1 Lb)5000 mL and 3L 150ml - 7.
**Comparing Metric Units of Weight**

Compare the following weights using <, =, >a)2000 g and 1 kgb)2.5 kg 50g and 2000g - 8.
**Word Problems with Metric Units**a)Annie and Jessica are both going for hikes. Annie went on 6km hike while Jessica went on a 4500m hike. Jessica says she had a longer hike. Is she correct?b)Ben is asked to get 0.5 L of orange juice from the store. The store has 750 mL juice bottles or 500 mL juice bottles. Which one should he buy?
