I created this grammar review quest based on my students asking me to help them review problem areas, things like using commas, punctuating dialogue, and your/you're.
I've made the quest differentiated so if students do poorly on a quiz, they will be redirected to another one on the same subject. I started making this quest before they connected the quests to Classroom where I could have just made a Google Form for these, but I am just going to have students screenshot and email me their results in order to progress in the quest.
I've spent roughly 7 hours on this and used the Mage island as my setting. Let me know what you think!
