# Motion Math: Fractions!

- estimation
- fractions

- part-whole relationships
- thinking critically

###### Pros

Provides a fun and innovative way for kids to learn fractions; multiple levels appeal to kids with varying abilities.###### Cons

Continuously tilting the device to play the game can become tiresome.###### Bottom Line

Kids will find this a fun and creative way to learn about fractions.None

Novel concept of bouncing a star on a number line is fun and will draw kids in. More gameplay variety could keep them interested longer.

Using both graphic and numerical representations helps kids visualize and develop strong fraction sense. Feedback provides opportunities for kids to learn from their mistakes.

An instruction screen clearly explains how to play the game. Introductory level shows students how to tilt the device to move the star.

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.

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.

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.

4.NF: Build Fractions From Unit Fractions By Applying And Extending Previous Understandings Of Operations On Whole Numbers. | |

4.NF.3.a | Understand addition and subtraction of fractions as joining and separating parts referring to the same whole. |

4.NF.3.b | 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. |

Extend Understanding Of Fraction Equivalence And Ordering. | |

4.NF.2 | 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. |

Understand Decimal Notation For Fractions, And Compare Decimal Fractions. | |

4.NF.6 | 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. |

3.NF: Develop Understanding Of Fractions As Numbers. | |

3.NF.2 | Understand a fraction as a number on the number line; represent fractions on a number line diagram. |

3.NF.3 | Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size. |
