Attributes of Polygons--exploration
If you like playing with shapes and building things then you will love geometry! Let's start with some basics by reviewing some shapes and their properties! Let's check out StudyJams!
Next: QUADRILATERALS: http://studyjams.scholastic.com/studyjams/jams/math/geometry/classify-quadrilaterals.htm
Then let's check out TRIANGLES! http://studyjams.scholastic.com/studyjams/jams/math/geometry/classify-triangles.htm
Now you are going to create some polygons using the Geoboard App.
Make three TRIANGLES. Can you you label them? Where are the sides? How many angles are there? Take a screen shot of your Geoboard work!
Next, create three QUADRILATERALS! Can you you label them? Where are the sides? How many angles are there? Take a screen shot of your Geoboard work!
Now it is time to show what you have discovered!
Using your Skitch App, create a mini poster with your Triangle Screen Shot. How many different properties can you label? For example: label a line, a segment, an angle.
Next, create a mini poster using your Quadrilaterals Screen Shot. How many different properties can you label? For example: label a line, a segment, an angle.
Feel free to go back to StudyJams, or use a math reference book to help you label your pictures! Be creative!
Key Standards Supported
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
