In this document, you will find suggestions of how you
may structure a progression in learning for a mixed-age
class.
Firstly, we have created a yearly overview.
Each term has 12 weeks of learning. We are aware that
some terms are longer and shorter than others, so
teachers may adapt the overview to fit their term dates.
The overview shows how the content has been matched
up over the year to support teachers in teaching similar
concepts to both year groups. Where this is not possible,
it is clearly indicated on the overview with 2 separate
blocks.
For each block of learning, we have grouped the
small steps into themes that have similar content.
Within these themes, we list the corresponding
small steps from one or both year groups. Teachers
can then use the single-age schemes to access the
guidance on each small step listed within each
theme.
The themes are organised into common content
(above the line) and year specific content (below
the line). Moving from left to right, the arrows on the
line suggest the order to teach the themes.

Here is an example of one of the themes from the Year
1/2 mixed-age guidance.
In order to create a more coherent journey for mixed-age
classes, we have re-ordered some of the single-age
steps and combined some blocks of learning e.g. Money
is covered within Addition and Subtraction.
The bullet points are the names of the small steps from
the single-age SOL. We have referenced where the steps
are from at the top of each theme e.g. Aut B2 means
Autumn term, Block 2. Teachers will need to access both
of the single-age SOLs from our website together with
this mixed-age guidance in order to plan their learning.
Points to consider
• Use the mixed-age schemes to see where
similar skills from both year groups can be
taught together. Learning can then be
differentiated through the questions on the
single-age small steps so both year groups are
focusing on their year group content.
• When there is year group specific content,
consider teaching in split inputs to classes. This
will depend on support in class and may need to
be done through focus groups .
• On each of the block overview pages, we have
described the key learning in each block and
have given suggestions as to how the themes
could be approached for each year group.
• We are fully aware that every class is different
and the logistics of mixed-age classes can be
tricky. We hope that our mixed-age SOL can
help teachers to start to draw learning together.

In this section, content from single-age blocks are matched together to show teachers where there are clear links across the year groups.
Teachers may decide to teach the lower year’s content to the whole class before moving the higher year on to their age-related expectations.
The lower year group is not expected to cover the higher year group’s content as they should focus on their own age-related expectations.
In this section, content that is discrete to one year group is outlined.Teachers may need to consider a split input with lessons or working with children in
focus groups to ensure they have full coverage of their year’s curriculum. Guidance is given on each page to support the planning of each block.

Children read and interpret line graphs. They make links back to using number lines when reading the horizontal and vertical axes. Children can draw vertical and horizontal lines to read the points accurately. Encourage children to label all the intervals on the axes to support them in reading the line graphs accurately. When reading between intervals on a line graph, children can give an estimate of the value that is represented.
Here is a line graph showing the temperature in a garden.
Estimate the time when the temperature was 0°C.Estimate the temperature at 6 p.m.
This line graph shows the population growth of a town.
How can we use a ruler to support us to read values from a line graph?
Where do we see examples of line graphs in real life?
How is the line graph different to a bar chart? How is it the same?
How can we estimate the value between intervals? Does it matter if we are not perfectly accurate? Why?

Children use their knowledge of scales and coordinates to represent data in a line graph. Drawing line graphs is a Year 5 Science objective and has been included here to support this learning and link to reading and interpreting graphs.Children draw axes with different scales depending on the data they are representing. Encourage children to collect their own data to present in line graphs focusing on accurately plotting the points.
The table shows average rainfall in Leicester over a year.Complete the graph using the information from the table.
Here is a table showing the conversion between pounds and rupees. Present the information as a line graph.
On the rainfall graph, if the vertical axis went up in intervals of 5 mm, would the graph be more or less accurate? Why?
What scale will you use for the rupees on the conversion graph?
Which axis will you use for the pounds on the conversion graph? Explain why you have chosen this axis.
How can we use multiples to support our choice of intervals on the vertical axis?

