Maths

This week we will be focusing on measurement. We will revisit how to measure accurately using a ruler before moving on to comparing measurements, adding and subtraction measurements, finding the perimeter of 2d shapes and solving measurement word problems. 

Units of measurements: Length

  • Millimetres (mm) is a measurement used for very small things
  • Centimetres (cm) is a measurement used for slightly larger things, such as a glue stick or a book.
  • Metres (m) is a measurement used for larger things such as the whiteboard or the bookcase

We will use column method to add and subtract measurements. Lets revisit the steps for using column method:

 

Finding the Perimeter:

Do you know what the perimeter is?

We will be finding the perimeter of 2d shapes, use the following link to watch a short video about finding perimeter by clicking the link here.
