2D Shapes vs. 3D Shapes

Grab a piece of paper real quick and draw a circle on it. I'll do the same here on the screen. Got your circle? Good. Now look around the room and see if you can find a ball of some sort; a basketball, baseball, even a bouncy ball will do. Now which one would you rather play with? The circle or the ball? The ball, right? You can pick it up, bounce it, throw it, or roll it. What can you do with the circle? Nothing much. You can look at it and that's about it!

You've just learned the difference between a 2D shape and a 3D shape. The circle is a two-dimensional (2D) shape. It only has two measurements, such as length and height, and is usually called a 'flat' shape. The ball, however, is a three-dimensional (3D) shape because it has three measurements (length, height, and width) and is sometimes called a 'solid' shape.

Examples of 2D Shapes

Let's see if we can find some examples of 2D shapes. Take another look around the room you're in. Can you find some of these shapes?

If you're looking for a triangle, you could go make a sandwich and cut it from corner to corner. Then you'll have two triangles! Want to find a square? Check out your picture frames or windows. To find a rectangle, go check out your television, kitchen table, desk, or even a book! If you're looking for a circle, look no further than your glass of water. The bottom and the top are probably a circle shape!

2D and 3D Figures

Three dimensional and two-dimensional shapes are present in our everyday lives. The following activities and exercises below will provide practice in creating and identifying two-dimensional shapes and three-dimensional shapes.

Materials

Popsicle sticks

Canned good

Sports ball

Box of food(doesn't have to have food in it- can be any shape)

Glue

Activity

1. Use three popsicle sticks to create a 2D triangle.

2. Use four popsicle sticks to create a 2D square.

3. Glue these popsicle sticks together and create a total of 6 squares.

4. Assemble the squares to form a 3D cube and glue the joints as necessary.

5. Use five popsicle sticks to create a 2D pentagon.

6. Use six popsicle sticks to create a 2D hexagon.

7. Can you list some additional 3D objects that represent these shapes? For example, a stop sign has a hexagon shape.

Additional Questions

1. Examine the can of food. What sort of three-dimensional shape is the can? What two-dimensional shapes make up the can?

2. Examine the sports ball. What sort of three-dimensional shape is the ball? What 2D object can represent the ball?

3. Examine the food box or packaging. What sort of three-dimensional shape is the package? What 2D object(s) can represent the packaging?

Solutions

1. cylindrical, circles are on the ends

2. sphere, circle

3. Answers will vary depending on the shape of the box and could include rectangles and/or squares.

Why is Geometry important?

The universe is built of shapes and geometry is the mathematics of it. But often the geometric field of mathematics is neglected. The importance of geometry is not realized until it gets abstract and one deal with geometry proofs examples or geometry theorems.

The field of geometry is broad and has many applications. Often, problems of other field become easier to solve when it is represented geometrically. The study of geometric relationships is used in the field of architecture and landscaping. It is seen that the many people think better visually. Geometry makes visualization logical.

Moreover, geometry connects many other fields of mathematics. For example, interpretation of bar graph involves finding the area of a rectangle. Fractions are better understood through the representation of geometric pictures. Equal sized squares are used to represent tens, hundreds, and thousands. Coordinate geometry is used to analyze algebraic relationships. Therefore, geometry is one area of mathematics that is used most widely in learning math and also other fields.

The kids are introduced to geometry math during early school years. The geometry common core math standards involve an introduction to geometry in prekindergarten. Discovering geometry helps children develop deductive problem-solving skills.

Progression of Geometry:

Related-below Grade Standard

Grade 1: In this grade, children develop skills to reason with shapes and attributes. They understand basic geometric shapes definition. They analyze shapes from their defining attributes, like number of sides. They compose two dimensional and three-dimensional shapes to make larger composite shapes. They learn to partition rectangles and circle into equal shares. They learn the vocabulary related to partitionings like quarters, fourths and halves.

Grade 2: The kids learn to identify and draw shapes according to the given attributes. They learn to draw shapes as per the specified number of faces or geometry angles. They are able to identify cubes, pentagons, hexagons, quadrilateral, and triangles. They also learn to partition a rectangle into same-sized squares. They then count these squares to determine the size of the rectangle. The kids learn to partition rectangles and circles into two to four equal shares. They describe the partitioned shapes using the geometry words like half of, third of, thirds, halves. They understand the wholes as four fourths, three-thirds, and two halves.

Related-above Grade Standard

Grade 3: The kids understand the relationship between shapes according to their attributes. They learn about the larger category shapes with shared attributes. For example, the shapes with four sides are called quadrilaterals. They partition shapes into equal parts. They learn to express the area of each part as a unit fraction of the whole. For example, they partition a shape into three equal parts and describe the area of each part as 1/3 of the area of the whole.

