9-year-old Nephew is about 2 years behind grade level. si U want to use these cards to show him how to add and subtract and then multiply and divide.

I started making our own triangle flash cards to display the relationship between fact families (addition/subtraction and multiplication/division) and then I saw these. They'll work great!

As a former retired teacher I know these cards work! Combining these with Common Core will make calculations faster.

My granddaughter needs reinforcement with fact families. These cards were very helpful when working with my nephews. Any child can learn to practice by themselves.

It was linked from my student's school. It looks like a useful tool for learning math facts.

I expect these cards will help my daughters internalize the connection between the three numbers instead of separating the numbers.

Hoping to help my daughter with her speed on math facts, as she is very right-brained and really doesn't have much interest in memorizing facts or being timed on them as she is at school.
