Resources and Tools for Elementary Math Specialists and Teachers

Common Core State Standards for Mathematics

Grade(s) 6 resources related to the following standard:
Ratios and Proportional Relationships
Understand ratio concepts and use ratio reasoning to solve problems.
2. Understand the concept of a unit rate a/b associated with a ratio a:b with b ? 0, and use rate language in the context of a ratio relationship. For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger."

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.

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.

This lesson provides an opportunity for students to develop concepts and skills with fractions, decimals, and percentages in the context of shooting baskets. Students take turns tossing a ball into a wastebasket a number of times determined by a random card draw, while other students keep track of the number of shots made. The class processes the data by creating fractions and converting them into decimals and percentages, and then uses them to analyze and interpret the results.

Villainy, Inc. is a website devoted to helping upper elementary grade students build and use problem-solving skills to solve unique and complex mathematical problems. Students become undercover agents working to thwart the evil Dr. Wick, ID and his often-zany schemes to take over the world. Student activities include finding areas of rectangles, calculating with decimals and percents, finding averages, estimating and comparing whole numbers and decimals, all presented in the context of an animated and interactive cartoon story. Students complete one or both of the missions online. Teachers editions for each mission are provided, as well as additional tips, answer keys, printable worksheets and connections to standards. Note that it is not possible to save work online.
