be aware of the key role of ICT in analysing and representing data.

3. Associated issues for teaching
Consideration of primary and secondary data;
Evaluating and interpreting current information by posing appropriate questions;
Key starting points for estimation;
Mathematical questions – how to promote and recognise rich questions.

Handling data
How long is the piece of string?

10. What types of data?
Primary children need a range of data representations…
(Matching activity)
Which examples have you seen in your classroom?

11. PNS expectations
Read the PNS progression for your year group and one year either side
Identify the aspects that you have already seen… talk about any different examples.
Are there any aspects yet to cover?

12. To do… 1. Work together to annotate the graph to help you read it.
2. Take it in turns to brainstorm 10 facts about the data presented.
3. Predict the questions… how many can you think of?
4. Share ideas with one other pair from your group.
Here are some words that you might like to include in your facts (or your questions) about your graph…
Fewer most more least

13. How long is a piece of string?
Average
How long is a piece of string?
Mean Add all the values together and divide by the number of values.
Mode The most common value.
Median Order the values from smallest to largest…the middle value.
