Week 4 – Measurement: Area
Children are introduced to area for the first time. They
will understand that area is how much space is taken up
by a 2D shape or surface.
Children recognise why squares are used to measure
area and understand why other things such as circles
cannot be used (link to gaps between circles).
Give children a pre-cut piece of paper that measures 15 cm
by 15 cm
How many post it notes cover
your piece of paper?
Give the children 10 squares, 5 measuring one measurement
and 5 measuring another (e.g. 5 squares measuring 5 cm by
5 cm and 5 squares measuring 10 cm by 10 cm)
Make the same shape using the smaller squares and the
larger squares.
E.g.
How many post it notes cover your piece of paper?
Using the post it notes what would have a smaller area
or larger area than your piece of paper?
Which square is larger/smaller? Which squares will
cover a larger/smaller area?
If I wanted to find the surface area of…what size square
would I use? Why can we not use other shapes to find
the area?
Discuss which has the larger area and why.
Look at the shapes and
discuss what’s the same
and what’s different?
Which shape has the
largest area?

Week 4 – Measurement: Area
Leona is finding the area of a floor tile.
I disagree. Leona
has gone over the
edges of the tile.
Each square should
fit exactly over the
tile.
Two children have measured the top of
their desk. They used different sized
squares.
The area of the
table top is 7
squares.
Nima
The area of the
table top is 12
squares.
Nima needed fewer
squares to cover
the space, so her
squares must have
been the bigger
ones. If the squares
are smaller, you
need more of
them.
She says the area is 16 squares.
Do you agree?
Explain why.
Jen
Who used the biggest squares? How do
you know?
