New unit - Measurement

Today we started a new unit on measurement. This involves firstly reminding ourselves how we convert between the units we use when measuring lengths (i.e. meters, centimeters, millimeters, kilometers). Once we have mastered this, we will go on to calculate the perimeter and area's of shapes, as well as the volume of prisms.

To start with, we will look at converting between units of length. First of all, we have to remind ourselves of the difference between each. We need to remember that:

• 1 kilometer is 1000 meters
• 1 meter is 100 centimeters
• 1 centimeter is 10 millimeters

Now to convert between each, the following diagram is really helpful:

Because there are 1000 meters in a kilometer, if we wanted to find out how many meters 3 kilometers were, we would multiply the 3 by 1000, as the diagram says. The diagram also shows us how to convert between many different units. It is important to remember that km is short for kilometers, m is short for meters, cm is short for centimeters, and mm is short for millimeters. 

I have uploaded a worksheet into the "Worksheets" tab. I have circled the questions I would like you to do. If you use this diagram, this worksheet should be quite easy to complete, so simply finish off this sheet for homework by Thursday. 

As always, feel free to comment on this post if you have any questions on this topic, or email me or chat to me in person.