Encourage the children to collect their own data and present it as a line graph. As this objective is taken from the science curriculum, it would be a good idea to link it to investigations. Possible investigations could be:• Measuring shadows over time• Melting and dissolving substances• Plant growth
Here is a table of data.
Which intervals would be the most appropriate for the vertical axis of the line graph?Explain your answer.
Rosie has used the data in the table to
plot the line graph.
What mistakes has Rosie made?
Can you draw the line graph correctly?
Rosie has plotted the time for 11:40 inaccurately, it should be closer to 160 than 120
She has mixed up the points for 12:20 and 12:40 and plotted them the other way round.

Children will present a range of line graphs over the year.
Children may give different answers but should give clear reasons. Intervals may range from 2s up to 10s. The most appropriate scale may be in 5s.

Children use line graphs to solve problems. They use prepared graphs or graphs which they have drawn themselves, and make links to other subjects, particularly Science.
Children solve comparison, sum and difference problems. They can also generate their own questions for others to solve by reading and interpreting the line graphs.
What was the highest/lowest temperature? What time did they occur? What is the difference between the highest and lowest temperature? How long did the temperature stay at freezing point or less?
How long did it take for the pulse rate to reach the highest level? Explain youranswer, using the graph to.help.What could have happened at 5 minutes?What could have happened at 7 minutes?
Estimate what the pulse rate was after 2 and a half minutes. How did you get an accurate estimate?
How does drawing vertical and horizontal lines support me in reading the line graph?
How will you plan out your own heart rate experiment? What information will you need to gather? What unit will you measure in? How will you label your axes?
Can we measure the temperature in our classroom? How could we gather the data? How could we present the data?

Carry out your own exercise experiment
and record your heart rate on a graph
like the one shown in the section above.
How does it compare?
Can you make a set of questions for a
friend to answer about your graph?
Can you put the information into a

Various answers.
Children can be
supported by
being given part-
drawn line graphs.
Here is a line graph showing a bath time.
Can you write a story to explain what is
happening in the graph?
How long did it take to fill the bath?
How long did it take to empty?
The bath doesn’t fill at a constant rate.
Why might that be?
Discussions
around what
happens to the
water level when
someone gets in
the bath would be
useful.
Approximately 9
and a half mins to
fill the bath.
Approximately 3
and a half mins to
empty.
One or two taps
could be used to
fill.

What is the same and what is different about the two graphs?
Here is a graph showing daily water consumption over two days.
At what times of the day was the same amount of water consumed on Monday and Tuesday?
Was more water consumed at 2 p.m. on Monday or Tuesday morning? How much more?
Children will build on their experience of interpreting data in context from Year 5, using their knowledge of scales to read information accurately. Examples of graphs are given but it would be useful if real data from across the curriculum e.g. Science, was also used. Please note that line graphs represent continuous data not discrete data. Children need to read information accurately, including where more than one set of data is on the same graph.
Where might you see a line graph used in real life?
Why is the ‘Water Consumption’ graph more difficult to interpret?
How can you make sure that you read the information accurately?

Eva has created a graph to track the growth of a plant in her house.
Eva recorded the following facts about the graph.
a) On the 9th of July the plant was about 9 cm tall.
b) Between the 11th and 19th July the plant grew about 5 cm.
c) At the end of the month the plant was twice as tall as it had been on the 13th .
Can you spot and correct Eva’s mistakes?
a) On the 9th July a more accurate measurement would be 7.5 cm.
b) Correct.
c) On the 31st the plant was approximately 28 cm tall, but on the 13th it was only 10 cm which is not half of 28 cm. The plant was closer to 14 cm on the 17th July.
Write a story and 3 questions for each of the 3 graphs below.

Create a line graph to
represent the information.
The table below shows the population in the UK and Australia from 1990 to 2015.
Create one line graph to represent the population in both countries. Create three questions to ask your friend about your completed graph.
Children will build on their experience of reading and interpreting data in order to draw their own line graphs.
Although example contexts are given, it would be useful if children can see real data from across the curriculum.
Children will need to decide on the most appropriate scales and intervals to use depending on the data they are representing.
What will the 𝑥-axis represent? What intervals will you use?
What will the 𝑦-axis represent? What intervals will you use?
How will you make it clear which line represents which set of data?
Why is it useful to have both sets of data on one graph?

