Students investigate triangles and their properties. In this geometry lesson, students differentiate between similar and congruent triangles. They use the SSS theorem to help identify the triangles that are similar or congruent.

Double win with a comprehensive worksheet and an excellent worked out answer key. The worksheet itself is twelve pages and begins with the simple sine and cosine graphs, then, develops into the reciprocal trig functions. 

Students work together to grid a 2 x 2 meter unit using the formula for the Pythagorean Theorem. After creating the grid, they identify the location of artifacts and create a map of their location. They develop a graph and table of their...

Pupils examine how archaeologists establish and maintain the context of artifacts. They interpret a plan view of an archaeological site and explain the importance of the grid system.

Learners play a grid-based game and devise clues to help classmates locate spots on the globe in order to recognize the value of using longitude and latitude for identifying locations.

High schoolers graph polar graphs. In this calculus lesson, students convert between polar and rectangular coordinates. They graph their solution on the TI calculator and make observations.

Students are asked to describe to a partner how he or she walks to school or the bus stop. They are shown on the overhead an one-inch grid paper, and at the intersection of two lines on the grid paper, students are shown a house and...

Young scholars are introduced to the concepts of latitude and longitude. In groups, they identify the Earth's magnetic field and the disadvantages of using compasses for navigation. They identify the major lines of latitude and longitude...

Students use a world outline map to locate places using coordinates of latitude and longitude. They answer questions about places based on their knowledge of the map and on their research and make up more questions of this sort for each...

Students are introduced to connecting graphing in a coordinate plane to making scatterplots on a graphing calculator. Working in pairs, they connect points plotted to make a sailboat and complete questions on a worksheet as well as plot...

Students work in pairs to measure their arm span and height and record them on a class chart. The class works together to create a scattergram to display the data. Class discussion focuses on interpreting the scattergram.

Students study the components of a bedrock geology map through a hands-on activity involving a cookie and graph paper.

Students investigate polygons and their lattice. In this calculus lesson plan, students record data using different methods. They analyze their data and draw conclusions based on the relationship between the area and the interior lattice.

In this calculator active graphing worksheet, students graph 12 equations via a calculator and transfer the graphs onto coordinate grids.

In this math learning exercise, students practice their skills in constructing reflections of shapes that are on a grid. This learning exercise has 13 problems for the students to solve, and includes an answer sheet.

Fifth graders examine the geometry of quilts. They discuss the history of quilting, design two nine-patch squares, exchange one design on an Internet bulletin board, and construct a hot pad that is quilted.

A function is like a machine that has an input and an output. Challenge scholars to look at the eight given points and determine the two functions that would fit four of the points each — one is linear and the other non-linear. The...

Discover how to solve systems of inequalities by graphing. An informative video shows pupils how to determine the solution set after graphing each inequality of a system. To finish, a worksheet gives them a chance to practice this skill.

Once you know how to graph y = b^x, the sky's the limit. Young mathematicians learn to graph basic exponential functions and identify key features, and then graph functions of the form f(x) = ab^(x – h) + k from the function f(x) = b^x.

Combine linear equations and a little creativity to produce a work of art. Math scholars create a design as they graph a list of linear equations. Their project results in a stained glass window pattern that they color.

Fit functions to data by using an interactive app. Individuals plot a scatter plot and then fit lines of best fit and regression curves to the data. The use of an app gives learners the opportunity to try out different functions to see...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Avoid the mines and win the game! Young scholars direct a robot through a minefield by plotting points. Their goal is to reach the target in as few moves as possible.

Connect graphs, equations, and tables for real-world problems. Young mathematicians analyze relationships to identify independent and dependent variables. These identifications help create tables and graphs for each situation.
