# Activities to Teach Students About Regular and Irregular Polygons

Polygons are two-dimensional shapes that have straight sides and angles. They are an essential part of geometry and come in different shapes and sizes. In particular, polygons can be classified into two types: regular polygons and irregular polygons. Regular polygons are shapes that have equal sides and angles while irregular polygons have sides and angles of varying lengths and measures. Teachers can use different activities to teach students about regular and irregular polygons.

Name the Polygon Game:

In this game, students can work in pairs or small groups. Teachers can display various polygons on the board, and students have to determine whether the polygon is regular or irregular. They can take turns naming the polygon and stating whether it is regular or irregular. Teachers can also ask students to explain how they know if the polygon is regular or irregular.

Polygon Sort:

Teachers can provide students with sets of regular and irregular polygons, cut out from cardboard or printed on paper. They can then have students sort the polygons into two different categories, discussing their observations and explanations. This activity can also be done digitally using online resources such as Google Slides or Jamboard.

Polygon Building:

Students can work in groups or individually to create different polygons using sticks, straws, or craft materials. Once they have created the polygons, they can analyze and compare their shapes to determine which ones are regular and which ones are irregular. They can also measure the sides and angles of each polygon to check if they are the same. This activity allows students to explore the properties of polygons in a hands-on way.

Polygon Drawing:

Students can draw different regular and irregular polygons using grid paper or interactive online tools such as Geogebra. Teachers can provide a set of instructions to follow when drawing a specific polygon. Once the polygons are drawn, students can identify and label the angles and sides. They can also compare the angles and sides of regular and irregular polygons.

Polygon Puzzles:

Teachers can provide students with polygon puzzles that require them to solve problems related to regular and irregular polygons – such as finding the perimeter, area, or missing angle measurements. Teachers can also create a crossword puzzle with terms related to polygons or a word search that includes the names of different polygons.

In summary, there are many different activities that teachers can use to teach students about regular and irregular polygons. These activities allow students to develop their geometric thinking and deepen their understanding of the properties of polygons. By providing hands-on experiences with these shapes, students can better visualize their attributes and develop critical thinking skills.
