Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
Grade: 09, 10, 11, 12
Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.
So, you want to know about circles, eh? Well, it’s a little trickier than measuring your average square. Luckily for you, Tim and Moby make circles and their measurement a cinch in this BrainPOP movie! First, you’ll learn what a circle is, how to find the center of a circle, and how to find and use a circle’s radius and diameter. Then, you’ll learn about handy formulas to use in figuring out a circle’s circumference and area. Plus, you’ll get introduced to the circle’s friend, pi, and you’ll discover how it’s used. Watch this movie and you’ll be flying through your geometry class in no time!
In this lesson plan, which is adaptable for grades 6-8, students use BrainPOP resources to explore basic geometry concepts related to circles, polygons, and triangles. Students then apply geometry understandings to real-life situations and virtual ones through online game play. This lesson plan is aligned to Common Core State Standards. See more »
