  1. 21st Century Lessons Review Area Lesson Mrs.Thompson

  2. Lesson Overview (1 of 3)

  3. Lesson Overview (2 of 3)

  4. Lesson Overview (3 of 3)

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

  6. Agenda: OBJECTIVE: SWBAT select the correct dimensions and calculate the area of diagrams and real-world problems. 1) Warm Up 2) Getting Ready – Reviewing Trapezoids 3) Partner Work – “Study This” Cards 4) Mini- Lesson 5) Practice – Identify Formula and Base & Height 6) Practice – Interleaving 7) Practice – Calculating Area 7

  7. Getting Ready How can BOTH formulas be correct? Agenda

  8. Mini-Lesson: Identify the base and height What is true about the bases and heights of all the shapes we have studied so far? height height height height base base base base Agenda 13

  9. Mini-Lesson: Identify the base and height The height is always perpendicular to the base. height base Parallelogram Agenda 14

  10. Mini-Lesson: Identify the base and height The height is always perpendicular to the base. height base Right Triangle Agenda 15

  11. Mini-Lesson: Identify the base and height The height is always perpendicular to the base. height height base base Non-Right Triangles Agenda 16

  12. Mini-Lesson: Identify the base and height The height is always perpendicular to the base. base 2 height base 2 base 1 height base 1 Trapezoids Agenda 17

  13. Interleaving Practice Name the formula you would use to calculate the area of each shape. Then, identify the bases and heights in these next shapes! Agenda 18

  14. Practice – Interleaving: My Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 7 cm 1) 3 cm 2 cm h = 2 cm 3cm b = 7 cm 7 cm Agenda 19

  15. Practice – Interleaving: Your Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 6 ft 2) 4 ft h = 3 ft 3 ft 4 ft b = 6 ft 6 ft Agenda 20

  16. Practice – Interleaving: My Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 3) 10 m 15 m h = 7 m 7 m b = 15 m 15 m 10 m Agenda 21

  17. Practice – Interleaving: Your Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 4) 4 cm 9 cm h = 3 cm 3 cm b = 9 cm 9 cm 4 cm Agenda 22

  18. Practice – Interleaving Name the Formula you would use to find the Area Record the base and height needed to find the area. 5) 5 in h = 4 in 4 in b = 3 in 3 in Agenda 23

  19. Practice – Interleaving Name the Formula you would use to find the Area Record the base and height needed to find the area. 6) 13 in 5 in h = 5 in b = 12 in 12 in Agenda 24

  20. Practice – Interleaving: My Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 7) 6 mm 4 mm h = 3 mm 3 mm b = 7 mm 7 mm Agenda 25

  21. Practice – Interleaving: Your Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 8) 13 yd 5 yd h = 4 yd 4 yd b = 17 yd 17 yd Agenda 26

  22. Practice – Interleaving: My Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 9) base 2 = 8 ft 8 ft 6 ft h = 6 ft 7 ft 7 ft base 1 = 6 ft 6 ft Agenda 27

  23. Practice – Interleaving: Your Turn Name the Formula you would use to find the Area Record the base and height needed to find the area. 10) base 2 = 74 ft 74 ft 62 ft h = 48 ft 48 ft 62 ft 100 ft base 1 = 100 ft Agenda 28

  24. Interleaving Practice Now that you have all of the information you need, Calculate the Areas! Agenda 29
