Supreme Court Welcome
ORC# 7867
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: This two-lesson unit allows students to investigate the triangular numbers in an interesting, real-world context, the Supreme Court. Beginning with the classic handshake problem, students generate geometric and algebraic representations for the patterns they encounter and conclude with a formula for the nth triangular number....

Armstrong Numbers
ORC# 7396
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: An Armstrong number is an n-digit number that is equal to the sum of the nth powers of its digits. In this lesson, students will explore Armstrong numbers, identify all Armstrong numbers less than 1000, and investigate the recursive sequences that arise in some cases....

Rectangle Pattern Challenges
ORC# 621
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Students analyze three stages of a colorful rectangular pattern, and then determine the composition of future stages. Younger students can describe in words how the pattern grows, while older students can find algebraic expressions for the number of blocks of each color in the pattern....

More Complicated Functions: Introduction to Linear Functions
ORC# 5077
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: This lesson helps students who are not already familiar with the slope-intercept form of a linear function, y = mx + b, to analyze how the values of m and b correspond to changes in y as x systematically increases. This analysis helps students identify linear function rules involving two operations....

ORC# 4260
Resource Information
Resource Type: Lessons
Discipline: Mathematics
Professional Commentary: Students use strips of paper divided into three segments of various lengths to see which strips can form triangles. The goal is for students to discover the triangle inequality, namely, that the sum of the lengths of any two sides must exceed the length of the other side....
