Standards alignment

Sumdog’s in-game questions cover standards for K-8. The games complement teacher-led lessons or instruction to reinforce learning or offer extra support at school or home for areas that need improvement.

Sumdog works!

A recent study demonstrated that using Sumdog for just 30 minutes a week almost doubled children’s fluency growth. With Sumdog, you can easily see student activity at a glance and the powerful diagnostic tool enables you to quickly identify strengths and areas for development.

An instant hit!

“After the first day of using the program, I knew it was an instant hit. The next day my students were eagerly asking, well, begging really, to use the program again.”
Sherri Oliver, Teacher, Mount Vernon Community School, VA, USA

A great educational game!

“This program targets several objectives at one time. My ELD students are the ones that are benefiting from it the most - they are spelling, listening and writing all in one game. This is a great educational game.”
Noemi Escalante, Teacher, Clawson Elementary School, AZ, USA
“Sumdog's mission is to narrow the achievement gap - by helping every child reach their full potential.”