An Overview: Grade 2 Geometry

Attributes of shapes: The kids continue to build on their geometric understanding from grade 1. They gradually develop an analytical thinking from the descriptive thinking developed in grade 1. They learn to recognize shapes by their geometric properties. They recognize a shape by number of angles or number of sides. They also learn to use geometric words like face, edge, vertex in their descriptions.

They learn that a quadrilateral is a four-sided closed figure. The shapes like square, rectangle and trapezoid are quadrilaterals. They also learn about polygons like pentagons, hexagons and 3D shape cube.

Create and compose shapes: The kids learn to identify different polygons and also learn their names. They recognize the polygons by counting the number of sides or vertices. They learn to identify polygons like pentagons, hexagons, heptagons, octagons, quadrilaterals, and triangles. They perform activities that broaden their understanding and clarify the common misconceptions. For example, they create and compose shapes using sticks of various lengths. They manipulate and construct two-dimensional shapes on geoboards. This helps them deepen their newly learned skills.

Relate 2D and 3D geometric shapes: The kids relate two-dimensional and three-dimensional shapes. They create 3D geometric shapes using sticks or toothpicks. They create shapes like cube using sticks. They count the number of faces and the number corners of the constructed shape. They identify geometry angles like right angles formed at corners. They also learn to relate the face of 3D geometric shapes to the 2D shapes. For example, they identify the face of a cube as a square.

Partition shapes: The kids partition composite shapes and explore relationships between parts and wholes. They describe the parts as halves, thirds or fourths. They describe the wholes as two halves, three-thirds and four fourths. They use geometry puzzles like tangram to understand the composition of a shape. They manipulate the pieces of puzzles to explore different ways to compose new shapes. For example, they notice that smaller shapes can be repositioned in multiple ways to form a variety of larger shapes. For example, they use two right triangles to form a square. They form a variety of shapes like parallelogram, trapezoid, and rhombus on geometry puzzles.

The kids further explore their understanding of shapes using pattern blocks. They experiment with pattern blocks. For example, they create hexagon from six triangle shape blocks. This develops an understanding that the hexagon can be partitioned into six equal triangles. Alternatively, they realize that a trapezoid is composed of three equal sized triangles. In this case, each triangle described as a third.

A variety of partitioned shapes in different orientations is presented to kids to deepen their understanding. For example, the kids are asked to determine if the partitioned portion of a shape represents half of the figure. The kids perform various activities to understand the concept. For example, they assemble the parts to form a whole. In which, they assemble two equal parts of a circle to form a whole circle. The kids practice partitioning circles and rectangles on geoboards. The geometry lessons on partitioning circles serve as the foundation for telling time to a half hour or a quarter hour on an analog clock.

Geometry Games for 2nd Graders

Geometry games can help achieve a number of instructional goals. The games can prepare settings in which the kids visualize or create a shape. The games enable the educator to assess the how well the kids have understood a concept. It also enables them to get an impression of how kids apply their knowledge under different scenarios.

Here are two popular geometric learning games for 2nd graders:

What is tangram?

Tangram is a Chinese puzzle consisting of 7 tans or shapes. The kids have to arrange these shapes to recreate a given shape.

The rule of the puzzle requires all the shapes to be used without overlapping. Playing with tangrams help kids improve their spatial understanding. They also learn about spatial rotation skills the tracing to the opposite player. The opposite player needs to solve the picture by fitting in the 7 tans correctly. A timer can be set before the players begin placing the shapes in the outline. Whoever solves the puzzle first, wins the game. The players can also create geometry formula sheet consisting of the ways the tans are used to create any shape.

This game particularly enables kids to think critically about the shapes around them. It also develops their problem-solving skills.

Game Plot

This game requires 4 or more players and is usually played with an even number of players. The game is played in teams with each team having at least 2 players each. Before the start of the game, a bowl is filled with paper chits, which have different shapes written on them. Each team goes in turns. One player from the team will pick a chit at random. He/She will read the shape written on it without speaking it aloud. Then he or she will describe the properties of the shape to his/her team member. The team members will have to guess the name of the shape. E.g. - If the shape written on the chit is square, then the player can say that the shape has 4 sides and all sides are equal.

The team which is able to guess the shape in the least amount of time wins the game. This game particularly helps the kids remember the different characteristics of each shape. And also gain confidence in terms of communicating the knowledge gained by them as part of learning geometry.

Kids will love these hands-on 2D and 3D shapes activities. They include a variety of activities such as games and net templates. There's also a free shapes assessment.

