I've used this and similar posters in my ESL classroom to help my students add these adverbs to their memory bank.
It helps to give them a simple way to gauge their emotions as well. For example, if a student says, "I am happy.", then I almost always immediately ask, "How happy are you?".
This poster can also be a handy as a handout to add to a student's take-home file for a memory refresher or to help with homework.
For other handy ESL resources, check out these CVC phonics games. These are free samples, but I'm confident that if you give them a try in your classroom, you'll be back to check out the expanded bundles too!
