21 st Century Lessons Review Area Lesson Mrs.Thompson 1

Warm Up OBJECTIVE: SWBAT select the correct dimensions and calculate the area of diagrams and real-world problems. Agenda 2 2) Find the area of the trapezoid 1) Why is the shape to the right a trapezoid? 5 yds 8 yds 2 yds 6 yds Formula It is a quadrilateral with 1 pair of parallel sides.

Warm Up OBJECTIVE: SWBAT select the correct dimensions and calculate the area of diagrams and real-world problems. Agenda 3 2) Find the area of the trapezoid 1) Why is the shape to the right a trapezoid? 5 yds 8 yds 2 yds 6 yds Formula It is a quadrilateral with 1 pair of parallel sides.

Mini-Lesson: Identify the base and height Agenda 4 What is true about the bases and heights of all the shapes we have studied so far? base height base height base height base height

Mini-Lesson: Identify the base and height Agenda 5 Parallelogram The height is always perpendicular to the base. base height

Mini-Lesson: Identify the base and height Agenda 6 The height is always perpendicular to the base. Right Triangle base height

Mini-Lesson: Identify the base and height Agenda 7 The height is always perpendicular to the base. Non-Right Triangles base height base height

Mini-Lesson: Identify the base and height Agenda 8 The height is always perpendicular to the base. Trapezoids base 1 height base 2 base 1 height base 2

Interleaving Practice Agenda 9 Then, identify the bases and heights in these next shapes! Name the formula you would use to calculate the area of each shape.
