Fact Triangles

About this app

Part of the Math Practice Tools CFS Bundle Practice math facts 1-12 using Fact Triangles. Set the problems to practice in sets of 5, 10, 20, or 25. Practice all facts by selecting the addends or factors from 1-12 or focus on these sets (2, 3, 4); (5, 6, 7); (8, 9, 10); or (11, 12). The iPad version allows making choices for both addends and both factors. • At the request of Kindergarten and First Grade teachers, added option to create problem sets with Sums 1 to 5 and Sums 1 to 10. Also included options for Sums 1 to 20; Sums 5 to 10; Sums 10 to 15; Sums 15 to 20; Sums 10 to 20. The sum or product is always placed at the top of the triangle. But, the fact family member you must identify can be any of the three members. Feedback is provided as each problem is attempted. After each set of problems is completed, the total number correct, missed, and the time used to complete the set are displayed. On the iPad version you'll see all of your problems and answers. On the iPod version, you can see up to 11 correct and 11 incorrect responses. Sound effects are set to off as default.

• Updated to support iOS12 - thank you for your patience. • A few other minor tweaks • As time allows, I'd enjoy hearing how you're using this app in the classroom and at home.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
