What is the idea behind The SumThingsUp Challenge?


An innovative contest in its inaugural year, the SumThingsUp Challenge encourages teachers and their students in grades 3, 4, and 5 to develop engaging and entertaining video lessons for key concepts in the math curriculum.  Participating teachers will design inquiry-based modules for their students, and then (with the teacher's help), the students will create a short video lesson designed to teach and explain the concept to students in other classrooms and schools.  There will be a contest question/concept for each grade, and each participating classroom will be competing for classroom prizes.  
There will be two separate sets of judges.  The student-produced videos will be judged by a committee of Math Coordinators, Math Coaches, and Master Teachers AND by students themselves.  The SumThingsUp Challenge will offer 1st, 2nd, and 3rd place prizes of $500, $250, and $100, respectively, in each of the three grades.
This inaugural contest is being conducted with the cooperation of the Central District of the Los Angeles Unified School District.
