Are your students struggling to decide when to use this, that, these, and those? This hands-on activity to practice demonstratives will help your students use context clues and pictures to get practice using this tricky grammar.
I suggest having a grid on the whiteboard where students can mark off when they're finished with a card. My elementary school (and some middle school!) students in Taiwan enjoyed the healthy competition. Plus, it gave them speaking practice.
Overall, if you need a whole class engagement activity, this set of clip cards will suit you well.
This set includes 8 clip cards to get you started.
