Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, students use the TI to create a visual of their shape.

Students find the diagonals of the quadrilaterals. In this geometry lesson plan, students identify and use properties of quadrilaterals. They define different parts of a quadrilateral shape.

Students identify the number of diagonals for each polygon. In this geometry lesson, students identify the polygons based on their diagonals and the way it intersect. They create visuals using the navigator to see the changes in the shapes.

Students identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.

Graphing by hand does have its advantages. The 19th installment of a 35-part module prompts pupils to use skills from previous lessons to graph exponential and logarithmic functions. They reflect each function type over a diagonal line...

Challenge your classes while developing their problem-solving skills. A square is divided neatly into four equal triangles by its diagonals until one diagonal is moved from a vertex to the midpoint of one side. Now, scholars must devise...

Which option involves running less? Given a situation in which players can either run around the school soccer field 20 times or run back and forth along the diagonal 20 times, learners decide which option would be better. They consider...

Programming a robot is a mathematical task! The activity asks learners to examine the process of programming a robot to vacuum a room. They use a coordinate plane to model the room, write equations to represent movement, determine the...

High schoolers discover properties of parallelograms as they construct a parallelogram using Cabri Jr. They will measure angles and side lengths of their construction and determine the relationship between the diagonals of a...

Rhombuses, rectangles and squares are have special properties. In this lesson, young geometers investigate and make conjectures about diagonals, angles, and parallel lines of parallelograms. 

Class members complete an assessment task by identifying whether statements about triangles and quadrilaterals are always true, sometimes true, or never true. They then participate in a sorting activity with the same objective.

Just how big of a TV do you need?! The task at hand asks individuals to compare the area of 80-inch and 55-inch TVs. The length of the TV is given and learners must use the Pythagorean Theorem to determine the width to calculate the areas.

Scholars explore parallelograms in this geometry lesson. They investigate the properties of a parallelogram. Assisted by technology, your learners will construct a parallelogram and examine the sides, angles, and diagonals to discover...

Students identify the different properties of quadrilaterals. For this geometry-lesson, students define parallel sides and diagonals of polygons as they compare to a quadrilateral. They identify the methods to find the angles in a...

Students solve problems using smaller steps. In this geometry lesson, students find the diagonals of rectangles and the area of the annulus between two circles. They are given the starting point and the radius.

Students begin the activity by identifying what a polygon is and hypothesizing how many struts (diagonals) it would take to make a polygon rigid. They watch a "Magic School Bus" episode then experiment with various shapes to make a...

Students identify different types of polygons. In this geometry lesson, students differentiate between convex and regular shapes. they identify the names of two and three-dimensional objects.

Students identify the properties representing quadrilateral. In this geometry lesson plan, students differentiate between special and regular quadrilaterals. They discuss and demonstrate hierarchy of quadrilaterals.

Students explore math functions by completing a worksheet in class. In this spatial movement lesson, students utilize a four square grid and a penny to practice moving the coin horizontally, vertically and diagonally as instructed....

Young biologists take a look at the myriad of ways that animals increase their chances of surviving in the wild. The adaptations help animals hide, hunt, and attract a mate. This lesson plan specifically explores how insect mouth parts...
