New! Family Activity: Triangles and Quadrilaterals
6th - 8th
In this triangles and quadrilaterals worksheet, students solve 7 short answer problems. Students find objects around the house that are constructed from triangles, parallelograms, trapezoids, squares, rectangles. Students sketch the object on their paper.
Areas of Triangles, Parallelograms, Trapezoids
Students use index cards to record and math the formulas for area of triangles, parallelograms, and trapezoids. For this area lesson plan, students also complete a worksheet provided.
Finding the Area and Perimeter of Polygons
Seventh graders practice finding the area and perimeter of polygons. In this polygon area lesson, 7th graders brainstorm shapes and take a walk to locate shapes. Students record properties of shapes and use various shapes to make a polygon. Students practice finding formulas for the area of a square, rectangle, triangle, parallelogram, and trapezoid. Students complete to problems by maximizing area with a given perimeter.
Finding the Area of Shapes
In this area of shapes unit, upper graders participate in hands-on problem solving activities to find the formulas for the area of a parallelogram, a triangle, and a trapezoid. They manipulate the geoboard to explore relationships among various shapes and their areas.
In this area worksheet, students solve and complete 20 different problems that include the measurement of various figures. First, they determine the area of each of the triangles, parallelograms and trapezoids. Then, students determine the area of each of the shaded regions in the figures shown.
Developing Formulas for Triangles and Quadrilaterals
In this geometry worksheet, 10th graders determine the area of triangles, parallelograms, trapezoids, kites, and rhombuses. The one page worksheet contains eleven problems. Answers are included.
Does the Area of the Quadrilateral Change?
Seventh graders complete activities to further their understanding of area formulas. In this area instructional activity, 7th graders watch as the teacher uses Polystrips to model parallelograms. Students find the area of a rectangle and answer questions about the equation. Students work as a group to solve a parallelogram problem.
Unit of Measures used in Measuring the Area of a Triangle/Parallelogram
Third, fourth, and fifth graders explore area measurement. First, they define and identify parallelograms. They then construct parallelograms on a geoboard and determine the area by covering it with paper square centimeters. They also solve story problems about area using the geoboard.
Area and Perimeter of Figures
In this area and perimeter worksheet, 10th graders solve 10 different problems that include various figures shown. First, they determine the area of triangles, parallelograms, and trapezoids in each box. Then, students determine the perimeter of each triangle, parallelogram and trapezoid illustrated.
Learners explore a variety of geometric shapes, name them, and list their characteristics. The shapes are transposed into structures and checked for accuracy.
Hula Hoop Sorting
First graders use two large hula hoops to form a Venn Diagram. Then, using various colored paper shapes, they recognize, and identify circles, squares, triangles, rectangles, hexagons, trapezoids, and parallelograms.
