SCITT Session 9 Solving problems involving Statistics Objectives (students will): be able to plan progressive activities in data handling; use the Data Handling Cycle in the classroom;
be aware of the key role of ICT in analysing and representing data. 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. Mathematical Language count sort order set match pictogram Venn Diagram

maximum minimum Sorting Diagrams Numbers 1-20 (inclusive) How could we sort these numbers? One set criteria? Create a two-criteria Venn Diagram Venn & Carroll Diagrams
How do these diagrams match up? 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 largestthe middle value.
What types of data? Primary children need a range of data representations (Matching activity) Which examples have you seen in your classroom? Discrete or Continuous? What is the difference between discrete
and continuous data? Discrete data Categorical Data data collected by counting and grouped into categories which are not linked. The
categories cannot be ordered. Continuous Data Continuous Data. Data collected by measurement.
The variable can take on any value on a continuum and all values have meaning. NC2014 expectations Read the expectations for your year group
and one year either side Identify the aspects that you have already seen talk about any different examples. What suggestions from NCETM? Read the article and follow any suggested links Year 6 - Today we will read and interpret bar graphs
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 Less than altogether
