Students examine how driving a hybrid car can save money and cut down on pollution.  In this hybrid vehicles lesson plan students complete an exercise that shows them how to work with proportions, percents, dimensional analysis and...

Students convert recipes for tortillas. They calculate the amounts of ingredients as they convert recipes and write an explanation of the task to demonstrate their calculations. After reviewing their calculations, they demonstrate how...

Students use concrete and pictorial representation of geometric patterns to extend patterns. In this geometric patterns lesson plan, students identify patterns and extend them.

Students examine the concept of sequences. Students create a sequence using varied starting numbers, multipliers, and add on values. Students practice determining the starting values to use in order to produce a desired sequence.

Young scholars discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and...

Students work together to discover the flow rates of faucets and rivers. They relate their results to engineering and applied science concepts. They make predictions on the flow rate of a nearby river in their local community.

The middle schoolers will extend the knowledge of algebraic expressions from geometric representations and ultimately graph linear equations with understanding. The students will also develop a better understanding of algebraic...

This lesson introduces students to Activity Center. The following lesson represents a suggested TI-Navigator classroom procedure for students to explore solving linear equations algebraically, numerically, and graphically.

The lesson investigates how to graph linear equations. The tutorial includes definitions, examples, and a worksheet.

Gain an understanding of linear equations in the coordinate plane by viewing examples and a video lesson. [2:56]

In this exercise, students practice solving linear equations with variables on both sides (decimals and fractions). Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

In this exercise, students practice graphing solutions to two-variable linear equations. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Solve a number riddle by finding the point of intersection for two lines. This video focuses on finding the solution for a system of equations, they are represented as an algebraic expression and a set of linear equations that are...

A quick, four-part review of graphing lines.

n this task students use different representations to analyze the relationship between two quantities and to solve a real world problem. The situation presented provides a good opportunity to make connections between the information...

Discover the importance of finding the equations of lines.

Demonstrates, step-by-step and with illustrations, how to use slope and the y-intercept to graph straight lines.

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.

In this exercise, students practice graphing from a standard form equation. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

A short tutorial explaining the linear equations of horizontal and vertical lines.

This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...
