I thought I would start of 2018 with something fun, quick, easy to play yet still educational activity.
Many people, including native speakers struggle with where to put the apostrophe in the word its (I know that is wrong but I wanted to write it without any apostrophe).
Pin the Apostrophe on the Its is a great game to play with teenagers and adults, as a reward or warmer or even review.
All you need to do it blindfold them, you can even spin them around a few times, and have them touch the screen (you will need an interactive whiteboard) to place the apostrophe where they think it will go. The chances of them getting it correct are slim, but it still makes for a fun game.
