Subtraction Tables help children with the memorization of the essential equations of subtraction!

Children can practice individual subtraction sets, such as 7-1, 7-2, 7-3, etc. The child can fill out the cards in any order they choose and can do so using the automatic or drag & place method.

In a subtle way, the app keeps track of the child's progress, with a score or a timer, so parents and teachers can review their activity. Children can cycle through multiple cards that are randomized within each number set. Included is a set that includes randomized cards drawing from all the number sets (1-18).

This activity is a time-tested method of reinforcing the basic differences of subtraction and is used in Montessori classrooms around the world! This app was co-developed and approved my an AMI certified Montessori teacher with over 40 years experience in the field!

Lil disappointed

These apps are amazing as a reinforcement tool, however disappointed with the subtraction table. Not practical for teaching math facts. For example the 1s table only displays 1-1 n 2s table only does 2-2 n 2-1 n so forth. Would be better if it displayed 10-1, 9-1 then 10-2 n 9-2 etc., can this be address and updated. These apps are expensive whether purchased individually ($2.99 - $3.99) or as a bundle ($12.99) to only have one fact in the 1s table n two facts in the 2s table.
