Begin from the inside and work outward. Pupils construct quadrilaterals based upon the descriptions of the diagonals. Pairs then work through several configurations of diagonals and determine the types of quadrilaterals they can form....

Work the problem shown in this video to learn how to determine the area of a parallelogram. Basic algebra, area, and the Pythagorean Theorem are used to find the missing value and solve the problem of area.

The quadrilateral is a very interesting shape. Have your class construct midpoint quadrilaterals within quadrilaterals on their Ti-Nspire. They measure the length and angle measures of sides and angles of the midpoint quadrilateral. Full...

Scholars examine six common quadrilaterals and identify each by writing its name beneath the shape. Next, they sketch four shapes: parallelogram, rectangle, rhombus, and trapezoid. Once finished, review which features helped learners...

Young scholars explore geometry by identifying different shapes. For this quadrilateral lesson, students define several geometric shapes such as trapezoid, rectangle, and squares. Young scholars identify their characteristics and...

Upper graders and middle schoolers find the area of nine polygons. They find the area of triangles, parallelograms, and irregular polygons given a sketch of each figure on grid paper.

If you like to start each day with a new math challenge or warm-up, this resource is a must have. It includes 36 slides, each containing a different math challenge that stimulates algebraic reasoning, problem solving, and basic math...

Fourth and fifth graders work in pairs  explore quadrilaterals. In this problem-solving lesson plan, learners participate in hands-on activities that require them to identify, describe, compare, and classify quadrilaterals. This is meant...

Young geometers take a look at a variety of shapes and name each one. All of the shapes are quadrilaterals, and they all have intersecting diagonal lines running through them. This presentation would be good to use as an introduction to...

In this geometry instructional activity, learners use a diagram to complete a chart of angle measures and solve 4 related problems. Houghton Mifflin test is referenced.

In this identifying quadrilaterals and angles true and false worksheet, learners review sides and angles of a quadrilateral, parallelogram, trapezoid, rectangle, rhombus, and square and write true and false answers to statements....

Students solve single step and multi step word problems where they calculate the perimeter of quadrilaterals. In this perimeter lesson plan, students go over word problem steps to find the answers. This could easily incorporate...

Tenth graders classify quadrilaterals graphed on a coordinate plane. In this geometry lesson, 10th graders classify quadrilaterals based upon side length, angle measures, parallel or perpendicular sides, and diagonal relationships. The...

Students classify quadrilaterals, In this quadrilaterals lesson, students watch a video about parallelograms, discuss the different types of quadrilaterals, and complete a worksheet classifying quadrilaterals.

Young scholars identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

Working on symmetry in your class? If so, this worksheet might be for you. Learners observe different triangles and quadrilaterals, determine which are symmetrical, draw in the lines of symmetry, and color the symmetrical shapes. In...

This resource provides 5 different worksheets on the topic of polygons and symmetry. These worksheets cover rotational symmetry, lines of symmetry, symmetry of regular polygons, special quadiralaterals, and polygon transformation. The...
