Students perform order of operation using integers. In this algebra lesson, students apply properties of integers as they add, subtract, multiply and divide integers. They work in groups to complete a RAFT assignment.

Students investigate simple linear functions by trying to guess a function rule from inputs and outputs. They write the function rule in algebraic form.

Learners analyze function graphs.  In this Algebra II/Pre-calculus activity, students investigate the graph of a function as they determine to which family of functions it belongs, determine the parent function and describe the...

Students develop a process for analyzing collected bayou data. They find the mathematical relationships among various biological factors. Students, work collaboratively using technology in their data analysis.

There are many different options for graphing data, which can be overwhelming even for experienced mathematcians. This time, the focus is on histograms and Venn diagrams that highlight the frequency of a range of data and overlap of...

Students investigate the volume of cones. In this geometry lesson, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Young scholars 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.

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...

Pupils will explore numbers rules. They will create a picture of their rule and exchange their paper with a classmate. The classmate works to figure out the rule. They then share with each other how they found the rule. Questions are...

Consider complex numbers, roots, and quadratic equations. Use the discriminate as a way to determine the nature of a quadratic's roots. Then discuss the similarities and differences between quadratics with two, one, or no real roots....

Students draw cross sections of given contour maps. In this math instructional activity, students interpret the different symbols used in the map. They determine slope and steepness through direct measurement.

Ninth graders participate in a lesson focused on the concept of basic statistics. They find the mean, median, and mode of different data sets. More advanced students could practice creating a bell curve from the data.

Seventh graders investigate the mathematical concept using a lecture format. The instructional activity includes a classroom management section with suggestions for instructional activity execution. Students write a definition for the...

Students engage in a lesson that is concerned with the rules of exponents. They practice solving problems that use exponents in a variety of contexts. Students are shown how to use the rules in numerical sequences and after translation...

Students investigate the concept of multiplying fractions and use the inverse for doing division. They practice working the problems with scaffolding provided by examples with the teacher. The link is made to real life with the...

Students review the Cartesian plane and the process of plotting points. In groups, students create tables, identify the slope and y-intercept, and graph the equation. Afterward, students perform the same process, only, individually. As a...

Students graph linear equations on a Cartesian plane. After describing data tables and their use, students explore how the information from a table can be used to create a line graph. They discuss reasons for plotting a minimum of...

Students explore the concept of logarithms.  In this logarithms lesson, students discuss the logarithm properties.  Students use linear functions as a basis to develop the logarithm properites by substituting log b and log a...

Students review how to solve and graph an inequality. They also review how to find simple interest from a given problem set. The teacher performs informal assessment through observation of students.

Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.

Eighth graders practice using the LIST key on graphing calculators using the proper syntax. They work with the functions of mean, median, and mode in a teacher led lesson and then with a partner on a second data set. They follow...

Young scholars become "shape detectives" as they identify, name, create and describe common shapes within pictures and objects found within the learning environment. Suggestions include incorporating shapes into all learning areas and...

First graders investigate the Commutative Property of Addition. It is introduced using models such as students, counters, balances and dominoes. They discover the order of the numbers in an addition sentence does not change the result...
