 Standard 4 - Measurement The student will apply appropriate tools and units of measurement to produce reasonable results Level 1 estimate the area of irregular geometric figures on a grid Square Skate - Divide this figure into four identical parts (of the same shape and size) which may form the square as shown in the figure. Other geometric dissections on the web - A geometric dissection is a cutting of one or more figures into pieces that can be rearranged to form other figures. Dissections are often cast as puzzles, in which the object is to use as few pieces as possible. These geometrical puzzles fall under the category of mathematical recreations calculate rates involving cost per unit to determine the best buy (no more than four samples) Global Grocery List Project - Students share local grocery prices to build a growing table of data to be used in social studies, science, health, mathematics, and other disciplines. Uncle Vito's New York Pizza has an online menu and sizes all in one place. This would be a good source of data to practice unit cost. apply the given formula to determine the area or perimeter of a rectangle Level 2 apply the given formula to find the area of a circle, the circumference of a circle, or the volume of a rectangular solid Area and Volume from Ask Dr. Math - A simple way to think about area and volume Areas of Triangles, Trapezoids, and Kites - discover or demonstrate the formulas for the areas of triangles, trapezoids, and kites. (three activities) Challenge Exercises: Area of a Circle Circle Calculator - Cylinder Calculator - Sphere Calculator Circle, Sphere & Cylinder Calculator [This expired page is from the Internet Archive known as the Wayback Machine.] Estimating How Much Your Fish Weighs - two suggestions that depend upon figuring out the volume of a fish ( A free site that may occasionally exceed its allocated data transfer How Are Things Shaping Up? Investigating Surface Area, Volume, and Properties of Shapes Introduction To Volume This lesson is a pure text document, but outlines an interesting experiment using popcorn. Lesson on Circumference of a Circle Level 3 select the area representation for a given product of two one-variable binomials with positive constants and coefficients Sample Task Place students in small groups giving each group a different length of string. Have each group form a rectangle with the string. Ask each group to measure the sides of their rectangle and find its area. Using the string, direct each group to construct the rectangle with the greatest possible area. Give each group the opportunity to justify their solution.
