Zearn Math review

Zearn Math is the most research-backed free option on this list, and the one to choose when a child needs lessons that track what their class is doing. The nonprofit says its entire content library is free so families can see what students are learning, and free teacher accounts cover up to 35 students and 1 teacher. Each lesson starts with fluency activities for math facts, moves through guided instruction with pictures, objects and digital manipulatives, and includes prompts for paper-and-pencil problem solving. When students struggle, lessons adapt in real time with support while keeping them on grade-level work, and students must show full understanding before moving on. Zearn reports a randomized trial of more than 10,000 students and a Strong (Tier 1) rating from Evidence for ESSA. It ranks sixth because it is built for structured classroom use and plays less like a game, so it may need an adult to set up and guide it at home. We compared documented features and published prices only.
