Use the game as a way to introduce fractions or reinforce learned concepts. Since multiple users can be registered on each device, kids can work in small groups, taking turns completing a level. Discuss results as a class and ask students how the game helped them develop an understanding of fractions. Kids can repeat the level after a more formal classroom lesson and compare their new scores to their original scores.Continue reading Show less
Gameplay is simple, yet effective. Kids choose from three levels of difficulty; at each level, games get more challenging as play progresses. Games start with a star containing fractions written in standard form –- numerator over denominator. Kids tilt the device so the star lands on the matching area of a number line. For example, if the star contains the fraction 2/3, kids have to land the star on the number line so it shows two-thirds. As games progress, students are given different representations of fractions including decimals, percents, and pie charts. They earn points and star rewards for correct answers. Multiple players can be entered on a single device, and high scores are tracked.
Motion Math: Fractions! is an innovative game that teaches kids about fractions while covering a handful of Common Core math standards. Through the use of such visuals as number lines and fraction bars, students can learn how to estimate and compare fractions in various formats including standard, decimal, percent, and pie-chart.
Games are highly interactive but could use a bit more variety. Kids have to tilt the device to bounce the star so it lands on the correct place on a number line. If they get an answer wrong, feedback is progressive and highly effective. First, a directional arrow appears to help kids aim the star toward the correct area of the number line. Next, tick marks appear on the number line to show the fraction's denominator. On the third attempt, equivalent fractions are given for comparison. Finally, an arrow points directly to the correct place on the number line. The scaffolded feedback and clear visual representations are sound methods for helping kids develop fraction sense.
Key Standards Supported
Number And Operations—Fractions
Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.
Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.
Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
Understand a fraction as a number on the number line; represent fractions on a number line diagram.
Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
