Understanding fractions is extremely important and predicts later success in high school mathematics. For this reason, we developed a suite of game to teach and assess students’ fractions knowledge. Teachley Fractions Boost, Boost 2, and Fractionators cover 3rd - 5th grade fractions standards.
In this study, students in grades 3-5 were randomly assigned to play either Teachley Fractions games or Slice Fractions games for six weeks. The students playing Teachley games developed stronger estimation skills in placing single fractions and the results of fractions operations on a number line. The 3rd graders playing Teachley outperformed the control group 5th graders at posttest.
