Similar triangles
Tenth graders investigate the theorems of ASA, AAS, AAA and ASA. In this geometry lesson, 10th graders discuss the theorems of triangles and how it is used to solve for missing sides or angles. They review how two angles are formed by...
Curated OER
Linear Equations and Angles
In this geometry worksheet, students identify the length of the different sides using equations. They solve for the unknown to identify similarity and congruence in angles and sides. There are 22 questions.
Curated OER
Angles and Transversals
Pupils explore the concept of angles and transversals. They construct parallel and non-parallel lines cut by a transversal using Cabri Jr. Learners then determine which angles are congruent and the relationship of angles when two lines...

Symmetry and Tangrams
Sixth graders build figures out of tangrams. In this symmetry lesson, 6th graders view tangrams and identify the polygons included in them. Students divide into groups, identify their tangram pieces, define the lines of symmetry, and use...

IGD: Perpendicular Bisector
Students draw perpendicular bisectors. In this perpendicular bisectors lesson, students identify the perpendicular bisector in a polygon. They use web tools to create and measure perpendicular bisectors. Students...
Curated OER
Slope Right Up
Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

What are Fractals?
Middle and high schoolers identify and analyze fractals and research information using the Internet to locate information about them. They look at fractals in relation to nature and other real world situations. Pupils create several...
Curated OER
Recognizing Patterns
Middle schoolers explore the concept of patterns. In this patterns lesson, students use applets to manipulate tessellations. Middle schoolers predict the next number in a sequence by recognizing patterns.

Silly Symmetrical Names
Fourth graders participate in hands-on activities to introduce them to the concept of symmetry. They make a silly symmetrical picture out of their names after gluing them onto a larger sheet of construction paper. This is a really...
Curated OER
Fractals
Students explore the concept of fractals. In this fractal lesson plan, students use applets to explore Koch's Snowflake, Sierpinski's Triangle, and other fractals. Students develop these concepts through exploration and teacher guided...

Ant Farm Fun
Third graders investigate ants and anthills in this series of lessons. They create their own Ant Farm.
Curated OER
Tricky Traps
Students create identify properties of trapezoids. In this geometry lesson, students calculate the area of given trapezoids and review the area formula for parallelograms. They draw a correlation between the area of a trapezoid and that...
