Students love the gamified review, and you will love having pre-prepared materials! A Perimeter, Area, and Volume Scavenger Hunt Win-win!Įven in 4th grade I would make the perimeter of a polygon stations available for students to build confidence.Īnother way to use these math stations is in small group or with a tutoring group. This allows students to work independently of the teacher and see the concept in as many different ways as possible. In order to build towards mastery, I created sets of math games, or stations, that have ten different partner games on the same set of skills. Throughout the unit, I like to keep the review going!įor this, I have found no better and more engaging way than using partner math games. Practice with Perimeter, Area, and Volume Math Games Students must then do the math to determine the length of the sides of their shape before creating it. If you want to offer a further challenge, before students create their shape assign them a perimeter. Start by giving students a few minutes to create their shapes and then proceed as before with students measuring and finding the perimeter of each shape. On the other hand, you could have students create the shapes. Students then use a ruler or other measurement tool to travel around the room completing measurements and finding the measurement of each figure. You could also tape these figures on the walls or whiteboard, really wherever you have open space. I personally used masking tape, for easy removal, and taped various shapes on the floor around the room.
The first is for you, the teacher, to pre-tape the shapes. There are two ways to complete this activity. This skill is then built upon in subsequent grades including using a formula to solve for the perimeter of regular shapes.įinding the perimeter of floor shapes is the perfect way to practice this skill! This is one of my very favorite strategies for introducing and practicing perimeter!Īccording to the TEKS students in 3rd grade should be able to find the perimeter of a polygon, including measuring the sides. By showing our students problems and concepts in different ways they are able to build to mastery. While each of these activities in and of their own will be sure to thrill your students, the power of them is repeated practice of the concepts in different ways. This would mean that the regular octagon would have greater area than the regular hexagon but less than the circle.Perimeter, area, and volume can be a difficult set of concepts to teach, but they can also be a lot of fun! In this blog post, I will be detailing five of my favorite activities for practicing and reviewing perimeter, area, and volume. It is reasonable to conjecture, based on this evidence, that as the number of sides of the regular polygon with perimeter one unit increases so does the area. $$ The triangle with perimeter one unit has the smallest area, followed by the square, then the hexagon and finally the circle. For example, of all triangles, the one with fixed perimeter \(P\) and largest area is the equilateral triangle whose side lengths are all \(\frac. Only three shapes are considered here because the problem is difficult for more irregular shapes.
This problem is part of a very rich tradition of problems looking to maximize the area enclosed by a shape with fixed perimeter.
