Polygons are closed, two-dimensional shapes made of straight line segments. Think of them like connecting the dots, but the last dot has to connect back to the first one! These shapes can have many sides and angles. We are going to work on some fun activities to identify different polygons!
In fourth grade, we usually focus on understanding and identifying polygons such as triangles, quadrilaterals (like squares and rectangles), pentagons, and hexagons. Let's get started!
Match each term with its correct definition:
| Term | Definition |
|---|---|
| 1. Polygon | A. A four-sided polygon. |
| 2. Triangle | B. A closed 2D shape made of straight lines. |
| 3. Quadrilateral | C. A polygon with five sides. |
| 4. Pentagon | D. A three-sided polygon. |
| 5. Hexagon | E. A polygon with six sides. |
Match the correct pairs:
Fill in the blanks with the correct words from the word bank below:
Word Bank: sides, straight, closed, angles, polygon
A ______ is a _______ shape that is made up of ________ line segments. It must be ________, meaning all the lines connect. Polygons also have ________ where the sides meet.
Answer:
A polygon is a shape that is made up of straight line segments. It must be closed, meaning all the lines connect. Polygons also have angles where the sides meet.
