HW: Page 86 19 - 28 AND
We started with a 6 questions review of 2.4. Students worked on their own and then we checked them in class. Students also received their Quiz 1.6 back. We discussed some common errors. Then we talked about 2 other forms of an equation of a line: point-slope form and standard form (Ax + By = C). We mentioned that standard form has only integer values for A, B, and C, and it is very easy to find x and y-intercepts. We completed about 7 questions using point-slope form.

Due to 1/3 of the class being gone on a fieldtrip, the remaining students had an work day on their book assignment from 2.4.
HW: Complete book 2.4 assignment page 86 - 88 9, 10, 13 - 15, 32, - 34, 42 - 44, 48, 57, 58 We went through how to write the equation of a line given a point and a slope or given 2 points. This is a very important skill. We went through 4 examples and showed how to check our lines by graphing them on the a graphing calculator and tracing on the 2 x-coordinates. We also saw reviewed how to write the equation of a line that is either parallel or perpendicular to a given line through a point.
HW: None. If you are in class tomorrow (freshmen on a fieldtrip - have fun) bring your books an d be ready to work in class. We did a quick lesson check on 2.3 with 6 review questions. We answered all of them in class. We also went over the book assignment 2.3 and answered question #56. This was collected. Then students had the last 25 minutes to complete the 1.6 quiz. We used the last 4 minutes of class to play Near Miss.
HW: NONE if you are all caught up on your work We completed the 5 question warm-up on section 2.2 and went over the solutions. We went over question #13 on WS 2.2 and it was collected.
We quickly reviewed slope-intercept form of a line. We were able to write the equation of a line given a slope and y-intercept (or read it from a graph). We could transform a linear equation into slope-intercept form and graph it. We also reviewed how to find the slope between 2 points. HW : Page 78 - 80 14 - 18, 24 - 27, 30, 32, 44, 47 - 52, 56 - 58, 63 - 65 Quiz on 1.6 is tomorrow (9/10) Students did a quick warm-up check on section 2.1 (5 questions). We went over these and the even problems from book 2.1. We also went over #28 and then collected book 2.1. Next we collected class data on student's height (in cm) and the corresponding kneeling height. We recorded the data in Excel and used it to calculate the ratio of standing height to kneeling height. We found that the ratio was about 1.3.
Then we quickly went over that a direct variation is a linear equation that goes through the origin and is in the form y = kx. k is called the constant of variation. We went through 3 equations to determine if they were direct variations. Use the links below for more information on direct variation. https://www.youtube.com/watch?v=nZOlvKCrfNg https://www.youtube.com/watch?v=-uQbvcHEfWY https://www.khanacademy.org/math/algebra/algebra-functions/direct_inverse_variation/v/direct-variation-1 HW: WS 2.2 both We started by having students write to a person who needed help in solving an absolute value equation. We shared our tips with our table and then proceeded to demonstrate how to solve the absolute value equation given. We discussed our tips and then worked out the problem together.
Students exchanged projects and examined each other's work (mathematical practice #3: critique the reasoning of others) and then discussed any questions. The Buy the Hour Project was turned in today. The quizzes and 1.6 homework was returned and we went over some common errors in 1.6. Lastly, we played the game Hit or Miss. The book review from page 53 with the Literal Equations WS (evens or odds only). I will collect the 2.1 book assignment (given earlier in the week) on Monday. There was no additional homework today. :) Today we were in the computer lab for students to complete their Star Math testing.
Students used extra time to complete their Buy the Hour projects. HW: Buy the Hour project is to be turned in tomorrow, Sep We completed 3 review questions in class and had 3 groups present.
Students had the last 20 minutes to work on activity 3 and 4 in the project. Book assignments 1..4, 1.5 and 1.6 have been collected. HW: activity 3 and 4 in the project, project is due this Friday. Tomorrow go to D12C. Today we started discussing 3 big topics: function notation, domain & range, and the vertical line test (VLT). We went through mappings, charts, graphs, and ordered pairs in identifying a function. We used the example of a person's weight on a scale being an example of a function. A function has only one output for each input (or in other words a person cannot pick their weight from various outputs on the scale).
HW: Buy the Hour project should have activity 1 & 2 completed. Page 65 - 66 20 - 25 |
