Happy Numbers is an online platform that helps teachers deliver differentiated math instruction to PK-5 students. Teachers can sign up, add their class, and share this resource with students. Each child will take a placement test to help tailor the math instruction to their individual needs. Students can work at their own pace, but the creators of this program recommend for students to work on the lessons for 15 minutes 4 days a week. Happy Numbers is offering teachers free access through the end of the school year to help kids continue to learn at home.
