One way we've been doing this is through a chart I've created. I found this image from lifehacker.com that clearly categorizes most emotions under each of the above categories.
I then transferred the emotions to a homemade chart I made using images from a Google search. Here's what I came up with.
I printed the lifehacker chart on the back of the page and laminated the sheet. So now, when my kids are having difficulty expressing their emotions, we can go to the chart and work through how they're feeling until we have identified it. It has helped with overall communication and lessened the number of breakdowns because we can calmly point to pictures instead of
I hope that you are able to use this as a tool in your home or classroom as a way to help your children identify their emotions.
