Have you used Plickers? It is such an awesome educational app, which functions as Clickers (student response system) without using any special equipments.
Although the app is awesome, students may struggle to use Plickers' cards to indicate their responses. That's why I created this package! This package contained redesigned Plickers cards with larger letters for easier identification.
Especially for young learners, it is hard to know which letter they are showing, as there is no indication on the back of the card. So, I have designed the backside of the cards, which shows letters which match with the front of the cards.
With this package, even young learners, as little as kindergarten students can participate in engaging learning activities, using Plickers.
