Is there a way to print all the answer keys to the activity guides in one place without going through each individual lesson? For example, I see where you can print all the lesson plans or all the handouts for an entire unit. Is there a place to do this for the activity guide answer keys/exemplars?
No, I don’t believe there is. You can see all the exemplars in one “place” if you click on “Go to Unit”, then click the blue button “Teacher Resources”, then choose “All Resources” from the dropdown. This does save you from opening each lesson plan separately to print the Activity Guide Exemplars.
That is a good suggestion. You might consider submitting it to https://support.code.org/.
