1 Monday, February 26, 2018 The lesson f: First, you will turn in your Geometry booklet. The teacher will review an example problem for you for how to do SA (next page). Then you will retake the quizziz NB55 and turn it in. Dear Students, Each class is competing to see which is best behaved and hardest working. A special treat will go to the winning cla If no class wins then... :( There will be another quick lesson and you will do a quick activity sheet. NB 56. Easy peasy. You will grade your own in class and keep it. Lastly, you will continue to work on SA NB54 and turn it in. If you do not finish NB54, it is hw to be turned in on Tuesday. This is a reminder of how to find SA. 5ft 4ft 3ft 10ft

3 Surface Area The sum of the areas of each face on a 3 D figure To find surface area, add the area of each face together Front 2 X 5 = 10 Back 2 X 5 = 10 Top 2 X 3 = 6 Bottom 2 X 3 = 6 Left 3 X 5 = 15 Right 3 X 15 = 15 5 Sum= 62 square units 2 Area The square units of measure inside an object unit2

4 Volume The amount of space an object occupies measured in cubic units Volume= area of the base area X height V= 6 X 3 X 4 V= 72 cubic units aka V = 72 units 3 unit Perimeter The distance around an object or polygon To find perimeter add all the sides together P= P=34 units

5 Perimeter, Area, SA or Volume? NB 56 Directions Determine if each situation is Perimeter, Area, SA, or V. If it is Perimeter, write P. Area A Surface Area SA or Volume V Write the abbreviation beside each number. Perimeter, Area, Surface Area or Volume? 1. wrapping paper on a gift box 2. Label on a can of food 4. how much rice will fill a bowl. NB SA 2. SA 3. A 4. V 5. SA 6. A 3. how much paper to cover the bulletin board 5. how much paint is needed to paint the walls of room 6. how many tiles to cover the bathroom floor 1. SA 2. SA 3. A 4. V 5. SA 6. A

6 Perimeter, Area, Surface Area or Volume? 7. Fencing around a garden 8. the amount of toys that will fit in a toy box. 9. how much cardboard to make a box 10. how much fabric to make a pillow 7. P 8. V 9. SA 10. SA 11. P 11. how much wood to make a picture frame. 12. how many stuffing to fill a pillow. 12. V 7. P 8. V 9. SA 10. SA 11. P 12. V Perimeter, Area, Surface Area or Volume? Answers NB SA 2. SA 3. A 4. V 5. SA 6. A 7. P 8. V 9. SA 10. SA 11. P 12. V

7 Tuesday, February 27, 2018 The lesson: First, you will turn in your Geometry booklet if you did not already (it's late) There is a POD which will help you with the next quizizz. Then you will retake the quizziz NB60and turn it in. Dear Students, It is still on, you might win. Each class is competing to see which is best behaved and hardest working. A special treat will go to the winning class If no class wins then... :( Next, work on NB 59, Volume Practice. Easy peasy. You will grade some of the questions in class, then turn in the rest. Lastly, you will continue to work on SA or V? NB59 and turn it in. If you do not finish NB59, it is hw to be turned in on Tuesday.

21 1. Find the area of the circle. Use 3.14 for pi. 2. Find the circumference of the circle. Use 3.14 for pi. 6.4 cm 8 ft

22 Explain how your would calculate the area of the shaded region. A outside = bh rectangle A = (6)(3) A = 18 cm 2 A inside = bh rectangle A = (5)(2) A = 10 cm 2 I would find the area of the unshaded region and then I would find the area of the shaded region with the unshaded region included. Lastly, I would subtract the unshaded region from the above total to find the unshaded region. The area of the shaded region is 8 cm 2 Find the area of the shaded region. Use 3.14 for pi.
