Circle Packing 1: Soda Cans
ORC# 7609
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Grades: Grades 9–12
Professional Commentary: Soda cans are often packaged in rectangular arrays, but more efficient arrangements that require less packaging material are possible. In this first lesson (in a unit of three), students investigate various designs for packaging soda cans and use geometry to analyze their designs....

Improving Mathematics Education: Resources for Decision Making
ORC# 5292
Resource Information
Resource Type: Professional Resources
Discipline: Mathematics
Grades: Grades K–Postsecondary
Professional Commentary: The mathematics that students need to learn today is not the same mathematics that their parents and grandparents needed to learn. When today's students become adults, they will face new demands for mathematical proficiency that school mathematics should attempt to anticipate....

Shape Pan Balance
ORC# 3642
Resource Information
Resource Type: Content Supports
Discipline: Mathematics
Grades: Grades 5–7
Professional Commentary: This site features an interactive pan balance that allows students to place shapes of unknown weights on either side of the balance as they try to determine the relationships among the weights. This activity illustrates a problem with multiple solutions, while it reinforces the notion of equivalence....

Predicting Patterned Behavior
ORC# 10179
Resource Information
Resource Type: Content Supports -- Activities and rich problems
Discipline: Mathematics
Grades: Grades 9–12
Professional Commentary: Students complete a triangular array by inserting numbers into the top row and adding pairs of numbers for subsequent rows to achieve a final sum at the bottom. After discovering that the position of a number in the top row affects the final sum, they are challenged to find five different numbers that lead to a...
