8th and 9th grade assignment for the week of 5/4/20
Hi to all 8th and 9th graders!
Below, please find a link to a decent enough online calculator. As always, the older assignments will appear further down on the page.

If there is one topic that is just as important to Algebra 1 as it is to 8th grade, it is the subject of linear equations. Both grade levels are required to know how to write an equation, make a table, and graph linear functions in two variables. You need to know what slope (aka, rate of change) and the y intercept (aka, initial value) are and how to use them. In the following exercise, you will be required to write an equation from a table or graph, graph a line given an equation or table, or write and graph a line from data recorded in a table. Basically, then, this is a combined linear equation review.
So, let’s start with the parts of a linear equation. Please go to the link below.

Next, let’s do a quick review on how to calculate slope from a table, a graph, or two points.

8th & 9th grade assignment for the week of 4/28/20.
Hello 8th and 9th Graders
Below, please find a link to a decent enough online calculator. As always, the older assignments will appear further down on the page.
https://www.calculator.net/scientific-calculator.html
This week, we are going to work on geometric concepts that are common to 8th and 9th grade. You will be finding the area and volume of common shapes, but you may not remember how to do them all. Actually, this is good news, because I want you to practice on using your search skills to teach yourself a topic.
This assignment will have you answer math questions that are based on the movie Tangled, so, if you have a copy or you can pull it up online, watch it. It’s funny! If you don’t have access to it, you will just have to answer the questions without the fun of watching a movie. Use the context clues within the descriptions to find what topic you need to search. For instance, if a question states that the roof of a castle has the shape of a square pyramid and they want to know the volume, search for how to find the volume of a square pyramid. I assure you, you will find dozens of resources and tutorials.
As always, please do check with me if you have questions, but see how much of this you can find on your own. This is useful math and you are up to the challenge!
Good luck! The assignment is attached or the link is found below.

Algebra 1, week of 4/20/20 links and assignment
Last week, we took a glance at what quadratic equations look like. Quadratic equations are characterized by parabolic shapes that either open up or down. What true quadratic equations have in common is that they will cross the X axis at two points. These points are the “zeroes” of the function and are also considered the solution. Going back a couple of weeks, we were practicing factoring of trinomial expressions into binomial pairs. I know, big words, sounds complicated, so here is an example:
X^2 + 5X + 6 = (X + 2)(X + 3)
Remember that? So, imagine that what I am looking for are the values of X that will result in a Y value of zero. In the first factor, -2 + 2 = 0. Therefore, the graph of the trinomial above will cross the X axis when X is -2. On the other side, -3 + 3 = 0, which mean the parabola will also cross the X axis when X is -3. To see this, please follow the link below and in the spots for a, b, and c, put in 1, 5, and 6. It will show you the parabola that is formed.
https://www.mathsisfun.com/quadratic-equation-solver.html
You should see that the parabola does, in fact, cross the X axis at -2 and -3. It is also important to note that the standard formula for a quadratic equation follows the pattern
ax^2 + bx + c = 0 , wherein a, b, and c are coefficients and constants. Factoring is one way to find the zeroes of the graph, but it can become complicated when the coefficients are not nice, whole numbers. The other way to find the zeroes is to use the quadratic formula. The formula is what we will be concentrating on this week. To find an image of it, simply do a google search on quadratic formula. For examples of how this is used, take a look at the following link:
https://www.mesacc.edu/~scotz47781/mat120/notes/quad_formula/quad_formula.html
For additional help on how to use the quadratic formula, please follow the links below:

Finally, the assignment is either attached or can be found by following the link below. There aren't many problems, only 8, but the real answer is in the work, so please show it.

Algebra 1 assignment week of 4/13/20
Hello to all. Just a quick reminder that the newest assignments will be near the top of this page and the older assignments are below. Some of the oldest assignments will have been deleted.
This week we are going to begin looking at quadratic functions. The practice that we have been doing on multiplying and factoring polynomials was in preparation for this. First up, let's take you to some notes to help you understand quadratics. The site that I have selected will provide good notes on the topic and it has an extra bonus. At the bottom of the page, you will see a link to a quadratic solver. At some point, you should play with that.
https://www.mathsisfun.com/algebra/quadratic-equation.html
The bulk of your assignment will be from a textbook, which I have copied and will make a link available below. If you are collecting packets from the office, the textbook pages will be attached. Please read the text of the chapter and then do problems 1 through 37 on pages 549 through 551. I have included a link to an online graphing calculator that will help you see the graphs of quadratics and it is given below:
