I spent about ten minutes making a comic strip. I was able to manipulate the positions of the characters, add text and accents, and a cool background.
There is an educational version as well as a for fun account. (There is a 30 day trial, so if you are going to use it that way, make sure you get it when you need it so you don't lose the opportunity.) The for fun account posts the work on the web, so if you have students who do not have permission to post work online, don't use it, or print off a blank template and have the kids fill it in. I created the for fun account. It is free. The educator account is based on the number of kids. I have 9 students, so for me, it isn't worth $60/ year. I can add up to 20 kids for that price, but it isn't worth it to me. I see myself using it but not often enough to justify the cost.
Here is my quick comic to review lesson 1 in French 2: Quick and simple, and a great model for my kids. I think this program is very good for foreign language teachers. I also think it could benefit elementary teachers to address writing skills and it could be used as a means of identifying incorrect grammar. One could have grammatical or spelling errors and ask students to identify them. That is a way to make grammar fun.
So, if you are looking for a simple way to practice writing and do so in a funny and creative manner, check out Pixton. It is something different for your classroom.
