The presentation provided enough information for students to understand the problem to the pretend story. The skill that this activity is having students practice is scientific reasoning and deduction, which will be easiest to do with printed paper but if that’s not an option there is a button for each resource to “copy student editable version” into a google drive so that students can edit the file digitally. It is easiest to have students follow the video step by step for the activity because Doug provides a good explanation of the clues.
