Exploring Geometry in the Real World
Students find real-world examples of a variety of geometric shapes. They conduct research, record observations, and write descriptions. They create a classroom cityscape and highlight the information they gathered. They present an oral...
Curated OER
Perpendicular Segments in a Circle
High schoolers explore the concept of circles as they construct a circle using a program such as Cabri Jr. Learners construct a chord and a diameter that are perpendicular, then measure the bisected chord and notice that both sides of...
Curated OER
Investigating Segments in a Right Triangle
High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...
Curated OER
Triangle Sum Theorem
Teach your class how to solve problems using the triangle sum theorem. For this geometry lesson, high schoolers identify the missing angles in a triangle using the sum theorem. They graph triangles on the TI and moves the sides around to...
Curated OER
Measuring Angles in a Triangle
High schoolers investigate the sum of the measures of the angles of a triangle. They draw a triangle and measure the interior angles. Using Cabri Jr., learners find the sum of the measures of the interior angles. The lesson provides an...
Curated OER
Reflections in the Plane
Have your class explore the concept of reflections as they use Cabri Jr. to construct a triangle and reflect it over a line. Learners reflect shapes across the coordinate plane and across the lines y = x and y = -x.
Curated OER
Congruent Trianges - Is This Enough Information?
Seventh graders determine whether two triangles are congruent and provide an explanation to why they are not. They apply concepts of measurement of angles and collect evidence of congruent angles in the world.
Curated OER
Modeling Addition: Commutative Property and Zero Property
First graders practice modeling addition. In this hands-on addition lesson plan, 1st graders are introduced to the Commutative Property of Addition and the Zero Property of Addition through modeling and the use of manipulatives. This...
Curated OER
Transitive Property of Inequality
In this transitive property worksheet, students use the transitive property to help them solve the riddle for the order of men and where they stand. Students solve the riddle for 10 men.
Curated OER
Associative and Commutative Properties
Seventh graders define the commutative and associate properties and extend commutativity and associativity to objects. They define rational numbers and review the order of operations and multiplying/dividing integers chart. In addition,...
Curated OER
Area-Time to Get in Shape
Students investigate the properties of triangles and parallelograms. In this geometry lesson, students calculate the formula used to find the are of a triangle and other polygons. They create a visual model to represent their findings.
Curated OER
Similar Triangles on the Coordinate Plane
Young scholars investigate triangles and their properties. In this geometry lesson, students differentiate between similar and congruent triangles. They use the SSS theorem to help identify the triangles that are similar or congruent.
