Upper elementary schoolers investigate the concept of multiplying fractions with the help of a handout and a treat of brownies. They work on a worksheet for a short while and then progress to multiplying a chain of terms. Then the...

Aspiring astronauts graph, interpret, and analyze data. They investigate the relationship between two variables in a problem situation. Using both graphic and symbolic representations they will grasp the concept of line of best fit to...

Students use calculator and non-calculator methods for analyzing data. They apply data collection and analysis in a study of mass and weight. Students enhance and apply the concept of line of best fit. They master graphing in a plane,...

Students explain why a transiting planet causes a periodic dimming in the light from its parent star. They determine the radius of a planet, and its orbital distance, by analyzing data and manipulating equations. Students compare the...

Students study a variety of math concepts in the context of cooking up a meal. In this math lesson, students calculate surface area and volume. They draw and interpret different types of graphs.

Students recognize, describe and extend patterns in three activities. They organize data, find patterns and describe the rule for the pattern as well as use the graphing calculator to graph the data to make and test predictions. In the...

Eighth graders identify and compare acute, right, obtuse, and straight angles. They draw two angles on pieces of construction paper so they can accurately know what it looks like. Students hang the drawings on the wall. They are asked...

Seventh graders play "What's my Rule" beginning with simple equations and working towards harder problems as student's gain confidence. They evaluate the equations by graphing them. Students identify the slope and y intercepts of the...

Students practice graphing compound inequalities. They draw a Venn Diagram on two different sports visualizing that their is a middle section on commonality among the two sports groups and then relate that concept to compound inequalities.

Eighth graders, after brainstorming all the places they see percentages in every day life (sales, basketball, grades, etc.), calculate percentages from bases and parts in word problems. They review their notes together on percentage...

Students use quilt patterns to illustrate ratios. In this fractions lesson, students color quilt patterns using given fractions and ratios of colors. A finished "quilt" is assembled from the work of the students. This is an...

Students analyze, create, and record repeating patterns. In this geometry lesson, students create shapes using patterns and keep track of the different shapes. They incorporate transformation and reflections into their patterns.

Students define and differentiate between experimental and theoretical probability. In this statistic lesson, students play the game "Monty Hall" and use probability to come up with the best strategies to play the game.

Students calculate ratio and proportion. In this unit rates lesson, students estimate using proportions and find their errors in doing so. They calculate unit rates and define the concept of unit rates.

This helpful lesson explores the probability in tossing a coin and throwing dice. Specifically, it looks at the probability of getting numbers that are significant to the game of craps, assuming that once the math is understood, most...

Students use hands-on activities to explore transformations. They view a video segment that demonstrate how M. C. Escher employed geometry and transformations to create so many of his famous drawings.

Young elementary students will discover there are patterns all around them in their daily lives. In groups, they sort pattern blocks by size and color. Using the internet, they create their own type of patterns and share them with the...

Analyze data using technology. Middle schoolers design data investigations, describe data, and draw their own conclusions. Then they select the best type of graph, graph and interpret the data, and look for patterns in trends. They also...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

Put out by Texas Instruments, this instructional activity involves learners in an activity focused on adding polynomials, solving equations, factoring trinomials, and expanding binomials. A TI-89 calculator is needed to complete this...

To find x, you have to get it by itself, correct? Individuals solve a linear word problem and share their solutions with others that solved the problem in a similar fashion. They then complete a self-assessment on how they feel about...

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson plan in a seven-part series challenges scholars to find the mass and volume of two unknown liquids....

Put geometry skills to the test! Learners solve compound inequalities and then graph the inequalities on a coordinate plane using their geometric skills. They identify the slope and y-intercept in order to graph correctly. I like this...

Use tables, graphs, and substitution to solve systems of linear equations. An envelope of sample problems is passed around the classroom, and each learner has the opportunity to solve the system in the envelope. This is a great way to...
