Strand 6 of the Revised Primary School Curriculum examines Data and Stand Unit 6:1 focuses on Representing and Interpreting Data. In 5th and 6th classes pupils should be able to collect, organise and represent data using a variety of charts ranging from simple pictograms to more complex pie-charts. Currently the National Council for Curriculum and Assessment (NCCA) are re-presenting Mathematics Skills and Objectives on their website and of course Data is an important part of that re-presentation.
Although many teachers introduce their pupils to the charting wizard in MS Excel to produce data charts through ICT integration with the Maths curriculum, I thought it might be of interest to look at three Web 2.0 tools that can assist pupils to present their data in chart format.
Taking a step back for a moment – the term Web 2.0 is associated with web applications that allow the sharing of information and subsequent collaboration on the Web.
The first two tools – Richchartlive and Charts.Hohli produce effective charts and both site are well worth checking out. However my own favourite is Chartle.
What follows is a brief walk thru in the creation of a pie-chart using Data collected by pupils on how they come to school each day.
Step 1 – Go to the website and Click on the “create your own“ link.
Step 2 Select your chart type – here I selected Pie-Chart
Step 3 Click on the Data Tab and then edit the contents to reflect the data collected. We had four data entries, Walk, Bus, Cycle and Car. Segment colour can also be edited here. 
Step 4 Click on the General Tab to edit the Chart title and other text attributes.
Step 5 Click on the Publish, Share or Embed button to view your completed chart.
Step 6 Copy the HTML code and paste into a page on your school web site or blog. 
There are several charting choices that are not relevant to the Primary Curriculum; however the tool is really easy to use and it produces great charts!
