How I Use It
I use SumDog as an extension activity for math practice in my computer lab. When students finish their lesson for the day, they are allowed to log in to SumDog and play. They love the different games! It's especially great for younger kids, who have more patience for "learning" games. It does require a log in, which might be tough for K-1 students. SumDog automatically generates little log in tickets for each student, which is great, but the tickets and writing are very small and are hard to read sometimes.
The teacher can choose the grade level the students work on. As questions are answered correctly, students get coins to spend in the store. By default, the store is "closed" during the school day and can only be used after school or on weekends. This is a great feature that I wish other sites would implement (e.g. RAZ-Kids)!
SumDog is a great site for kids to practice what they are learning in math. The games are all different and interesting. There isn't much language on the site, but I wish there were different language translations. That would help some of our English Learners. Also, this site doesn't teach any math concepts, it's merely practicing what students learn in the classroom. But as a way to motivate and reward students, it's a great site to use. Plus, one of the best features is that it's free! There are a few premium games, as well as reading and writing games, that require a subscription (inexpensive). Most of the site, the teacher managing features, and the games, are free!
