In this interactive game, students use their knowledge of multiplication, division, factors, ratios, and proportions in order to determine the correct amounts of each food to be fed to the monsters. The game allows players to play at the beginning level which provides twenty-four tries to fill in twenty portions of food, with four portions given to start. The monsters give hints if an incorrect portion is given. Students may play additional levels of this game at the Lure of the Labyrinth site to which users are directed at the end of the round. | Game Grade Level: 5, 6+ | |

In this 8-page article (PDF) Kastberg and Frye explain how sociomathematical norms can improve students' mathematical proficiency. The article focuses on a 6th grade class working through a ratio comparison problem. In this classroom students had been encouraged to question and challenge their own solutions as well as peer's solutions, leading to deeper mathematical understanding through valuing the differences in problem solving and reasoning. | Reference Materials, Article Grade Level: 3, 4, 5, 6+ Resource is part of a PD collection | |

In this game, students navigate a maze to get to a math challenge. The three challenges are: move blue and green "fuel cells" around to match the ratios in the given containers; measure shapes to determine the scale factors needed to make them match the given templates; determine how to place bases on a map based on clues involving proportions. | Game Grade Level: 5, 6+ | |
