When reading multiple sources, noticing the author’s purpose can help a student 1) remember the content of the source and 2) begin to notice the similarities and differences between sources.
I’ve created a Padlet with a text set on recycling – one for each type of author’s purpose (e.g. P.R.I.D.E.) (4th-8th grade). Please feel free to copy the Padlet. It would be easy to take away the labels for PRIDE so that students can explore the sources and identify for themselves the different purposes.
For more information on introducing author’s purpose, check out this blog.
For more ideas on how to teach with multiple sources (including putting together text sets), check out my book Nurturing Informed Thinking.
Hope this helps.
