This activity asks the students to plot various ordered pairs on a coordinate plane and connect the points to make a polygon. Then they are expected to calculate the area and/or perimeter of each shape. The first worksheet has a square, two rectangles and a triangle. The triangle is starred to show higher level thinking. Each polygon is to be colored a different color. The second worksheet asks the students to plot the points of five polygons: a triangle, two rectangles and two composite f

This chart gives the name of each polygon, the shape, a description and the formula for finding the area of each. It is a great resource for students to put in their binder or notebook to refer to for classwork or homework. There is also an accompanying activity worksheet. I use tape to outline each shape on the floor in our hallway. Blue painters tape works best. Then the students use the Polygon Reference sheet to determine the shape of each polygon, they write the formula and then cal

Find the area of four composite figures (in the shape of a cat, train, car and rocket). FIRST, the students must plot the ordered pairs and connect to create the composite figure. SECOND, they decide in which quadrant each point lies. THIRD, they calculate the area of each figure. There is a blank page in case you want to make your own or have the students create one.

Four volcanoes are introduced through brief pieces of informational text: Mt. Vesuvius, Mt. St. Helen’s, Krakatau and Mt. Pelee. Students answer a few questions based on the reading. A map is provided for a better understanding of the location of each volcano. To reinforce the concept of ratio, students are asked to convert the elevation and base from one unit of measure to another. A ratio table is provided. To reinforce the concept of geometry (specifically the area of a triangle) student

This activity is great to integrate the concepts of graphing ordered pairs and calculating perimeter, area and surface area. Students are expected to: 1. Plot and label each ordered pair to create a rectangular prism. 2. Color in each side a different color (blue, red, yellow). 3. Label the measurement of one side (the side that can not be calculated by counting boxes). 4. Look at each colored rectangle and calculate the perimeter and area. 5. Calculate the surface area of the entire recta

Don't say good-bye to summer just yet! Problem: I just moved into a new home which fortunately has an in ground pool! Unfortunately…it doesn’t have a liner, tile around the pool, water OR a solar cover. Challenge: The pool has the following dimensions: (dimensions will vary depending on level. There are three different levels - the circle (easiest - whole numbers), the triangle (middle - tenths), and the square (most difficult-hundredths and thousandths) Draw a sketch of the pool, lab

Engage your students with this activity where they are required to build rectangles, squares and triangles out of polystrips and then calculate area and perimeter of each figure. This activity is a hands on approach which appeals to the students. I usually have them work in pairs. Materials necessary: long and short polystrips (4 of each per group), small brass fasteners, a ruler This activity allows me to reinforce: 1. Key vocabulary (vertices, sides, polygon, area, perimeter) 2.

Teach or review the concepts of perimeter and area while getting your students up and out of their seats. This activity is editable so you can change the items to measure to suit your classroom. I have used this activity to measure to the nearest whole number, 1/2 inch, 1/4 inch and 1/10 inch. It is a good way to differentiate for your students. I also like to have several types of measuring tools (small see through plastic ruler, standard one foot ruler and yardstick) to see which one the s

Reinforce ruler skills and the concepts of area, decimals and fractions with this hands on activity. Students are given three rectangles and asked to calculate the area by measuring the length and width of each shape. They are asked to calculate to the nearest 1/4 in. and show their work with both decimals AND fractions.

Reinforce the concepts of similar shapes (triangles and rectangles) through this graphing activity. Enjoy!