Who has completed the graph correctly?
Explain how you know.
Rosie has completed the graph correctly. The car has still travelled 15 miles in total, then stopped for 15 minutes before carrying on.
This table shows the distance a lorry travelled during the day.
Create a line graph to represent the information, where the divisions along the 𝑥-axis are every two hours.
Create a second line graph where the divisions along the 𝑥-axis are every hour.
Compare your graphs. Which graph is more accurate?
Would a graph with divisions at each half hour be even more accurate?
Children may find that the second line graph is easier to draw and interpret as it matches the data given directly.
They may discuss that it would be difficult to draw a line graph showing half hour intervals, as we cannot be sure the distance travelled at each half hour.

Ron and Annie watched the same channel, but at different times. The graph shows the number of viewers at different times.
Ron watched ‘Chums’ at 5 p.m. Annie watched ‘Countup’ at 8 p.m.
What was the difference between the number of viewers at the start of each programme? What was the difference in the number of viewers between 6 p.m. and 8 p.m.? Which time had twice as many viewers as 6 p.m.?
Two families were travelling to Bridlington for their holidays. They set off at the same time but arrived at different times.
What time did family A arrive?
How many km had each family travelled at 08:45?
Which family stopped midway through their journey?
How much further had they left to travel?
Once children can read, interpret and draw lines graphs they need to be able to use line graphs to solve problems.
Children need to use their knowledge of scales to read information accurately. They need to be exposed to graphs that show more than one set of data.
At this point, children should be secure with the terms 𝑥 and 𝑦axis, frequency and data.
What do you notice about the scale on the vertical axis? Why might it be misleading? What other scale could you use?
How is the information organised? Is it clear? What else does this graph tell you? What does it not tell you?
How can you calculate ________?Why would this information be placed on a line graph and not a different type of graph?

Construct a pie chart using the data shown in this percentage bar model.
A survey was
conducted to show
how children in
Class 6 travelled
to school.
Draw a pie chart to
represent the data.
Pupils will build on angles around a point totalling 360 degrees to know that this represents 100 % of the data within a pie chart.
From this, they will construct a pie chart, using a protractor to measure the angles. A “standard” protractor has radius 5 cm, so if circles of this radius are drawn, it is easier to construct the angles.
How many degrees are there around a point? How will this help us construct a pie chart?

A survey was conducted to work out Year 6’s favourite sport. Work out the missing information and then construct a pie chart.
Children will then use this to draw a pie chart.
A restaurant was working out which Sunday dinner was the most popular. Use the data to construct a pie chart.
Miss Jones is carrying out a survey in class about favourite crisp flavours. 15 pupils chose salt and vinegar.
How many fewer
people chose
ready salted?
Children will then use this table to draw a pie chart.
15 pupils = 180˚
180 ÷ 15 = 12
12˚ = 1 pupil
72 ÷ 12 = 6 pupils
15 − 6 = 9
9 fewer students chose ready salted over salt and vinegar.

Children will apply their addition and division skills to calculate the mean average in a variety of contexts. They could find the mean by sharing equally or using the formula:Mean = Total ÷ number of items.Once children understand how to calculate the mean of a simple set of data, allow children time to investigate missing data when given the mean.
What would the total be? If we know the total, how can we calculate the mean?
Do you think calculating the mean age of the family is a good indicator of their actual age? Why? (Explore why this isn’t helpful).

The mean number of goals scored in 6 football matches was 4.
Use this information to calculate how many goals were scored in the 6th match:
Three football teams each play 10 matches over a season. The mean number of goals scored by each team was 2.
How many goals might the teams
have scored in each match?
How many solutions can you find?
As the mean is 4, the total must be
6 × 4 = 24.
The missing number of goals is 3
