Compare graphing an inequality in one variable on a number line to graphing an inequality in two variables on a coordinate plane. Young mathematicians work on a puzzle matching inequalities and their solutions. They then complete a...

Just how far away from the mean is the data point? Pupils calculate the standard deviation for a set of data and find out how many standard deviations a point is away from the mean. The teacher leads a discussion on how to calculate...

Sixth graders investigate the concept of prime and composite numbers. They use a review of multiplication to help explain factoring. Students are taught the definition of a prime and composite number and then practice independently.

In this addition facts review worksheet, learners fill in the 60 blanks in an addition chart. Completion of the chart requires students to add using the numbers 1-10.

In this multiplication facts review learning exercise, students fill in the 20 blanks in a multiplication chart. Completion of the chart requires students to multiply using the numbers 1-10.

In this multiplication facts review instructional activity, students fill in the 50 blanks in a multiplication chart. Completion of the chart requires students to multiply using the numbers 1-10.

In this multiplication facts review learning exercise, students fill in the 80 blanks in a multiplication chart. Completion of the chart requires students to multiply using the numbers 1-10.

Students participate in a game with different types of polygons. They use triangles to create as many polygons as possible. They also review their colors by having different polygons be a different color.

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Investigate vectors in standard positions and use the CellSheet application on the TI calculator to find the sum of two vectors. Convert from polar to rectangular coordinates and vice versa, and show graphs of the vectors.

Explore linear functions! In this Algebra I lesson, mathematicians graph data in a scatter plot and use a graphing calculator to find a linear regression and/or a median-median line. They use the model to make predictions.

In this geometry worksheet, 10th graders examine and evaluate their understanding of many of the basic concepts of geometry. The six page worksheet contains thirty-five questions. Answers are not provided. 

Introduce the inverse matrix method to solve systems of linear equations both algebraically and graphically. Using given data, your class checks their answers with graphing calculators. Handouts are included in this well-thought out lesson.

Apply systems of inequalities to a real-world problem. Here, scholars learn to graph solutions to systems of linear inequalities. To finish the lesson, they solve a problem involving burgers and cheeseburgers using a system of inequalities.

Connect functions to geometry. In the ninth installment of a 12-part module, young mathematicians create functions by investigating situations in geometry. They look at both area and volume of figures to complete a well-rounded lesson.

High schoolers analyze the vertex form of a parabola and find an approximate fit of a model. They explain the quadratic parabola function and its properties by developing quadratic models. They use translation and dilation to change the...

Mathematicians explore cubic functions by learning how to investigate the relationship between the x-coordinates of the three zeros of a cubic function.  The lesson also contains an application of differentiation. 

Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

Why do shadows look different in the summer than in the winter? What causes day and night? How can a sundial be used to tell time? Answer these questions and more through two engaging lessons about light and shadows. Fourth and fifth...

Introduce pupils to the two types of reasoning, inductive and deductive. Classmates work in pairs or small groups to learn the difference between the two and apply these reasonings to develop valid conclusions. 

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

Youngsters search for an animal with body parts for each number from one to ten during a field trip to an aquarium. They count rays, fins, feet, gills, eyes, spots or anything. When they get back to the classroom, they compile their...

Become familiar with adding integers by practicing examples using negative and positive numbers. Students discuss how they arrived at their answers.
