If you are working to address area & perimeter in your third grade classroom, start with this free collection.
This set of resources was designed to help with your instruction for area and perimeter, but also to give your students practice with the concepts. It is intended to address third grade geometric measurement standards.
All of the resources described below can be found in one download at the bottom of the post.
Anchor Chart – A visual to help with your instruction and for student reference throughout the unit. (We have also provided a blank chart with a border in case you want to create something of your own to match the resources in this collection.)
“I Can” Standards – These “I Can” standards can be used to post in your classroom so students understand the learning outcomes for third grade area & perimeter.
Center Signs – These half sheets can be used as directions for a center that includes our resources, larger shapes you cut out or items from your classroom.
Area & Perimeter Interactive Notebook Page – Students cut around the dark lines of the page, glue the center strip of the page to their notebooks and then cut the horizontal dark lines to create flaps. Under the flaps the students can record the area or the perimeter of the shapes as you direct them. In the center, have students write if they are to find the area, perimeter or both. This is also a good spot for students to record the formulas.
Area & Perimeter Task Cards & Recording Pages – This set of 12 cards can be used during a small guided math group or as a center. They can be used with area or perimeter (with a little direction from you about labeling the side lengths of the sparkly shapes by counting the squares to determine the length of the side). We have also provided two different recording pages – one with six boxes and one with eight so that you can differentiate the number of tasks you want specific students to complete.
Idea for Introduction to the Formula for Area – To help students begin to understand the concept that area = length times width (A = l x w) one idea is to cut out several 1-ft by 1-ft pieces of construction paper. You might want to laminate these for durability so that you can use them again and again. (Be sure to have enough squares to measure the entire length of the longest wall of the room you will be measuring. Also, this initial lesson will work best if your classroom is the shape of a square or rectangle. If not, you may want to take your class to a room or area of your building that is.) Divide students into problem solving groups of four or five, and then ask them to think about how they could figure out the area of your classroom floor. After the initial instruction you have given on area, hopefully some groups will come to the determination that unit squares would need to be placed all over the floor of the classroom. Tell them that you don’t have enough squares for that and ask them to problem solve how they might determine the number of squares it would take to cover the floor without actually doing it. Gather your students and ask groups to share their ideas. Then, with some guidance (if needed) help them to conclude that they only need to measure two walls of the classroom to figure out how many would be needed to cover the floor. (This may take some additional problem solving as a class.) Together use the construction paper squares to line one wall and then a perpendicular wall to come up with the lengths of each. Next, take the lesson a step further by discussing the addition and multiplication that could occur to figure out the area of the floor. Relate your findings to the formula A = l x w and generalize by applying it to some shapes you draw on the board.
Area Practice Pages – We have created two beginning area pages you can use for student practice or assessment.
Area Squares & Recording Pages – While many of you may already have plastic square tiles as math manipulatives in your classroom, we realize not all teachers have access to some. For those people we have created simple sheets of squares that you can print on card stock, laminate and cut out (blue and white sets are provided). Place these in baggies and have students use them to measure the areas of various surfaces in the classroom (tops of desks or tables, books, rugs, etc). This is a great hands-on idea and really helps some students grasp the concept of area.
You can also have your students use rulers or yardsticks to measure the perimeter of things around your classroom. We have provided recording pages (for both area and perimeter) where students can list the names of the classroom items they are measuring and write the measurement. (Be sure they understand the concept of square units for the area measurements.)
Area & Perimeter Blank Books – With these pages you can create books with as many pages as you would like for your students. They find items in the classroom, draw and label the pictures with measurements and determine the area of perimeter. This can be a very engaging activity for students. If you feel some of your students might struggle, think about having them work in pairs for this activity.
Make-a-Shape Pages – These four pages require students to draw shapes and measure them to determine their area or perimeter.
Distributive Property Booklet – Though the concept of using the distributive property to help determine area can be a bit more easily understood in hands-on experiences (breaking down shapes into smaller shapes, measuring the area of those and then adding the measurements), many standards require students to also use the distributive property as a formula (side lengths a and b+c is the sum of a x b and a x c). Sometimes this can be a bit more confusing. To help students understand this better we have created a booklet that you can work through with your class or small group.
Area Task Cards – This set of task cards contains six simple shapes and six shapes that will require students to use the distributive property to solve them. (You can use the recording sheet from the above set of task cards with this set as well.)
Use the Formula for Area Practice Page – Unlike the previous practice pages, the shapes on this page do not show the square units. Students will need to use the labeled sides and the formulas they have learned to determine the areas.
Exit Tickets – These simple exit tickets can be used as a quick assessment to see if your students have learned the concepts of area and perimeter.
