Volume of Composite Shapes
It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of...
Curated OER
Triangle Sums
Fourth graders determine a way to place numbers in the nine circles that are arranged in a triangular pattern so that each side has an equal sum. They use each number once and practice adding single digit numbers.

Linear Systems: Diagonalizing a Matrix
In this diagonalizing a matrix worksheet, students explore matrix factorization and use diagonal decomposition. This two-page worksheet contains examples, explanations and four practice problems.
Curated OER
Investigation-Pattern/Functions
Students explore number patterns. In this number patterns and probability math lesson, students work in groups to describe the patterns present in the first five rows of Pascal's Triangle, then write numbers to continue this pattern....
Curated OER
Investigation - Patterns/Functions
Students will display the first five rows of Pascal's Triangle and discuss in their groups what patterns they see in the rows of numbers. They will give responses and discuss that these numbers form what is called Pascal's Triangle.

social studies: Life in Colonial America
Students explore the trials and tribulations early colonial life and note its successes. Through literature, Internet research, and interactive software, they engage in various activities to evaluate early social and cultural development.
Curated OER
Can Stack
Young scholars are able to find the rule for summing consecutive numbers;
identify the pattern of triangular numbers. They then solve the given problem using logic and mathematical reasoning.
Curated OER
Shaking Hands
Students use diagrams or lists to show relationships. They also identify the pattern of triangular numbers. The mathematics behind situations provide a way of problem solving to examine the answers.

The Rutherford Atomic Model: Hidden Obstacles
Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...
Curated OER
Tiling the Plane
Students use pattern blocks and triangular grid paper to review shape names, be introduced to the concept of a tiling of the plane, and determine which pattern blocks tile the plane. They are asked: "Have you ever seen a floor or a wall...
Curated OER
Rows of Numbers
Students generate patterns from a structured situation, find a rule for the general term, and express it in words and symbols. They also devise and use problem solving strategies in a systematic way.
