Day 120: Topic Seven Assessment

Students in all classes completed their Topic Seven Assessment.

Today's Lesson Objective(s):

• Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes.
• Apply these techniques in the context of solving real-world and mathematical problems.
• Find the volume of a right rectangular prism with fractional edge lengths by packing it with unit cubes of the appropriate unit fraction edge lengths, and show that the volume is the same as would be found by multiplying the edge lengths of the prism. 
• Apply the formulas V = l w h and V = b h to find volumes of right rectangular prisms with fractional edge lengths in the context of solving real-world and mathematical problems.
• Represent three-dimensional figures using nets made up of rectangles and triangles, and use the nets to find the surface area of these figures. 
• Apply these techniques in the context of solving real-world and mathematical problems.
• 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.
