As a short review of punctuation, such as the use of commas and semicolons, this presentation could be helpful in an upper elementary classroom. The series of slides defines each term and provides examples.

Budding artists or mathematicians read about,and then draw, two very different shapes. Geometric and organic 2-D shapes are defined. Learners use the definitions to draw examples of each.

After your class finishes reading Bud, Not Buddy by Christopher Paul Curtis, they use the Venn diagram here to compare two characters from the novel, in this case Bud and his grandfather Herman E. Calloway. Examples of qualities on which...

Start this activity with a brief description of how to solve absolute value inequalities. A space is provided to help classify the inequalities into types (greater than, less than, or equal to) and for learners to show how to graph their...

Use this worksheet as a warm up, a refresher exercise, or a practice after a more detailed lesson on graphing linear inequalities in two variables. Start with boundaries that are horizontal or vertical, then move into graphs with...

This lesson focuses on unit conversion, proportions, ratios, exponents, and the metric system. Discuss measurement with your math class and demonstrate how to solve several health-science word problems. Give learners a chance to visit an...

Is consistency foolish? Or is “foolish consistency . . . the hobgoblin of little minds”? Ralph Waldo Emerson’s “Self Reliance” provides readers with an opportunity to reflect on their own musing about being self-reliant and about...

Learners see application of construction techniques in a short but sophisticated problem. Combining the properties of inscribed triangles with tangent lines and radii makes a nice bridge between units, a way of using...

Horses need exercise, too. Scholars create linear equations to model the perimeter of exercise fields for horses. They finish by solving their equations for the length and width of the fields.

Find the age of a fictional sample of rocks using a genuine approach. A well-designed lesson asks young mathematicians to use exponential modeling to analyze half-life. As a project-based learning activity, scholars communicate...

Students identify chords and angles. In this geometry lesson, students calculate the length of the chords inside and outside of-the circle. They differentiate between tangent and secant lines.

Teach your math lovers how to solve linear equations by graphing. Learners identify pairs of coordinates and use it to graph a line and use the TI to graph and observe the line.

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

In this triangles worksheet, 10th graders solve 3 extensive informal geometry problems that involve triangles. First, they sketch a triangle, selecting 3 of the sides and constructing 3 midpoints. Students then draw each of 3 medians by...

In this tangents, secants and chords worksheet, 10th graders identify and solve 48 different problems that include using 3 different theorems for defining circles. First, they determine the area of each circle with C as the center and a...

In this stars rise in the east worksheet, students use geometry to show how the Earth rotates from west to east and why celestial bodies appear to rise in the east and set in the west. Students draw a figure and label given points in...

In this probability worksheet, 11th graders analyze how many students participate in four different sports using the probability of an event ocurring. There are 4 questions on this worksheet.

Tenth graders investigate parallel lines and their special angles cut by a transversal. In this geometry lesson, 10th graders identify and find corresponding, alternate interior, and alternate exterior angles formed when parallel lines...

In this algebra worksheet, students evaluate exponential functions using tables and graphs. There are 6 questions with an answer key.

Students examine abiotic and biotic factors. They define biotic and abiotic, categorize a list of items onto a Venn diagram, label various items from areas on the school grounds as biotic or abiotic, and diagram a magazine picture.

Students examine how a pebble calculator works and compare it to an abacus. After a discussion on the abacus and pebble calculator and how each works, they construct their own pebble calculators. They determine how to represent...

Learn how to evaluate the derivatives of polynomials.  Mathematicians find the derivative of a quadratic function and determine the value at a given value.  Learners compare the slope of the secant line through two points with...

Students imagine the way lines look. In this vector lesson, students recognize how to find a vector equation, Cartesian equation or perpendicular distance. Students find angles between planes. Students complete an activity with...

In this algebra worksheet, students solve systems of inequality using the graphing method. There are 5 questions with lots of examples and an answer key.
