Curated OER
Integrating Functions
For this math worksheet, students find the answers to the functions that includes integration and trigonometry. They use the examples for help with the special functions.
Curated OER
Solve-Real roots-Intersections
In this math worksheet students complete a series of multiple choice questions including calculating intersections using x and y axis.
Curated OER
Coordinate Geometry
In this geometry learning exercise, students calculate the midpoint and distance between two points. They use the correct formula to solve the area and perimeter of polygons. There are 20 multiple choice questions with an answer key.

Extending Pattern Understandings
Students use shapes and manipulatives to demonstrate patterns. For this patterns lesson plan, students also break up patterns to identify a pattern unit.
Curated OER
Vertical and Horizontal Translations
Eleventh graders study seven functions. They use their handheld calculator to determine which family of functions the equation belongs, the parent function described, and they calculate the vertical and horizontal translation.
Curated OER
Survivor
Seventh graders investigate changes in the ecosystem within the school year. They see that ecosystems, communities, populations, and organisms are dynamic and change over time. They, in groups, collect data in quadrants in the fall,...
Curated OER
Exploring Centers of Triangles
Students explore properties of triangles using angle bisectors, incenters, circles, midpoints, and altitudes. They use Geometer's Sketchpad in order to create triangles and their properties.
Curated OER
The Truth About Triangles and Squares
Fourth graders investigate the patterns associated with both triangular and square numbers. They use counters as manipulatives to depict the numbers as needed but focus on problem solving using mental math techniques.
Curated OER
Can Stack
Students 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
Square Milk Bottle Crates
Students attempt a problem that Students has the potential to have more than one solution. Hence the problem is accessible to a wide range of students. The problem is essentially about finding patterns and this is typical of a number of...
Curated OER
Looking For Triangles
Students solve problems with triangles. In this geometry lesson, students analyze shapes to find different triangles. They name the shapes created by putting triangles together.
Curated OER
Properties of Logarithms
Eleventh graders investigate logarithms. In this Algebra II lesson plan, 11th graders explore the properties of logarithms that are used to simplify expression and solve equations. Students confirm their conjectures regarding the...
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.
Curated OER
Poppy Meets Pythagoras
Eighth graders find connections between numbers in a table; use Pythagoras' theorem in a general algebraic form; and measure accurately from a scale drawing to find a method that might enable the helicopter to land inside a rectangular...
Curated OER
Wind, Pressure, Force, Calculus and Engineering Connections
Twelfth graders solve first order differential equations using the separation of variables technique. In this calculus lesson, 12th graders explain the connection between math and engineering. They brainstorm what engineers do in real life.
