ABSTRACT

At the middle school level, students solidify, extend, and apply their understanding of our number system. Students develop computational strategies based on the properties of these operations established in the elementary years. Over seventh and eighth grades, students convert between rational and decimal number representations and in eighth grade, students are introduced to irrational numbers. Different representations of an equivalent fraction, decimal, and percent make a match. Estimation skills are essential; we probably use them every day. Teams must then find three numbers on the game board to use in an expression with a value equal to the target number. Additional points are scored if the numbers chosen are adjacent on the board, which encourages students to consider a variety of options. Helping students develop a precise mathematics vocabulary is important, as an inadequate academic vocabulary can negatively impact content knowledge.
