Q. What are the
totals in the 8
boxes?
What strategies
will you use?

Q. How many totals
change now that
represents a 6
instead of a 5?

Q. If
represents 2, how
many totals will
change?
is 2

you use to help
you first?

How did this help
you?

First you should
have worked out
that

because 4 x 6 in
the last column
gives the total 24.

Q. Which total did
you use next?
is 6

Next you should
have worked out
that

because on the top
row 3x6=18 + 5 =23

Q. Which total did
you use last?
24
is 6
is 5
is _
Last you should
have worked out
that
= 2.

15
In the row totalling
15 you already
have 6 + 5 = 11.
15 – 11 = 4 , there
are 2
so each
must be worth 2.

Work in pairs to
choose your own
number for each

totals.
Then give 3 totals
to another pair for
them to find the

You will do ACTIVITY Sheet 6b1 for
HOMEWORK
this week but we will look
at the first grid now.
WARNING
You may find you need to change your
strategy when you do the last 2 grids.
Let’s try this
as a class.

Q. What do these
totals tell us about
what the shapes
represent?

20
is _
is _

The 20 means that
18
= 10.
+
If this is so then
on the top line,

so

=4
With one more total
we can find

Now try the first question only on
Self-assessment sheet 6b1.
By the end of the lesson the children
should be able to:

To be able to explain methods and
reasoning
.Q. What fraction of these 8 shapes are circles?
Half the shapes are circles :
4/8
½
Q. What fraction of the shapes are circles now?
Three quarters of the shapes are circles: 6/8 ¾
Q. What fraction of the shapes are circles now?
five eighths of the shapes are circles now: 5/8
Q. What fraction of the shapes are circles now?
One eighth of the shapes are circles : 1/8
Now I shall give you the fractions but not the total
number of shapes:
½ the shapes are squares
½ the shapes are circles.
Two squares are replaced with two circles so now
1/3 of the shapes are squares and
2/3 of the shapes are circles.
Q. How many shapes did we start with?
2 minutes
What answers do you have?
What strategies did you use?
Q. If 1/3 of the total number of shapes were
squares what multiplication table will the total
number of shapes be in?
Q. If 1/3 of the total number of shapes were
squares what multiplication table will the total
number of shapes be in?

The only time this happens is when there are 12 shapes.
Try these: use the grid to help you.
Q1.
1/3 of the shapes are squares, 2/3 of the shapes are circles.
Three circles are replaced with three squares.
Now ½ the shapes are squares, ½ the shapes are circles.
How many squares and circles did we start with?
Q2.
1/4 of the shapes are squares, 3/4 of the shapes are circles.
One circle is replaced by one square.
Now 1/3 the shapes are squares, 2/3 the shapes are circles.
How many squares and circles did we start with?
What answers do you have?
What strategies did you use?
There are some cubes in a bag.
1/5 of them are red
4/5 of them are blue
Q. How many cubes might be in the bag?
We know that if we are working in 1/5 ’s
we must be using the 5x table.
I take out 6 blue cubes and replace them with
6 red ones.
Now ½ are red and ½ blue.
Q. How many cubes are in the bag?
Let’s do it.
Remember we are working in multiples of
5
This blank screen is for recording the working.
Now try the second question on
Assessment sheet 6b1.
By the end of the lesson the children should
be able to:
Solve puzzles and problems involving
fractions;
Explain methods and reasoning.

A farmer bought batteries with a
£20
note.
Q. How many of each size could the farmer buy?
1 minute
He could have bought up to
12 large batteries
or up to
18 medium batteries.
If he spent
exactly £20 how
many batteries did the farmer buy?
2 minutes in pairs
Would it help if we
used a list or a chart
or a table?

What strategies did you use?
Q. How many small and large batteries could we buy
for exactly £9?
Q. How many small, medium and large batteries
could we buy for exactly £8?
For extension work try these:
How many small + large for £11; £12 ; £14 ?
How many medium + large for £7 ; £14 ; £20 ?
How many small + medium for £10 ; £13 ; £14 ?
How many small + medium + large for £11 ; £15 ?
Now do question 3 on
Self-assessment sheet 6b 1.
Now that you have finished the questions on the
Self-assessment sheet think about what we
have learned this week in maths and decide on
what you would like to get better at.
Write it as your target at the bottom of the sheet.
By the end of the lesson the children
should be able to:
Solve puzzles and problems
involving money and lists
Explain methods and reasoning
