One little fellow I have is so excited. He is getting to play the same games others are playing. However, he is being successful and having a much higher accuracy rate than he has seen all year with any assessment. I can not stress enough the motivation Sumdog provides – this is its strongest asset compared to other programs.

I was able to differentiate through the skills-based challenges and assign different ones to students who struggle with prior skills that we have covered in class. This has allowed them a different avenue to continue their learning through practice and engagement. Students were able to build on these skills at school but also at home through a fun and safe site that parents can trust.
