Product Description
These pages contain four types of activities:

1. Measuring to find the perimeter of polygons on a page. All the polygons are sized to allow practice in measuring to the nearest unit (inch or cm).

2. Measuring to find the perimeter of objects – common classroom items such as the cover of a Math book and a tabletop. All measurements are to the nearest whole inch, foot, centimeter, or meter.

3. Calculating perimeter in problems when the sides are known.

4. Calculating a side length when the perimeter is known. These activities stress the use of appropriate equations. There is also an explicit discussion of the different ways to find the perimeter of a rectangle.

Activities are sequenced in difficulty. The “Measuring to find perimeter” activities are appropriate for 3rd graders. The activities involving calculating side lengths, using equations, and solving word problems grow more difficult for many 3rd graders, but are appropriate for 4th graders. The four pages of word problems are for advanced 3rd graders and 4th graders.

Common Core Standards:

2.MD.3: “Measure the length of an object…”

3.MD.8: “Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with….the same area and different perimeters….”

4.MD.3: “Apply the area and perimeter formulas for rectangles in real world and mathematical problems…”

Subjects: Math, Basic Operations, Measurement, Equation Practice

Duration: 28 pages of student work, many problems, 2-5 days
