Area_of_trapezoids_composite_figures
Finding the area of more complex shapes like trapezoids and composite figures (shapes built from other shapes)
Understand the formula for the area of a triangle.
Have you ever wondered how much fencing you need to surround a plot of land? No? Well, you should still go through this tutorial just in case. You'll learn what perimeter is and how to calculate it.
Transition from counting unit squares to multiplying side length to find area. Measure side lengths with a ruler to find area. Find area of rectangles by multiplying side lengths. Find a missing side length of a rectangle when given the other side length and area.
Area_and_circumference_of_circles
A circle is at the foundation of geometry, and at the foundation of a circle is a special number called Pi. This number allows us to relate the radius, diameter, and circumference of a circle.
Count_unit_squares_to_find_area
Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area. Create rectangles with a given area by covering unit squares.
Area problems involving triangles and quadrilaterals on grids
Understand the formula for the area of a parallelogram.
Learn about, prove, and apply area properties of specific types of triangles.
