Pupils solve problems using fractals. In this geometry lesson, students identify properties of fractals. They find patterns in their surroundings and relate it to the real world and math.

Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...

Students construct perpendicular lines. In this geometry lesson, students use a compass and straight edge to do construction. They start from a point to a line.

Students identify properties of trapezoids. In this geometry lesson, students are put into groups and use computer programs to analyze polygons. They drag and move the shapes around as they make predictions.

Ninth graders design a safe passage through a 2-D obstacle. In this geometric math instructional activity, 9th graders engage in a hands on activity to better understand the concept of geometric and algebraic perpendicularity. Students...

Students construct midsegments. In this geometry lesson, students make conjectures and apply properties of triangles to solve problems. They complete an activity on the computer.

Ninth graders investigate the segment addition postulate.  In this geometry lesson, 9th graders explore the difference between equal and congruent in relation to segment length.  The lesson includes an algebra application and a...

In this printing activity, learners form the upper and lowercase letter U. Students also color in two pictures that begin with the letter U.

Students identify the relationship between chords, secants and circles. In this geometry lesson, students calculate the length of the chords. They sketch the secant lines on a circle.

First graders create Aboriginal Dot Turtles using wax colors or crayons. The class discusses Aboriginal stories and art as a way to practice design. This lesson can be done in two 30-minute lesson segments.

Learners find locations based upon their latitude and longitude coordinates. In this latitude and longitude lesson, students locate points on a grid and learn how to use an astrolabe.

Students apply a four step critique process as they observe and make personal decisions about abstract artworks.

Students identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

In this similar triangles worksheet, 10th graders solve and complete 10 different problems related to determining the sides of similar triangles. First, they write three equal ratios to show the corresponding sides that are proportional....

In this geometry activity, students use a ruler and a protractor to measure the lengths of the line segments and size of the angles that make up a drawing of a Christmas tree.  The one page activity has one problem.  Answers...

For this printing activity, learners form the upper and lowercase letter Ii. Students also color in pictures that begin with the letter Ii.
