Graph and solve linear equations in two variables. The class relates the concepts of linear equations to the real world.

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

Here is an engaging lesson on solving equations with two variables. Have the class rewrite linear equations in the slope intercept form, y=mx + b. They graph the lines using the slope and y-intercepts.

Students solve equations by writing expressions. In this algebra lesson, students identify the different values for each variable. They use the navigator to see how to solve equations.

Students experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.

Students experiment with point graphs. In this math instructional activity, students are divided into groups and perform an experiment to see how high a ball bounces, recording their results on a point graph. Students then answer...

High schoolers investigate perimeter patterns formed by a hexagon and a triangle. They will identify the dependent and independent variable and write a function for the relationship.

Experimentally, come up with a study design. Learners hear about different types of study designs, observational studies, and experiments. They identify the subjects, response variable, treatment, and whether there was a cause and...

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

Learners experiment with graphing. In this graphing introduction lesson, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another estimation example with...

High schoolers explore algebraic expressions in this Algebra I lesson. They evaluate expressions using paper and pencil and then use the TI-83 to provide immediate reinforcements.

Change one variable and try again. Teams build basic balsa gliders and collect data on their flight distances and times. Through collaboration, the team decides on two modifications to make to the basic design and collect data for the...

Use a hands-on approach to exploring the concepts of related rates in your AP Calculus class. Individuals explore the effect of the rate of change on a variable related to a variable they control. After analyzing the data they...

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...

Students investigate what a controlled group is by creating an experiment.  In this plant growth lesson, students identify the different parts of a plant and discuss what is needed for a plant to be successfully grown....

Students conduct an experiment to determine which style of tape will stick the best.  In this controlled experiment lesson, students predict which tape will stick best to a marble that rolls over it, then they conduct the experiment...

Sixth graders set up a pendulum experiment deciding which variable to manipulate (length of string or weight on the string). They create a hypothesis, collect necessary equipment, and write out each step of their experiment. They then...

High schoolers determine the volume of a rectangular prism. They then maximize and minimize the volume given variable side lengths.  Finally, they factor the volume equation to determine the side lengths.

Pupils analyze the variables in the formula of a compound interest. They model the increase or decrease of an investment using compound interest and discuss different compounding periods.

Students engage in a instructional activity that gives them the tools needed to become knowledgeable credit consumers. The companion website for the ITV program TV-411 is used to provide learners with an interactive experience of what...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Students explore linear relationships. In this sixth through eighth grade mathematics lesson, students explore the symbolic representation of verbal descriptions of mathematical rules defining the relationship between two variables.

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson, the resource guides kids through starting their class garden as they...
