Use the handout as guided or independent practice in drawing a reflection of a rectangle over a line. Three rectangles are provided for practice in addition to a critical thinking question.

Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project...

Young scholars graph lines and identify the slope. In this algebra instructional activity, students graph a line using y=mx+b and graph lines that are horizontal or vertical. They calculate the slope of the line using two points, and...

Make these funky checker board patterns. They will not only add fun decoration to your classroom, but your pupils will be able to practice using simple geometry tools.They will use tools to make lines and circular shapes using a ruler,...

Students solve problems with slopes. In this algebra lesson, students identify the slope of a line and relate it to the rate of change.  They graph their lines on the TI and observe changes in the lines.

Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.

Students use corrugated cardboard to create a printed relief project. Using the cardboard, they review geometric designs, shapes and discover how to use vertical and horizontal lines. They practice relief printing with different materials.

Students create name art. In this visual arts lesson, students use horizontal, vertical, and diagonal lines to highlight their own names in print. Students use primary colors to create secondary colors in the project.

Students find and define the slope of a line. In this algebra lesson,students differentiate between positive and negative slopes. They define the properties and slopes of vertical and horizontal lines.

Learners observe and demonstrate a variety of basic geometric constructions using the Triman Safety Compass. Using the compass, they draw circles, bisect a line segment, construct an angle, bisect an angle, copy an angle, and create...

Students display knowledge of line of symmetry by designing a geometric stained glass window pattern.

Elementary schoolers make and use bar graphs to picture information. They learn how choosing the right scale for a bar graph can help make a persuasive argument. This is a terrific lesson on graphing which should excite your kids. There...

For use with a TI-nspire calculator, this instructional activity focuses on adding and subtracting polynomials. Learners use calculator to add and subtract polynomials using both the vertical method horizontal methods. A class discussion...

Define the terms domain, range, function, vertical limit test, and linear function notation with your class. They can then, graph several equations applying the vertical line test to determine which are and which are not functions, write...

Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs...

Teach how graphic designers can use mathematics to represent three-dimensional movement on a two-dimensional television surface. Pupils use matrices, vectors, and transformations to model rotational movement. Their exploration involves...

Young geometers explore relationships between units of measure and objects. Three activities provide varied opportunities to practice. Learners calculate the volume of two cylinders made by rolling a piece of paper vertically and...

Develop the rules for adding rational numbers. Pupils continue to work on adding integers. Young mathematicians use their experiences to develop the rules for adding integers with like and unlike signs. They finish the lesson plan by...

Fourth graders examine mirror symmetry. In this symmetry lesson, 4th graders discover that symmetry is not always vertical or horizontal. Students cut and fold shapes along lines of symmetry.

Students create a picture of an actual scene or overlap the called out lines or shapes into a space-breaker. If someone calls out a line or shape a student had not planned to use in the art, they have to figure out some way to use it...

Sixth graders, in groups, are given different parts of the whole project. They use information from Busch Gardens to explore line graphs, averages, and other math vocabulary.

Young scholars create a calligraphy piece using Korean words. They use han'gul script and write with a brush after learning the words. They pay attention to line and space as they create their work of art.

Eighth graders experiment with M&M's and a cup attached to a spring to to simulate a bungee jump. They graph the results of the experiment and make predictions for continuing the experiment. They determine the "line of best fit."

Students dentify patterns in their everyday environment. They create several types of pattern, including hatching, crosshatching, and stippling and discover that hatching lines may be drawn horizontally, vertically, or diagonally.
