Classwork:
- We started class by going through the homework from last night (the CRCT review sheet) and discussing/showing numerous ways to solve each problem. Hopefully you noticed there isn't always just one correct way to find the correct answer. I was impressed with how many of you thought of alternate ways to solve the problems.
- We talked about theoretical probability…the chance that an event should occur. For example, "What is the probability I will roll a number less than 3 on a normal die (singular for dice)?" We write the probability in fraction form…the denominator would be the number of possible outcomes, which would 6 because you can possibly roll 6 different numbers (1, 2, 3, 4, 5, or 6). The numerator would be the number of ways the event can occur…how many of those 6 possible outcomes would be less than 3? If you rolled a 1 or a 2 those are the only two ways you can roll a number less than 3, so there are 2 ways, so 2 is the numerator. The probability of rolling a number less than 3 = 2 / 6 (two ways you can roll a number less than 3/6 possible outcomes or 6 possible numbers you can roll). Remember to simplify, so 2/6 = 1/3. The probability of rolling a number less than three should (theoretically) occur once out of every three rolls.
- We worked through about 10 different problems together which included doing a few of your homework problems together to make sure you understood what to do.

Homework:
- Thin workbook – page 105
- Warm-up Quiz tomorrow…be sure you have the first nine completed, and you'll get warm-up #10 tomorrow before the quiz

Classwork: You took the Unit 7 test today – It addressed surface area, volume, and characteristics of solid figures
Homework: The CRCT Review Half Sheet (there are 10 problems on the sheet, but you do not have to do #9…we're going to learn about probability starting tomorrow
)

Classwork:
- We reviewed the homework/classwork before you took the volume quiz
- You took the volume quiz
- You received the study guide today, and you are to fill in the blanks for homework tonight….it looks like a lot of work, but it really isnt ~ it's just a few problems broken down step-by-step
Homework:
- Complete the study guide
- Study for Monday's Unit 7 Test
- Review session tomorrow morning at 8:15 A.M. – be in the theater by 8:15 and I'll come down and get you at that time

I uploaded the Unit 7 Study Guide in case you wanted to get a head start, but we will be going through the study guide together in class on Friday…whatever time remains after we complete the study we will play a review game (so if everyone is done early, then we'll have more time for the game
)

Classwork:
- You took your second timed drill of the week….one more try on Friday!
- We went through last night's homework
- You worked on a class assignment….you had approximately 30 minutes to complete it or to come up and get it checked to make sure you were on the right track. Some of you finished in class which is great because you were using your time!
Homework:
- Study for Volume quiz tomorrow
- Finish your class assignment…read below to see what problems your class was assigned
- 1st, 2nd, & 3rd period: Thin Wkbk-Page 89: 1, 2, 6, & 7; Thin Wkbk-Page 90:2, 4, 6, 7
- 4th period: Thin Wkbk – Page 89: 2 & 6; Thin Wkbk – Page 90: 2 & 4
- All classes were assigned the following two problems from the board
#9: An Egyptian pyramid has a rectangular base which is 75 feet long and 65 feet wide. The height of the pyramid is 120 feet. How many cubic feet would fit inside of the pyramid?
#10: A waffle cone is 22 cm tall and has a diameter of 24 cm. What volume of cookie dough ice cream will fit inside the cone?
- Unit 7 Test – Monday: You will be allowed to use the formula sheets and a calculator, but remember you will not have the opportunity for test corrections on this test. The first grade will be your final grade. There will be a review session Friday morning at 8:15…be in the theater if you would like to attend!

I forgot to upload this to my earlier blog today….just in case you need a few more examples of how to calculate the volume of a cylinder!

Classwork:
- You took your first timed drill of the week…we're going back to the same concept as last week, but this week you're given the decimals, and you need to write the percent and fraction (in simplest form) equivalents
- We reviewed how to find volume of rectangular prisms and rectangular pyramids by going through your homework and reviewing how the volume of a rect. pyramid is 1/3 the volume of a rect. prism with the same size base and height.
- We then saw how the volume of a cone is related to the volume of a cylinder with the same size base and height. Just like with the pyramid, the cone is 1/3 the volume of a cylinder; therefore we use the same formulas as we did yesterday!
- Volme of a cylinder: V = B x h (for cylinders the B – Area of the Base – is calculated using pi times radius squared)
- Volume of a cone: V = 1/3 x B x h (Area of the base of a cone is also a circle, so you will use pi times redius squared)
- We worked through one example from each side of your homework…be sure you set up the problems so we can see what you did step-by-step!
Homework:
- Common fractions and their decimals and percent equivalents timed drill tomorrow (and probably on Friday)
- Worksheet 12-7 & 12-8: Cylinders and Cones only tonight
- Volume Quiz – Thursday
- Unit 7 Test – Monday

Classwork:
- You received your surface area quiz back, and I was very impressed with the grades! Most of you really stepped up and put forth some good effort and did a great job showing your work step-by-step.
- We walked through an activity dealing with volume and discussed how the volume of a rectangular pyramid is 1/3 the volume of a rectangular prism….that's where the formula came from on your formula sheet.
- We did a practice volume of a pyramid problem (#14) on your class sheet.
- Bring the sheet with you tomorrow so we can go through the volume of a cylinder and a cone
Homework:
- Worksheet: Both sides, but you are only doing the volume of rectangular prisms and rectangular pyramids (side 12-7 complete #1, 6, 7, & 10 on side 12-8 complete #2, 4, 6, 7, & 8). You should continue to do your work on a separate sheet of paper with the formulas shown, numbers substituted in, and each step broken down….you did great with this on Friday's quiz, so keep up the organization of your math work.
- Volume quiz – Wednesday
- Timed Drill tomorrow (common fractions and their decimal and percent equivalents)
- Unit 7 Test – Monday, March 30

Classwork:
- You took the last timed drill of the week….we'll be working with those same common fractions, decimals, and percents again next week for timed drills, so be sure you study them again! If you have them memorized, then you're good to go
) Next week I might give you the decimal or the percent….I haven't decided as of yet.
- We talked about the surface area assignment from your thin workbook – page 91. We discussed any questions you might have had before taking the surface area quiz
- You took the surface area quiz
- You began working on the homework with any remaining time. Remember the homewok is only addressing the volume of rectangular prismsWe are not working with any other solids at this point. If you use the formula on your sheet V = B x h remember "B" means the area of the base, so you have to do "length x width" to find the area of the base, then multiply that answer times the height (so length x width x height)

- Download Volume of Rectangular Prisms
Homework:
- Common fractions and their decimal and percent equivalents timed drills next week
- Thick workbook – page 357: 1 – 6 & 10
- The unit 7 test will be in given in approximately one week
