12/8 Algebra 2

Today we learned the final method for solving a quadratic equation, the quadratic formula. I derived the formula for the students on the board, then showed them how to use it to solve an equation. See some more examples here. Students practiced using the quadratic formula on a worksheet, then did a short graded assignment. They will also be doing a review worksheet for homework, as we will be having a quiz over Chapter 5 on Tuesday.

Homework:
page 295 #'s 17-40 every 3rd problem & Chapter 5 Review Worksheet

12/7 Pre Algebra

Today we will be working with percents. We will be changing percents to decimals and finding percents of certain numbers. We will review Tuesday's lesson since I was absent, then do a worksheet in class together on the percents.

Homework:
page 346 #'s 4-15 & pages 352-353 #'s 1-8, 25-30

12/7 Applied Geometry

We will wrap up Chapter 6 today, moving away from parallelograms, but still studying quadrilaterals. Today's types of quadrilaterals are trapezoids & kites. Students began class by filling ot a sheet that contianed definitions and properties of our 2 figures. We then went through a chart of all our figures studied in Chapter 6, listing the properties for all. We did some worksheets together in class solving for parts of trapezoids & kites, then students worked onthe graded assignment.

Homework:
pages 433-434
14-18, 20-25, 27-36

Last Extra Credit Chance for Algebra 1

Final opportunity for 2nd quarter Extra Credit:

To get credit, you must submit your answer before the end of the week, then show me your name on the list of people who go it correct. This probelm will only be posted until Friday.

12/6 Algebra 1

Today we will be reviewing for the Chapter 5 Test. Students will be working on the Chapter 5 Review Packet. The Chapter 5 Test will be Friday.

12/6 Algebra 2

Today we learned yet another method for solving a quadratic equation, called completing the square. This method involves changing the form of the equation by adding something to both sides, so we are able to take the square root of both sides to solve, as we did on Monday. This is the next to last method we will investigate for solving quadratic equations. After doing some examples on the board, students will practice on this worksheet, then the homework. See some examples of completing the square here.

12/5 Pre Algebra

I will be gone this afternoon, but the substitute has the following plans for the class.

1) Students will do p. 355 #'2 1-16 at the beginning of class, which will be taken for a grade.
2) Students will do the following worksheet in class, practicing multiplying and dividing fractions. The class will go over the worksheet together.
3) Students will work on a graded assignment, page 326 #'s 10-21 & page 332 #'s 11-37, this will be due in class today, and graded if there is enough time.
4) The 7.6 worksheet will be due on Thursday, it deals with changing fractions to percents.

Homework:
7.6 worksheet (can be viewed from above link)

12/5 Apllied Geomtry

We will continue our study of parallelograms today, focusing on special parallelograms: rectangle, rhombus & square. Students will use the properties of these special parallelograms to find side lengths and angle measures. They will also show that a particular parallelogram is one of these by showing that one of the properties is true. We did some worksheets together in class, then students worked on the graded assignment.

Homework:
p. 402 9-14, 20-23 & p. 412 14, 18-31, 40-42

12/4 Algebra 1

Today we will be finishing our work from the previous lesson and continuing on to a new lesson. The new lesson has students writing linear equations in standard form, shown above. Writing an equation in standard form requires having the x and y on the smaeside of the equal sign, with whole number coefficients.

Homework:
page 311 24-42 even

12/4 Algebra 2

Today we worked on simplifying the square roots that are solutions to our quadratic equations. For example the square root of 18 can be simplified to be 3 times the square root of. 2. We will also be simplifying fractions that have square roots as the denominator.

Homework:
pages 267 - 268 #'s 20-68 even

Algebra 2 2nd Quarter Extra Credit:
Last chance for extra credit before the semester is over. Use the following equation for the height of the water to solve the following problem.

For a bathtub with a rectangular base, the height of the water in the tub h, t seconds after it begins draining is given above. Suppose you fill a tub completely full, the tub is 72 inches long by 28 inches wide by 28 inches high. The drain has a 2 inch diameter. a) Find the time it takes for the tub to go from full to half-full. b) Find the time it takes for the tub to go from half-full to completely empty.
