Let's explore types of solid shapes-Ī sphere is a solid shape, absolutely round in shape, defined in three-dimensional space. These occupy some space, have length, width as well as height. Look around! Every other three-dimensional object, be it a laptop, cellphone, an ice-cream cone, balls, etc, are examples of solid shapes. Grow student confidence in mathematics with HMH Into Math, our core math solution for Grades K–8.Solid shapes correspond to three-dimensional objects. When children create or find patterns, they are using the attributes of not just one but of a series of shapes to determine the order or pattern. Once children can recognize and describe the attributes that distinguish plane and solid shapes, such as those that make a triangle different from a square or a cylinder different from a cone, they can begin to create and continue patterns. You can also look for printouts that let students construct 3-D shapes or have students create cubes, pyramids, and other solid shapes using toothpicks and marshmallows. Look online for folding ideas, such as creating a cube. Origami presents an exciting way to transform a flat plane shape into a solid shape.Look for buildings near the school and around the world with interesting shapes or balls from sports that your students like to play. Have students identify solid shapes in the real world! Either bring objects, such as an ice cream cone, number cube, or soccer ball, for students to describe and classify, or have students look for objects outside of school to share.Does your school have access to a 3-D printer? Don’t just describe shapes like cubes or spheres-actually create them! Present the 3-D printed objects to the class and have them share what they notice and wonder.For students who are ready, you may want to show how the faces of cubes and rectangular prisms must meet at right angles, or all the points on a surface of a sphere are the same distance from a central point.(But some cylinders will slide more easily than others!) A cylinder, on the other hand, has two circular faces, so it can both roll and slide. For example, a child might see that although both a cylinder and a sphere can roll, a sphere has no faces and cannot slide. This will enrich the ways in which they can describe and compare solids. Tracing around the face of solids will help a child understand a cube differs from a rectangular prism because all six of its faces are squares. Because of this, it is common to teach solid shapes first before moving on to plane shapes, which we practice in HMH Into Math. This is an important idea, as the real world around us is three dimensions and made of solid shapes! The place where people see flat plane shapes is generally on the faces of 3-D objects. They will also come to see how the plane shapes comprise the faces of solid shapes. (Grade K)Īs with plane shapes, children will learn to describe solid shapes in terms of their attributes. Key standard: Analyze and compare two- and three-dimensional shapes, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”), and other attributes.A side is a straight line that makes part of the shape, and a corner, or vertex, is where two sides meet. Different plane shapes have different attributes, such as the number of sides or corners (or vertices). A closed two-dimensional, or flat, figure is called a plane shape. Most of the objects that we encounter can be associated with basic shapes. They can apply these same terms when describing plane and solid shapes in the classroom. Terms like above, below, left, right, or between enable children to orient themselves with their surroundings and describe the world around them. Understanding an object’s position in space and learning the vocabulary to describe a position and give directions are important.
