This is a project that I (Warith) started to help students practice for Number Sense competitions, geared towards HS students preparing for the UIL State Championship hosted by UT Austin in May.

Number Sense is a competition developed by the University Interscholastic League (UIL) to test students on their mental math. Students are given a 10-minute time limit to answer as many of 80 problems as possible, under the following scoring conditions:

• +5 points for every correct answer
• -4 points for every wrong answer
• -4 points for every question skipped
• Unanswered questions after the last attempted question are not penalized

Yes, yes it is. However, many tricks have been developed to turn basic arithmetic that may take 30 seconds mentally into a quick 5-second process. That's the purpose of this project! Using the Bryant Heath Manual and NS Sequencing Guide as guidelines, my goal is to try to develop this open-source website as one to help students grow as much as they can in their mental math abilities although of course hopefully non-Allen people don't discover this until later...
