Geometry and Measures 7: Circles and Triangles

Year 6 area of rectangles, squares, triangles and circles using metric system

Let's Make Shapes! A line connects two points. A line is longer than it is wide. Lines can be short, and lines can be long. Lines can be straight, and lines can be curved. You can bend lines to make a shape. You can join straight lines together to make a shape. You can join curved lines together to make a shape. There are many kinds of shapes. Circles, squares, rectangles, and triangles are geometric shapes. We can use geometric shapes to draw many things. When a line goes all the way around, it makes a circle. You can use a circle, three small circles, and a curved line to make a face. On another piece of paper, draw a circle. Then make it a mouse with eyes, ears, and whiskers. Use lines and more circles. If we cut a circle in half, we get two half-circles. You can use four half-circles to draw a caterpillar. On another piece of Then make it into a fish paper, draw a half-circle. with eyes, a tail, and fins. When a line turns a corner three times, it makes a triangle. Triangles have three sides and three corners. You can use triangles to make a face on a pumpkin. On another piece of paper, Then make it into a tree draw a triangle. with leaves and a trunk. When a line turns a corner four times, it makes a square. A square has four sides and four corners. Each side is the same length. You can use squares and half-circles to make a truck. On another piece of paper, draw a square. Then make it into a dog by adding ears, a tail, and legs. Use curved lines and straight lines. A rectangle has four sides, just like a square. Two sides are the same length. The other two sides are another length. You can use rectangles, circles, squares and lines to draw a bus. On another piece of paper, draw a rectangle. Then make it a house with a roof, two windows, and a door. Use a triangle and three rectangles. Now, on another piece of paper, make a picture using all of the shapes: circles, squares, triangles, and rectangles.

Area of Circles, Rectangles and Triangles

The Ship of Shapes One day, Elder Decagon saw that the shapes on Shape Island had become lazy. They sat in their huts, fanning themselves until it was time to eat. The different shapes didn't like to spend time with each other. The Rectangles stayed with the Rectangles, the Circles with the Circles, and so on. Elder Decagon came up with a plan. "Oh, oh, oh!" she exclaimed. Worried, the shapes gathered around her. "Big Scary Fire Mountain just spoke," she said. "It will erupt soon, and all our pants will be on fire." "We must leave the island!" The shapes were confused and scared. "Didn't you hear me?" "Pants will be on fire!" Elder Decagon yelled. "What should we do?" the shapes asked. "You should build a ship," she said very slowly. The shapes cheered for the great idea and hurried off to begin. The next day, Elder Decagon was surprised to see many ships on the beach. Each ship was meant for only one kind of shape. "None of these ships are shipshape, she said. "The Triangles' boat will tip in the water." "The Ovals' ship will float, but it won't move." "The Squares' ship will move, but too slowly." "What should we do?" the shapes asked. "You should build one big ship," Elder Decagon said very slowly. This time, the shapes didn't cheer. They weren't sure how to work together. Elder Decagon picked up a stick and started to draw. She showed them how the Squares sails would move the Ovals' boat. The Triangles' bottom would keep it from tipping. The Stars' propeller and the Hearts oars would help the ship move faster. In the end, all of the shapes went into the ship. The shapes stared at the drawing, but no one moved. "Pants will be on fire!" Elder Decagon yelled. The shapes went to work. When it was finished, all the shapes climbed onto the ship. They waited for Big Scary Fire Mountain to erupt, but it never did. The shapes asked Elder Decagon why it didn't. She just said, "Look at this wonderful, shipshape ship." "It shows that if you work hard together, you can go anywhere and do anything.' After some thought, the shapes agreed. They decided to work together to make Shape Island a better place. They also decided to explore the seas in their shipshape ship.
