This interactive applet helps students develop fraction sense by comparing and ordering fractions and identifying equivalent fractions. In each of 8 progressive rounds students arrange 10 socks, each with a fraction displayed, onto a 0 - 1 number line by estimating their relative locations. The applet adjusts the position of each sock to be accurate; however, if the new sock has to pass a previously placed sock, the level ends and the player must start over. | Activity, Interactive Media Grade Level: 3, 4, 5, 6+ | |

In this lesson plan, students investigate ways to share different sized items between two people. Students are asked to find equivalent fractions on a number line and to order those fractions by size. Included are a video clip called Equal Amounts of Gold, two worksheets, and two assessments as well as an answer key. | Activity, Lesson Plans, Video Grade Level: 3, 4, 5, 6+ | |

This webpage contains a 6-minute video that shows Cara Crist working with her third grade class to create fraction strips (wholes, halves, fourths, and eighths). The students use these fraction strips to play a game of "Cover Up" where they must cover the one whole using the other fraction pieces. Crist discusses how this can be extended to "Uncover" and "Trade Up" versions of the game. This webpage also contains a PDF link that details how to play "Cover Up" and "Uncover". | Activity, Game, Video Grade Level: 3, 4 | |

This is a sample PARCC assessment task based on CCSS grade 3 fraction standards. In this interactive five-part task students reason about fractions used to represent part of a whole 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 | |

This lesson gives students practice in applying fraction concepts, interpreting positional words, and paying attention to details. In order to decode a message, students construct new words by using fractional parts of other words as specified in the clues. A correct analysis of the clues leads to a candy bar reward. The activity could be adapted to accommodate individual classes and situations. | Activity, Lesson Plans Grade Level: 3, 4, 5 | |

In this interactive game similar to Concentration(TM) students match fractions (1/2, 1/3, 3/4, and 5/9) to images that represent those fractions. This game can be played in pairs with the printed out cards or as a whole class on the interactive white board (IWB). This resource includes teacher notes with suggestions for introducing the game, discussion questions, support suggestions, a set of cards to be printed (PDF), a blank set of cards to make your own (PDF), and a full screen version of the game. | Activity, Game Grade Level: 3, 4, 5 | |

This document provides descriptions and examples of what each Mathematics Common Core standard means a Grade Three student will know, understand and be able to do. This "unpacking" of the standards provides instructional guidelines and was developed to assist North Carolina educators teach the Mathematics Common Core (Standard Course of Study). | Reference Materials Grade Level: 3 | |

In this interactive game users match Melvin's potion bottles by choosing equivalent fractions. Users can match the fraction number to the equivalent fraction picture, the fraction number to another equivalent fraction number, or the fraction picture to another equivalent fraction picture. The user is given a correct or incorrect response from Melvin. The goal is to match the bottles in each round in order to go onto the next round where there are more bottles and more variations of equivalent fractions. | Game, Interactive Media Grade Level: 3, 4, 5 | |

This interactive Java applet allows users to explore rotations and composing shapes by selecting various shapes to place on the drawing board, then moving and rotating them. There are many other possibilities for instruction including fractions, patterns, ratios, tessellations, symmetry, patterns, and perimeter. Shapes which can be placed on the board include equilateral triangles, isosceles trapezoids, regular hexagons, rhombuses, and squares. Pieces and groups can be cloned, and the colors can be changed. Their dimensions allow them to tessellate easily. | Activity, Interactive Media Grade Level: K, 1, 2, 3, 4, 5 |
