Third graders use a number of problem solving strategies in this unit of lessons. They determine how to draw and model three-dimensional objects, use co-ordinate systems, determine probability of events, and identify paths of simple...

Pupils investigate the integrity and strength of different types of food wraps. They test the wraps and create a graphic organizer for the data. Once it is organized then a lab report can be written. The lesson contains background...

Students examine the use of signal flags on vessels. They use measurements and symmetry to create their very own signal flag. Students work together and as individuals to solve problems and express their ideas.

Tenth graders identify the trigonometric ratios for right angled triangles. Through independent investigation, they discover the constancy between the ratios of any two sides of similar triangles. In an alternative method, 10th graders...

Students define kinetic energy and know the effects of weight and speed on momentum.  In this investigative lesson plan students get into groups and design a roller coaster. 

Fifth graders practice using estimation. In this estimation lesson, 5th graders add, subtract, multiple, and divide using whole numbers, fractions, and decimals. Students decide upon instances when estimation is more appropriate than...

Students use Geometers SketchPad to find the area and perimeter of several shapes. For this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Review constructing angles with a protractor, then try constructing some of your own.

This short lesson focuses more on the angle bisector theorem. Learn about the angle bisector theorem proof, triangle angle bisector theorem, how to construct angle bisector, and other interesting properties and facts around angle bisectors.

A comprehensive guide for learning all about angles with definitions, examples, and practice questions.

Use Cabri Jr. and the Compass command to complete the actual construction - pencil, paper, and compass process.

Practice constructing angles given the degree measure.

Use a protractor to construct angles. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Three geometric constructions students like to say are "impossible" are explained here. Trisecting an angle, squaring a circle, and doubling a cube are examined as being either possible or impossible, depending on the "rules" you use.

In this interactive website, students practice various math skills such as identifying different types of angles, use the degree symbol, estimate and measure angles, and construct angles.

This site from Advogato is all about angles. It contains information starting with what an angle is and what it looks like, all the way up to bisecting angles and theorems about angles. This is very good information for students just...

Learn all about the basic geometric constructions in this test prep lesson. You will explore line segments and points, and understand key terms like the terms parallel and perpendicular. Construction activities and interactive online...

Learn about drawing shapes using only a compass and straight edge or ruler with out measuring any lengths or angles.

In this exercise, students practice drawing angles. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Practice constructing triangles. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this activity, students will construct angle bisectors and medians in quadrilaterals and explore the properties that appear to be true for four-sided figures. They may find it necessary to review the definitions and properties of...

Construct a copy of a line segment in this interactive exercise.

This task provides a construction of the angle bisector of an angle by reducing it to the bisection of an angle to finding the midpoint of a line segment. Aligns with G-CO.D.12.

This site provides a step-by-step method to construct congruent segments and angles with a straight edge and compass.
