Reviews and Endorsements:
Fun Educational Apps:
“iDevBooks educational math apps make math enjoyable and entertaining. One of my sons was struggling with math and I must say the use of iDevBooks math apps has really helped him.”
Professor Tim Pelton reviewed the sister app Column Subtraction:
“Because no wrong entries are allowed the app provides a passive form of positive reinforcement and your child will likely improve in both confidence and competence with respect to the procedure.”
Teacher endorsement:
“The Math apps by Esa Helttula allow students to practice and reinforce the specific computation strategies taught in class, with as much or as little scaffolding as necessary. They also provide individualized feedback to each student, with an immediacy that is not always possible through pencil and paper practice.”
— Rita Zeni, Ecole Sandy Hill Elementary, Abbotsford, BC, Canada
