Learning 3D shapes is an important part of kindergarten math. 3D shapes have three dimensions: length, width and depth. They are also called solid shapes because they take up space. Some examples of 3D shapes are cubes, cones, cylinders and spheres.
Kindergarten can learn to recognize and describe these shapes by their faces, vertices and edges. A face is a flat surface on a 3D shape, a vertex is a point where two or more edges meet, and an edge is a line where two faces meet. For example, a cube has six faces that are all squares, eight vertices and twelve edges. Kindergarten can use different activities to explore 3D shapes, such as sorting them by their properties, building them with blocks or clay, or finding them in real life objects.
Learning 3D shapes is important to kindergarten for many reasons. Here are some of them:
It helps children identify and organize visual information in their environment. They can recognize shapes in objects, signs and symbols around them. For example, they can see that a stop sign is an octagon, a door is a rectangle, a roof is a triangle and a wheel is a circle. They can also see that some objects have 3D shapes such as spheres, cubes, cylinders and cones.
It helps children learn skills in other curriculum areas such as reading, math and science. They can use shapes to compare, sort, classify, measure, pattern and create. For example, they can use shapes to make words or sentences by arranging them in different ways. They can also use shapes to solve problems or perform calculations by counting their faces, edges or vertices. They can also use shapes to explore concepts such as symmetry, volume or surface area.
It helps children boost their creativity and artistic development. They can make better paintings and craft items with some knowledge of 3D shapes. For example, they can use 3D shapes to make sculptures or models of animals or buildings. They can also use 3D shapes to draw realistic pictures with perspective or shading.
It helps children improve their visual skills and spatial awareness. They can form mental images of 3D shapes from multiple perspectives and understand how they relate to each other. For example, they can imagine how a cube looks like from different angles or how it changes when it rotates or flips. They can also imagine how different 3D shapes fit together or stack on top of each other.
Some necessary things to teach kindergarten about 3D shapes are:
The vocabulary of 3D shapes, such as cube, cone, cylinder, sphere, face, vertex and edge. These are words that describe the names and features of 3D shapes. A cube is a 3D shape that has six square faces, eight vertices and twelve edges. A cone is a 3D shape that has one circular face, one vertex and one curved edge. A cylinder is a 3D shape that has two circular faces, no vertices and two curved edges. A sphere is a 3D shape that has no faces, no vertices and no edges. A face is a flat surface on a 3D shape. A vertex is a point where two or more edges meet on a 3D shape. An edge is a line where two faces meet on a 3D shape.
The difference between 2D and 3D shapes, such as flat vs. solid. 2D shapes are shapes that have only two dimensions: length and width. They are also called plane shapes because they lie on a flat surface. Some examples of 2D shapes are circles, squares, triangles and rectangles. They have no thickness or depth. 3D shapes are shapes that have three dimensions: length, width and depth. They are also called solid shapes because they take up space in all directions. Some examples of 3D shapes are cubes, cones, cylinders and spheres.
The properties of each 3D shape, such as how many faces, vertices and edges they have. The properties of each 3D shape are the features that help us identify them by their shape and size. One property is the number of faces they have. A face is a flat surface on a 3D shape. For example, a cube has six faces that are all squares. Another property is the number of vertices they have. A vertex is a point where two or more edges meet on a 3D shape. For example, a cone has one vertex at the top where the curved edge meets. Another property is the number of edges they have. An edge is a line where two faces meet on a 3D shape. For example, a cylinder has two edges where the circular faces meet the curved surface.
The examples of 3D shapes in real life objects or foods . There are many examples of real life objects or foods that come in different shapes like cubes, cones, cylinders and spheres. Some examples are:
Cubes: dice, Rubik’s cube, cheese cubes, sugar cubes.
Cones: ice cream cones, traffic cones, party hats, pine cones.
Cylinders: cans, bottles, candles, cheese sticks.
Spheres: balls, oranges, marbles, planets.
There are many ways to teach kindergarten about 3D shapes. Kindergarten can use different activities to explore 3D shapes, such as sorting them by their properties, building them with blocks or clay, or finding them in real life objects.
Use a chant to introduce and review the vocabulary of 3D shapes, such as solid, flat, corners, faces and edges. Make hand motions to show the features of each shape. One example of a chant is:
3D shapes are fat not flat
A cone is like a party hat
A sphere is a bouncy ball
A prism is a building tall
A cylinder is like a can of pop
A cube is like the dice you drop
Have kids snack on foods that come in different 3D shapes, such as cheese cubes, ice cream cones, cheese sticks and oranges. Have them sort them, name them and then eat them. This activity helps kids recognize 3D shapes in real life objects and foods. It also helps them practice their sorting and naming skills. You can also ask them questions like:
How many faces does this shape have?
How many vertices does this shape have?
How many edges does this shape have?
What other foods or objects look like this shape?
Use manipulatives such as blocks, clay or toothpicks to build 3D shapes. Have kids count how many faces, vertices and edges they have. This activity helps kids explore the properties of 3D shapes by creating them with their own hands. It also helps them practice their counting skills. You can also challenge them to make different combinations of shapes or to make patterns with shapes.
Play a “Who Done It” game where one of the 3D shapes has committed a crime. Have kids ask yes or no questions to find out which shape it is based on its properties. This activity helps kids use their logical thinking and deductive reasoning skills to identify 3D shapes by their features. It also helps them practice their questioning skills. You can also make it more fun by adding clues or suspects to the game.
Here are some steps for kindergarten to learn about 3D shapes:
Introduce the concept of 3D shapes by showing them some examples of real objects that have 3D shapes such as balls, boxes, cans and cones. Explain that 3D shapes are solid and can be held in their hands.
Teach them the names and features of some common 3D shapes such as sphere, cube, cylinder and cone. Use a chant or a song to help them remember the vocabulary: solid, flat, corners, faces and edges. Make hand motions to show the features of each shape.
Show them how to identify 3D shapes by their faces. Explain that faces are the flat surfaces on a 3D shape. For example, a cube has six square faces, a cylinder has two circular faces and a cone has one circular face. Use flashcards or posters to help them recognize different faces.
Show them how to sort and classify 3D shapes by their attributes. For example, they can sort them by the number of faces, edges or corners they have. They can also sort them by whether they have curved or flat surfaces. Use sorting mats or trays to help them organize their shapes2.
Show them how to compare and contrast 3D shapes by their similarities and differences. For example, they can compare a sphere and a cube by saying that they both have one color but different numbers of faces. They can also contrast a cylinder and a cone by saying that they both have circular bases but different heights. Use Venn diagrams or charts to help them compare and contrast their shapes.
Show them how to make models or drawings of 3D shapes using different materials such as clay, paper, straws or toothpicks. Explain that they can use these materials to make the faces, edges or corners of each shape. For example, they can use clay to make spheres or cubes; paper to make cones or cylinders; straws to make edges; toothpicks to make corners. Use templates or guides to help them make accurate models or drawings.
