Hence, the second rectangle has a larger area than the first one.Įxample 2: Alex wants to create a rectangular photo frame that has a boundary length of 10 feet. The diagram below has the same perimeter, 14, but the area will be different: Perimeter of the rectangle = length + width + length + widthĪrea of the rectangle = length (l) \(\times\) width (w) Make a different rectangle with the same perimeter as the first. You can also find her on Facebook and Pinterest.Example 1: Find the perimeter and area of the rectangle. She is a former public elementary teacher, and has recently begun blogging at her page You’ve Got This. Rachel is a homeschool mom to four little ones, ages 2 to 6. The first person that correctly completes one of their challenges wins. (If they do not want to use a certain colored rod they can put it back in the pile.) When they’re able, they use their rods to help them complete a challenge. Players continue rolling and moving around the board until they have enough rods to complete a challenge. Note: if they land on green, they may choose either of the green rods. Whatever color they land on is the color of the Cuisenaire rod they may pick up. Next, students roll a die and move that many spaces.

Gather up game markers, a die, and Cuisenaire rods (for this game, the students will only use the green rods, purple, yellow, blue, and red rods.)ĭirections for the Hands On Area and Perimeter Game:įirst, students draw two to four challenge cards (decide how many before you begin-you could also use just the perimeter or just the area challenges if you’re focusing on one or the other).

Print off the challenge cards and cut out ( laminate for durability).

When they can successfully build the shapes, they are ready for the game.

How about two rectangles with an area of 24?.

Now try making a rectangle that has a perimeter of 12?.

Can you make a square that has an area of one?.

Can you make a rectangle that has a perimeter of four?.

If they struggle with this, have them create equations before they even start with the rods: So they could make a right triangle, or they could create a rectangle with a triangle in it.)Īfter they are understanding that, it is time to increase the difficulty. What is the perimeter? What is the area? (If this is appropriate for your children, you may have to remind them that they have to know the height.

Make a rectangle out of two whites and four reds? Now, what is the area and what is the perimeter?.Here are some fun area and perimeter challenges to get them used to creating and exploring area and perimeter with the rods: It may also help them to be reminded that you find the area by multiplying the base times the height, and the perimeter by adding up all the sides. Yet in this example, because the rods are not overlapping, the child has made a rectangle that is 5 by 4:ĭepending on the needs of your kiddos, you may want to start off with the very basics. In this example, the child has made a rectangle that is 4 by 3: It is important to state here that you can actually get different areas and perimeters, even while using the same rods. Next, the children need some time to explore area and perimeter with the rods. It may even be helpful to create a chart as a “cheat” sheet.

Now it is easy to see that the white equals one, the red two, the light green three and so on. Now it is time for some math, and a good place to start is with the value of each rod.īegin by having them line up the rods in order from shortest to tallest. Second, even if they are just playing with them, they are making observations and connections that will help them when it is time to get to work. Allowing them to just “play” with them first has benefits.įirst, they are more likely to pay attention to you when they aren’t thinking about how long before they can get their hands on the manipulatives. Most children love new materials, and they can’t wait to see what they can do with them.

One of the best ways to start with new manipulatives is to let the children explore. If your children have not played with Cuisenaire Rods before, a little intro will help them be successful with the game. This is a guest post from Rachel of You’ve Got This Math. * Please Note: This post contains affiliate links which help support the work of this site. There are so many hands-on ways for children to explore and create with this topic.īut like all math concepts, practice is needed….and this fun, STEM inspired Area and Perimeter Game is a great way to get some practice in. Teaching area and the perimeter of shapes isn’t any different. It is easy to pull out the manipulatives and let children explore, build, and be creative.
