New ReviewScholars warm-up their map skills with a discussion using location words to describe familiar places. An engaging video informs class members about latitude and longitude. Three leveled activities extend the learning experience for...

New ReviewLine, shape, color, texture, space. The first in a three-part series of lessons intended for advanced theatre arts classes introduces the elements of set design. Class members examine maquettes and analyze how designers have put together...

New ReviewBuild a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

Have everything you need to know about the elements of poetry with a nine-page handout. Split into four categories—word sounds, meanings, arrangement, and imagery—budding poets may reference terms, read definitions, descriptions, and...

Math can help make sound business decisions. A contextual-based instructional activity challenges young scholars to write and graph linear equations to model the cost of printing textbooks at different companies. They analyze the...

Discover the parallel structure of parallel lines. Provided with two parallel lines on a coordinate plane, the presenter shows that the rise and run, or slope, of the two lines are the same. The resource, which is a portion of a larger...

Perpendicular lines are all right. Using the definition of perpendicular, the video lesson introduces perpendicular lines.The portion a basic geometry playlist makes connections between the rules of parallel lines and perpendicular lines.

Build up the basics of geometry, one point at a time. The segment in an extensive playlist on basic geometry provides the definitions of the essential building blocks of geometry. Using drawings, the video shows examples and descriptions.

How can your class determine the relationship between experimental data? Learners discover how to express direct and inverse relationships through examples and sample problems in a video. The narrator takes data from tabular to graphical...

Search high and low for geometry. Using cameras, groups scour the school campus looking for geometric figures. The goal is to collect the most points by finding the higher scoring geometric figures for each category.

Navigate your way through a lesson on types of lines. Individuals drag line segments to illustrate paths between pairs of houses on an interactive map. They determine if these line segment pairs are intersecting or parallel.

If lines aren't parallel or perpendicular, then what are they? An interactive lets users rotate a line to change its orientation with respect to another line. It then indicates whether the lines are parallel, perpendicular, or...

Can you define that basic figure? Building upon the undefined terms in geometry, the instructional activity defines basic geometry figures. The resource defines line segment, ray, angle, perpendicular lines, and parallel lines.

Geometry begins with a point. The video introduces the concepts of points, lines, and planes. Using diagrams, the presenter includes how to name the objects along with how to write the names. Previewing the concept of 3-D space ends the...

Gain some perspective on linear pairs. Aspiring mathematicians adjust the vanishing point on a perspective drawing. They see the effect on linear pairs of angles and answer five challenge questions based on their observations.

Discover how circles help determine a perpendicular line. Using the applet, scholars construct the perpendicular to a line from a point. The interactive allows pupils to change the position of the line and perform each step of the...

Given a certain amount of points, how many line segments can you connect between them? How many close geometric figures can you create? These are the types of questions learners are asked to solve in a assessment-based worksheet.

The stars are aligned for a great interactive resource. The interactive contains a graphic of Ursa Major. Given a movable ray, pupils check to see if the three stars that make the handle are collinear. They investigate the constellation...

How do you calculate problems in alternate dimensions? The interactive allows learners to manipulate points in 2-D as scholars explore the relationship the points must have to create a one-dimensional object. Pupils identify objects that...

This resource on learning about slopes from A-frames is A-okay. A simple interactive has learners adjust the height and width of an A-frame house, and then calculate the slope of the roof for each situation.

Make points about the definition of a line segment. Scholars draw a line segment and indicate clearly what is the segment. The pupils determine a precise definition of a line segment using the concept of a point.

A dilation of two doubles the length of a line segment, but what about a line? Young mathematicians investigate how a dilation through a point not on a line affects a line.

Get the right definition of perpendicular lines. The short assessment asks pupils to draw a pair of perpendicular lines and label them. The scholars develop a definition of perpendicular lines that contains the right amount of...

Get a perspective of lines that share a point. The interactive displays a family of lines that share the same y-intercept. Individuals can find the equations of the lines by moving the line displayed and find what is common about all the...
