Year 5 and 6
In today’s lesson we are looking at the area of irregular shapes. This is a year 5 objective, but is something we always revise with year 6. I have frequently watched year 6 children in a SATs test try to calculate the area of an irregular shape using a formulae because they are so confident with finding area this way for rectilinear shapes. It isn’t possible to do this for irregular shapes! You need to work out your estimate by counting the squares. In the video, they number each square. I tend to dot them so I don’t end up counting each square more than once and keep a tally in my head. Either way, you cannot estimate the area without marking each square – trust me!!

Area of irregular shapes
The first sheet I have set you is counting squares where there are half squares which can be paired up to make whole squares . Your answer is either right or wrong. The second sheet is slightly harder than the first; you can choose if you do both, or the first or second.

The second sheet involves estimating the area by counting the squares of irregular shapes without straight lines. The answers are all whole numbers and you are allowed to be one cm above or below their answer!

The challenge is to do all seven!! In my experience, it is the children that are more careful and don’t rush who are more accurate not the children who are better mathematicians.
Thursday 4th March
Today we are looking at the area of triangles. This is a year 6 objective, but children in year 5 who are confident finding the area of rectangles always find this quite easy to grasp. In our mixed age class, we tend to teach this to year 5.
In today’s lesson you will use your previous knowledge of estimating and counting to work out the area of different triangles.

The challenge is the second sheet drawing your own triangles. Take care -use a ruler and a sharp pencil.

Today you will be using your knowledge of the area of rectangles to find the are of a right angled triangle.

Year 5 I am happy for you to just do the first sheet . However if you wish to carry on, you can do the second part of the sheet.

ARITHMETIC
Again, I am including two short arithmetic papers. It is IMPORTANT that you attempt these as scores in the arithmetic paper are easy marks in s SATS test and your ability to calculate allows you to tackle the reasoning problems in the reasoning papers.
