![]() It’s a 2-dimensional figure whose name is based on the number of its sides. Explain that a polygon is a closed plane figure, formed by connecting segments that are called ‘sides’. These properties make each 2-dimensional figure special, while there are also some that share common characteristics.Īdd that one example of 2-D figures are polygons. Point out that there are many 2-dimensional figures around us and that each of them has its own unique properties. If students understand the difference between 2-dimensional and 3-dimensional shapes, they should be able to recognize that the cylinder and rectangular prism have height in addition to length and width, and are not flat, hence they’re not 2-dimensional objects. ![]() While 2-dimensional shapes are flat figures with length and width, 3-dimensional shapes are solid figures with length, width, and height.ĭraw an example on the whiteboard where there are both 2-dimensional figures and 3-dimensional figures and ask students to circle the 2-dimensional ones. You can draw a distinction between the two to make things clearer. Students have also encountered 3-dimensional shapes. You can include shapes such as the following: If you have manipulatives or images, even better. ![]() Add that there are many different 2-dimensional shapes and draw examples of such shapes on the whiteboard. It is a flat plane figure that has no depth or thickness.īy now, students have come across many 2-dimensional shapes. Explain that a 2-dimensional shape (or a 2-D shape) is a shape that only has two measurable dimensions – length and width. Ideas for Teaching 2-Dimensional Shapes and Their Properties What Are 2-Dimensional Shapes?įor starters, define what 2-dimensional shapes are. Use them in your class and see students’ math knowledge soar in no time! Lessons on 2-dimensional shapes can be lots of fun if math teachers are equipped with the right resources! To this end, we bring you a few teaching ideas and awesome activities on this topic. They gain an in-depth understanding of what these shapes represent, and learn how to identify their properties. In grade 5, students learn about the different 2-dimensional shapes, such as circles, squares, triangles, etc.