Shapes are so fun to teach because they have such real world relevance - they are literally all around us! I've put together a collection of shapes activities which help kids learn about 2D shapes and 3D shapes.

These activities help kids to learn about 3D shapes by sorting pictures of real objects. The shapes covered include: cube, cylinder, sphere, cone, square pyramid, rectangular prism and triangular prism.

I usually begin with the sorting mats. Then the kids complete one of the cut and paste worksheets.

To mix things up, I often use hoops to sort the shapes too. I pick a few shapes to focus on, such as a cone and cube, and place these headings in hoops. Then I place the pictures of these shapes into a mystery bag. The kids pull out one picture at a time, name the shape and then place it in the corresponding hoop.

You can find out more about these activities .

I find board games awesome for small group work and math centers. I created eighteen fun games to help kids identify a variety of 2D shapes and 3D shapes. You can choose from board games or roll and cover games.

The cool thing about these games, besides the super cute pictures, is that there are games with plain shapes AND games with real objects.

You can grab the full set of these super fun board games .

I find games are a fabulous way to keep kids engaged during learning! In addition to board games, I often play shapes bingo and card games such as scoot, shape memory and snap.

You can find out more about these games here:

To help consolidate learning, I often make up workbooks using a variety of shapes worksheets. The one shown below helps kids to explore each shape individually. The pictures of real world objects help them make a connection between each shape and where they might see it in our world.

I'm one of those teachers who LOVES crafts and displays... So naturally, when creating net templates I created a cute way to display them too! The kids can make a variety of nets, which look super cute printed on colored paper. Then once they've made them, they can record the properties of the shape on the recording sheet. I'm going to make some 2D shapes worksheets in the near future too.

You can check out the 3D worksheets .

Shapes posters are a really handy reference for kids when they're completing activities or playing games. Or perhaps, when an adult accidentally forgets a shape! ;-)

I usually just pick out the posters that are relevant to the year level I'm teaching to display on the wall.

Another way I like to reinforce learning is to use shapes flashcards. I often bring out my flashcards during transitions such as before the kids are about to go wash their hands for morning tea.

You can grab this cute set of shapes posters and flashcards .

I've put together a few assessment pages which you can grab below. This resource contains a set of assessment flashcards and recording sheets.

I usually show each child one flashcard at a time and then record their answers on the recording sheet as we go along.

You can grab your free copy of the shapes assessments by clicking the download button below.

I hope you find these resources helpful.

Happy teaching! :)

Ideas for teaching shapes

# data[].attributes.attachment_link.readable_text
Are you looking for fun and creative ways to teach shapes? These 2D and 3D shapes activities will send your engagement factor soaring as your students learn, sing, and write about 2D and 3D shapes and their attributes.

Shapes and geometry... two of my favorite math units to teach. There are so many creative ways to teach about shapes, and let's face it, it's a whole lot more FUN than teaching primary students to decompose, regroup, and subtract across zeros! Read on for lesson ideas and see how I sent my kids over the top by changing the words to a viral video, What Does the Fox Say?.

Get students up and moving

Get your students up, moving and dancing to What Does the Fox Say? But change the words to What does the SHAPE say! to the delight of my class I used this video to introduce our unit.

Use an Anchor Chart as a Game Board

Create an interactive What Does the SHAPE Say? anchor chart that serves as a lesson visual AND a game board. You can easily adapt it to teach plan or solid shapes and their attributes.

We use the chart parts to also play a whole group version of I Have, Who Has for students to identify shapes and their attributes.

Include Fun Read Alouds

Practice ELA Skills Using Math Content

Depending on your grade level you can easily differentiate by choosing the vocabulary, length, and complexity of your students' writing.

Animate Your Writing Using ChatterPix

Turn Your Talking Shapes Into a Class Math Movie

To make the movie I saved each student's work from Chatter PIX in Dropbox then uploaded them into iMovie. You can then add a title and select from their music library or even add your own song. We used the karaoke version of What Does the Fox Say? that I purchased on iTunes.

Munch On Shapes During Math Class

Check the dollar store first when looking for crackers. They almost always have all the shapes you'll need.

Quote Quadrilaterals

The year before we did a variation on our fox crafts by quoting quadrilaterals. Literally no prep, students draw a quadrilateral on construction paper, cut it out, and add wiggly eyes. They then use quotation marks to quote the quadrilateral!

Our shapes unit was such a hit I made a similar one for teaching time to the hour/half hour, quarter hour and nearest 5 minutes. CLICK HERE for fun ways to teach time.

Happy teaching!
