One idea I have applied this year per unit is keeping every QR code I use in class (videos, interactive activities, questions,...)
with all these QR codes they use autonomously we create a mini book and when we have tablet - time they can remember other topics we have already learned or just learn new ones.
I share some examples of QR CODES...

SOMETIMES, I do a QR GYMKANA I share the sketch. the idea is to scan the QR CODES and then answer the questions. They do it in cooperative groups.
