Motion Math HD follows a star that has fallen from space, and must bound back up, up, up to its home in the stars. Moving fractions to their correct place on the number line is the only way to return. Motion Math gives learners a physical experience of the number line and an intuitive feeling for fractions. Fractions are a notoriously difficult area and if a learner never gains a gut sense for them, it can impede progress in more advanced forms of math. One reason fractions are tough is that they can be written in so many different ways! Motion Math helps learners perceive and estimate many representations -- numerator over denominator (1/2), percents (50%), decimals (.5), and even pie charts.
Motion Math was inspired by embodied cognition, research suggesting that connecting one's body to abstract concepts can deepen understanding. By estimating each problem with its distance on the number line, learners can develop a fast, accurate perception of fractions.
