By learning to select the best representation for three meal plans, students compare three meal plans to determine the best choice. Data for the meal plans is sorted on a table, as an algebraic equation, and graphed on a coordinate grid....

Learners solve problems using trigonometric functions, specifically a problem about a tree stand. Pupils try to maximize the distance of hunting sight given certain restrictions. They use the Pythagorean Theorem, sine, cosine, and...

Fifth graders use the Internet to learn about translations, reflections and rotations. Students access the Transmographer program on the Internet, where they practice what they have learned. Students also complete a worksheet.

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 define accuracy and precision, and differentiate between the two terms, apply the concepts of accuracy and precision to a given situation and correctly apply the concept of significant figures to measurement and mathematical...

Students calculate the slope of a line. In this slope lesson, students use a graph, an equation or two points to help them calculate the slope of a line. They differentiate between a slope of zero and an undefined slope.

Young scholars investigate functions and their transformations. They move absolute value functions around on the coordinate plane, and then define the transformation and plot the new graph. The table feature of the TI-calculator is used...

Mathematicians graph logarithmic equations. Teach your young scholars how to identify the intercepts of logarithmic equations and tell whether the function is increasing or decreasing. They find the domain and range of each function.

Students explore number sense by solving consumer math problems. For this pattern identification lesson, students analyze a list of numerical and geometric patterns while predicting the future outcome. Students utilize inference skills...

Students explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson which provides great demonstrations and hands-on activities.

Students investigate the engineering design process and the relationship between distance, time, and speed. Using a generic car base, small groups design a device that will protect an egg on or in the car as it is rolled down a ramp at...

Students compare and contrast the various types of rocks on each continent. In groups, the calculate the rock ages and types to determine if the continents, in their opinion, were joined at one time. They develop two imaginary...

Third graders discover a connection between numbers of things in groups and groups. They solve number line puzzles for multiplications and identify data for 3 riddles in a multiplication context. They use number lines as sources for...

Fourth graders use pattern blocks to explore areas of polygons. They explain that the answers to the area of the same polygon vary according to the units of measurement used. They visualize how different units of measurement can be used...

Students apply definitions and theorems to verify special quadrilaterals using coordinate geometry. They apply the slope formula, the midpoint formula, and the distance formula to justify that a given quadrilateral is a parallelogram....

Students find the coordinates of the vertices of special quadrilaterals placed in the coordinate plane. They find the coordinates of missing vertices of squares and parallelograms.

Students explore the concept data sets.  In this data sets lesson, students find the 5 number summaries for salaries of teachers and compare them with 5 number summaries of professional baseball players.  Students use box and...

Students investigate proofs used to solve geometric problems. In this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable to...

Geometry adventurers study circumference of a circle as they listen to Sir Circumference and the Dragon Pi, by Cindy Neuschwander. In groups, they use string to measure the diameter and circumference of circular objects and...

Students view groups of pickles and discuss putting the groups together. Next, they discuss a group of pickles and cucumbers, can these be put together? Students listen as the teacher explains equivalent fractions and ways to change...

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.

Students use graphing calculators to graph lines and create tables of values. They perform an experiment using M&M's and slinkys, then create their tables based on their results.

Students measure distances and report them in fractions. They convert fractions to decimals and multiply decimals.

Students solve right triangles using the Pythagorean Theorem.  In this solving right triangles using the Pythagorean Theorem lesson, students find the missing side of a right triangle.  Students find the hypotenuse given two...
