The online National Math Bee tournament uses our Batter Up platform to test students’ speed and accuracy in the four basic math modes, addition, subtraction, multiplication, and division. The Batter Up tournament points system was developed and tested in the study “Automaticity of Basic Math Facts With a D&P ILS Using Various Grouping Combinations in Elementary School Classrooms” by Dr. S. David Vaillancourt.
Tournament scores, how are they calculated?
So you may be wondering, how does the Batter Up game point system calculate each student’s batting average (score) to rank them in the tournament?
The following information has been taken directly from the Research Study done using the Batter Up game.Developed by Dr. S. David Valliancourt.
The tournament points system is based on improvement in automaticity as demonstrated within the ILS practice/play. The measurement of automaticity is accomplished with the system identified below:
1.) Base Hit Times
The base hits are determined by a chart of ‘Base Hit Times for the (Addition, Subtraction, Multiplication, or Division) Facts’ developed through a pilot implementation of the game in elementary schools.
2.) Point Values per Hit
Point values are assigned according to the league level in which the ‘base hit’ is accomplished as identified on the chart below:
3.) Batting Average
Batting Average (BA) is calculated as follows: BA = points (table above) multiplied by .142857, then divided by times at bat and rounded to the nearest thousandths.
BA is calculated per mode (addition, subtraction, multiplication, etc.) only. A student’s BA in one mode does not affect the same student’s BA in another mode.
4.) Automatic Level Assignment
Automatic Level assignment is calculated as follows:
- If BA in identified mode is < .429, then assign to Little League.
- If BA in identified mode is < .429 but > .642, then assign to Minor League.
- If BA in identified mode is < .642 but > .785, then assign to Major League.
- If BA in identified mode is > .785, then assign to Hall of Fame.
