I created this resource to re-teach primary and secondary sources.
I have two slides defining each. Then, I have a slide comparing and contrasting first and second hand accounts. I would have students complete the Venn Diagram first, and then show the answers after.
Next, I have 11 slides for interactive practice. At the end, there are questions for a pop quiz. I would suggest using this slide as a check for understanding.
I hope you enjoy the product!
