In this four-day lesson students use several models to explore equivalent fractions and to compare proper fractions with denominators of values up to 12. It incorporates the book "The Hershey's Milk Chocolate Bar Fractions Book" by Jerry Pallotta. The 30-page pdf includes lists of materials, teacher instructions, printable activity sheets, assessments, and a game. | Activity, Lesson Plans Grade Level: 3, 4, 5 | |

Teachers can use this interactive tool to help students make sense of equivalent fractions by linking visual models to words and procedures. Students learn the value of multiplying a fraction by a fraction with a value of one. This page includes a video demonstration of the tool and sample lessons from the Conceptua curriculum. Free registration is required to use the tool. A paid subscription is necessary to access full curriculum and allow full student use. | Activity, Demonstration, Interactive Media, Video Grade Level: 3, 4, 5 | |

This iOS app ($) provides students with practice and reinforcement of fraction concepts in a solitaire context. Users try to clear a board by matching cards displaying equivalent visual and numeric representations of fractions, while getting feedback and scoring points for accuracy. A tutorial with voice explains how to play. | Activity, Game, Interactive Media, Mobile App Grade Level: 3, 4, 5 | |

This interactive Flash game challenges students to specify a location as a fractional part of a unit segment. Grampy hides (partially) behind a hedge, and the student enters the numerator and denominator of a lowest terms fraction that locates him. Instructions are provided below the applet; practice with renaming fractions and an easier version of the game are found elsewhere at the site. | Activity, Interactive Media Grade Level: 3, 4, 5 | |

Students can use this Shockwave applet to learn basic probability concepts and to apply fraction and decimal skills. In Level 1 a number of fish are seen in a tank and users express the probability of catching a red fish as a fraction. In Level 2 the required probability is given as a fraction, and users move more fish into the tank to produce this probability. Level 3 is similar to level 2 but involves a wider range of fractions and some decimals. The Key Ideas page provides background in basic probability concepts. A set of student activity printouts (Probability) is available for further practice. | Activity, Game, Interactive Media Grade Level: 4, 5, 6+ | |

This is a sample PARCC assessment task based on CCSS grade 3 fraction standards. In this interactive three-part task students reason about fractions used to represent area or a location on a number line. Included are the alignments to the CCSS, a scoring rubric, and background on the task itself. | Assessment, Problem Set, Reference Materials Grade Level: 3 | |

In this interactive shockwave game, students match equivalent fractions by making fraction pairs. During each round, the student receives more cards with greater difficulty of fraction equivalencies to match, all while being timed. The goal is to beat the time and get as many correct matches as possible in order to get the highest score. | Game, Interactive Media Grade Level: 3, 4, 5 | |

This interactive game provides an opportunity for students to think about how fractions are related to a unit whole, compare fractional parts of a whole, and find equivalent fractions. Players move markers a total distance that is less than or equal to the random target fraction, along their choice of seven parallel number line tracks, which are divided into different fractional parts. The goal is to move each of the seven markers to the right side of the game board using as few fraction target cards as possible. Instructions and exploration questions are included. | Activity, Game, Interactive Media Grade Level: 3, 4, 5 | |

This FAQ page from the Teacher2Teacher service at The Math Forum @ Drexel contains many suggestions for learning about fractions.
