Today in class we learned how to find the surface area of a pyramid, and practiced these, and other, area problems. We will look at area of cylinders tomorrow.

Sorry that I missed yesterday's post! Yesterday students completed their benchmark and practiced fractions in a Ten Marks Jam Session. Today we practiced surface area of rectangular and triangular prisms.
Homework: Please go to Ten Marks tonight to complete the two sets of problems assigned. Be sure to use your notes and any hints the site offers. You may also pull up videos or other websites to help.In class today students took the 3rd quarter benchmark.
Homework: I have created two more Ten Marks assignments. Ten questions each, both are review and due by class start time on Friday. Some of the circle questions have you leave answers in terms of pi without multiplying by 3.14, or hitting the pi button on the calculator, - just like the EOG will. In class today students remembered what they know about 3 dimensional shapes: their names, faces, and area of the lateral surfaces. We also talked about what the units are for area (squared) and volume (cubed).
Homework: Complete the Exploring 3D Rectangular Prisms. Use your notes from today and any teacher you tube video that may help.Math 3rd quarter benchmark tomorrow Today in class students took a 2D Geometry test. Some will finish this during SMART Block on Monday.
Homework: noneIn class today, students used their class notes to help them find the area and perimeter of shapes. We traded,
reviewed the answers, and graded these problems. They will be returned tomorrow. Homework: TEST on Friday, please practice (Khan academy, Cool Math, Purple Math, you tube teacher videos, etc)In class today we continued to look at how the area of a figure changes when one or two dimensions are changed.
Homework: We will quiz tomorrow, using given formulas, on the area and perimeter of shapes. Test Friday will include area, perimeter and scale (changing the dimension of a figure). Answers for practice problems: Area of a Rectangle Rectilinear Area Area of a Triangle Area and Circumference of a Circle 1.16 1. 22 1. 85 in 1a. 380.13 1c. 69.12 2.72 2. 40 2. 142.5 mm 2a. 78.54 2c. 31.42 3. 30 3. 44 3. 110.5 mm 3a. 38.48 3c. 21.99 4. 32 4. 62 4. 9 km 4a. 660.52 4c. 91.11 5. 18 5. 26 5. 924 mm 5a. 706.86 5c. 94.25 6. 49 6. 55 6. 104.5 m 6a. 490.87 6c. 78.54 7. 35 7. 29 7. 3116 ft 7a. 615.75 7c. 87.96 8. 18 8. 45 8. 171 m 8a. 283.53 8c. 59.69 9. 12 9. 60 9. 78 km 9a. 346.36 9c. 65.97 10. 20 10. 52 10. 4050 ft 10a. 28.27 10c. 18.85 11. 40 12. 14 13. 18 14. 18 15. 16 In class today we looked at how changing one or two dimensions of a figure changes its area.
Homework: Practice area and perimeter for a quiz Wednesday. The test on Friday will also include the dimension changes.Try to complete the Measurement Assignment - area and perimeter of the swan. In class today we used our area formulas to solve a circle puzzle followed by a comparison of round vs. square pizza. We stepped back a little to also calculate the unit rate of price per inch of the pizza to truly determine the best value.
Homework: Complete the pizza comparison page from class.2D Geometry Test next Friday Answers to HW: 50 square inches and $0.20/inch 79 square inches and $0.27/inch 64 square inches and $0.14/inch 196 square inches and $0.08/inch 154 square inches and $0.10/inch 100 square inches and $0.20/inch In class today we reviewed the circumference of a circle and added notes about finding the area of a circle. We also practiced finding perimeter and area of different shapes.
Homework: Complete 'Circles' - on the back of the notes about circles. |
