Math 2A: What is the slope of a line that passes through specific points?

Math 2A:  

Review graphing linear equations in standard form and after solving for y. Plot two points and draw a line; then find the slope of the line using arrows and reducing the fraction.

1.  Quiz on Thursday! 

Math 2A: How can we graph linear equations?

Math 2A:  

What is slope? What does a line with positive, negative, zero, or undefined slope look like? Graph linear equations in standard form by identifying the y-intercept (b) and the slope (m). The b-value tells you where to "begin on the y-axis," and the m-value tells you "how to move." Use arrows to decide whether positive or negative numbers are used.

Math 2A: More Practice with Graphing Quadratics

Math 2A:  

Complete selected Regents type questions on graphing quadratic equations. What are some test taking strategies to find the vertex and axis of symmetry of quadratic equations? Treat this like an open-book quiz!

Math 2A: How can we graph quadratics?

Math 2A:  

Good job on your quiz! Let's graph a quadratic and determine other interesting parts of a parabola besides the roots (or x-intercepts). For example what is the lowest or highest point of a parabola (vertex) and the line (axis) of symmetry? What does changing the coefficients of a quadratic do to the graph?  Make sure you copy the table and show all work!

Math 2A: How do we solve quadratic equations with factoring?

Math 2A:  

Let's use your factoring skills to solve quadratic equations. Since we cannot use strategies like the Distributive Property, combining like-terms, or inverse operations, let's use factoring and the zero property to solve equations. Why are there two solutions? What do our algebraic solutions represent graphically?

Math 2A: How can we factor expressions completely?

Math 2A:  

Use a graphic organizer to factor expressions completely. After you take out the GCF, figure out if the expression in the parentheses is a binomial or trinomial. If it is a binomial, Ms. Maida will help you; if it is a trinomial, I will help you. Then you will have a chance to be the binomial or trinomial.

Math 2A: More Practice with Factoring Expressions

Math 2A:  

In group of 4 or 5 rotate to each station to work with each teacher on factoring problems. In Station A, you will practice how to factor with a GCF; Station B, practice how to factor trinomials (a = 1) & binomials (DOTS); and Station C, factor completely using the GCF and one other method (This is new, so I will help you at this station). Have fun and ask questions at each station.

Math 2A: More Practice with Factoring Expressions

Math 2A:  

Let's work together to try to solve a matching puzzle for factoring. Each square has four sides with polynomial expressions or factored expressions. Match the sides that have equivalent forms and solve the puzzle! There is only one answer.

Math 2A: How can we factor a trinomial (where a = 1)?

Math 2A:  

Good work with the graphic organizer! You should always start in the first box and ask yourself, "Is there a GCF?" and factor that if possible. Today we will also check whether it is a factorable trinomial... Use one of the methods learned in class (ex: diamond puzzle or two column checking) to factor the trinomial expression.

2. Quiz on Friday.
   

Math 2A: How can we factor the difference of two squares (DOTS)?

Math 2A:  

What are perfect squares and how many do you know? What does it mean to take the square root of a number? Let's use a graphic organizer to factor expressions. This will help us find the quickest path to factoring an expression!

Math 2A: More Practice with Factoring the GCF

Math 2A:  

Let's practice factoring expressions with the GCF. It is very important that you always look for a GCF between the terms in a polynomial expression first! Then divide by the GCF to find the other factor of an expression. Complete problems around the room about factoring with a GCF.

1. Assignment: None.

Math 2A: How can we factor the GCF of an expression?

Math 2A:  

What are the factors of two or more monomials? Why should we take the greatest common factor out when we factor an expression? We do this by dividing the expression by the GCF. Does factoring mean we are solving for x? (No.)

Math 2A: How can we practice multiplying & adding integers?

Math 2A:  

Multiply and add integers without the use of a calculator--this will help you when we start factoring! Let's use these skills to solve diamond puzzles. Can you think of two numbers that have the product of the top number and the sum of the bottom number? 

Example:

Math 2A: How can we solve linear equations & inequalities?

Math 2A:  

Let's review for your test! Complete problems about solving linear equations and inequalities. You will have to complete some word problems on the test, so practice translating verbal statements into equations or inequalities

1. Assignment: Finish Review Worksheet

Math 2A: How can we solve linear inequalities?

Math 2A:  

How can we solve word problems with inequalities? Read the word problems based on The Lord of the Flies (Did you do your reading in English class?); then highlight key phrases and translate the inequalities. Solve the linear inequalities.

Math 2A: How can we solve linear inequalities?

Math 2A:  

How can we solve linear inequalities like we solve linear equations? These are a bit harder and you may need to combine like-terms or use the Distributive Property before solving. You should still test 0 to determine whether you shade to the left or right.

Math 2A: How can we solve linear inequalities?

Math 2A:  

How can we solve linear inequalities like we solve linear equations? Temporarily change an inequality symbol (ex: >) into an equal sign. Graph your solution on a number line, using an open or closed circle. Then test 0 in the original inequality. This will determine whether you shade to the right or left.

Math 2A: How can we translate linear inequalities?

Math 2A:  

Let's compare & contrast equations & inequalities... How are they different than expressions? What symbols do we use to represent verbal phrases, such as, "is greater than," "is at most," is no more than," "maximum," etc.
