F Block Algebra 2 (Day 1) Thurs., Feb. 28 — Dividing Polynomials — Long Division

Today: We took it easy and only covered long division of polynomials.  Watching the signs is the most important and most challenging thing about this process.  Take it one step at a time.

Homework: p.  324/1-11 odd.

Next Class: We will divide polynomials again using synthetic division — a cool process.  Fun times!

I Block Algebra 1 (Day 1) Thurs., Feb. 28 — Adding Exponents when the Bases are the Same

Today: That’s what we talked about.  You add the exponents when the bases are the same.  You did several examples in class and asked good questions again.  Keep taking it one step at a time!

Homework: p.  443/ 3-21 (the 3rd column)

Next Class: We will see how you can use the rule we learned and move on to the next one.  We will also have a graphic organizer that will help you keep all the information you are learning about exponents organized.

D Block Algebra 1B (Day 1) Thurs., Feb. 28 — Factoring Special Cases

Today: We talked about the special cases of perfect squares and differences of squares.  I let you know that you will not be tested on whether you memorize the pattern or not, but that it will help you move quicker through problems.  We went through what the text book says, because no one ever really reads the text.  This is  a shame, because they can be so helpful if you know how to read them!  You all had good questions about vocabulary and processes, but my favorite was Min Jin’s that led to the Quadratic Formula — a taste of what is to come!  Good work today, you guys!

Homework: Part 1: Do Quick Checks 1 and 2 on page 529 and check your answers in the Instant Check System in the back.  If you get them right, you may choose to skip part 2.  (You can do part 2 if you would like more practice anyway.)  If you get them wrong, do Pat 2 for extra practice.

Part 2: p. 531/ 12-36 (odd multiples of 3).  Check your answers in the back of the book.

Part 3: p. 532/ 57-63 odd.

Next Class: We will learn more way to factor things.  This one will be easy compared to the others.

A Block Geometry (Day 1) Thurs., Feb. 28 — Area Review

Today: We spent the class answering very good questions about the are worksheets you were supposed to do yesterday and last night.  I’m glad we spent the time, because the book’s answers were wrong.  We also established the idea that to find the area of the shaded region, you find the area of the larger figure and subtract the area of the smaller.

Homework: Look back over the mistakes you made and make sure you understand all of the problems between these three pages.

Next Class: We will be moving on to even more challenging problems and ideas with area, so it is important you understand the ones here.

D Block Algebra 1B (Day 6) Wed., Feb. 27 — Quiz and More Factoring (Special Cases)

Today: You took a quiz on factoring so far.  Then, you took notes on questions you have about the special cases.  You also had the time to practice online.  Make sure you log in.

Homework: Complete the tasks from above that you did not complete in class.

Next Class: We will move forward with the special cases of factoring and then move into solving equations.

A Block Geometry (Day 6) Wed., Feb. 27 — Are Review

Today: You will do worksheets that review the area formulas we have discussed so far.  You may use your textbook.

Homework: Finish the worksheets.

Next Class: We will discuss how the area formulas for rhombuses and polygons relate to base times height.

H Block Geometry (Day 6) Wed., Feb. 27 — Area review

Today: You worked on sheets that used all of the formulas you have learned so far (minus rhombuses and polygons).

Homework: Complete the worksheets if you did not in class.

Next Class: We will complete the formula posters with circles.

B Block Algebra 1 (Day 6) Wed., Feb. 27 — Word Problems and Stabdard Form

Today: We worked on reviewing standard form.  You answered application problems with linear functions.  There were some good conversations going on.  It takes time to learn how to ask questions of people you don’t know or just met.  We will continue working in those groups.  You also received a review assignment that is listed below.

Homework: p. 365/ 6-24 (multiples of 3), 19.

Next Class: We will discuss the assessment plan for the past few chapters, and we will move forward to finish chapter 6 with point-slope form.

H Block Geometry (Day 5) Tues., Feb. 26 — Area of Rhombuses and Polygons

Today: You worked on your posters after receiving a mini-lesson on the area of rhombuses.  They both have a similar idea of breaking the shape into pieces.  It’s similar to a circle, so that’s why I referred you to page 451 to figure it out.

Homework: You have none.

Next Class: You will review the formulas you have worked with so far.

B Block Algbera 1 (Day 5) Tues., Feb. 26 — Stadard Form of a Linear Equation

Today: We talked about how to find the intercepts from an equation and how to use the intercepts to graph a line.  We then talked about how to graph horizontal and vertical lines.  After that, we talked about how to get an equation into standard form using the rules of equations.  Finally, we looked at a word problem, so we could see that the intercepts have meaning within the real-life situations.

Homework: p. 333/5-9 odd, 10-14, 19, 23, 29, 30, 36.

Next Class: You will review what you have learned so far.
