Review by professor Tim Pelton

Tim Pelton, assistant professor of Mathematics Education at the University of Victoria:

“If your goal is to help your child to master the traditional subtraction algorithm then Column Subtraction may be the ideal App.”

“With the ‘show current operation’ option turned on, they are constantly reminded of the next step, which can lead to efficient practice of the procedure. Then by turning off the current operation your child is able to practice remembering the steps on his/her own. 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.”
