Rebecca Thal found Sumdog Maths:

• Significantly improves attainment“I not only use Sumdog to reinforce skills my students are currently working on, but I also use it to spiral back and review skills previously taught in the school year.”
• Significantly builds student knowledge“I am able to personalize instruction and give different groups of students different skills to work on, depending on their individual needs.”
• Significantly reduces teacher workload“Tell students and teachers which answers were correct and incorrect - in games and assessments.”
