Video+3

I. Before you watch the video answer the following questions. The title of the video is "Algebra I" What do you think this video will be about? I think that this video will be about topics belonging to algebra 1
 * Great job ! ! **[[image:christmas3.gif]]
 * Video 3: "Algebra I" **

Mention five words you think you might listen to in the video. Equation, plus, resolve, less, equal.

II. Now click on the following link and watch the video. While watching, please answer the following questions:

1. Mr. Mc Call is solving three types of equations in this video. Which are those types of equations? The first type of equation is with a variable in one side. The second type is with variables on both sides and the third type is a equation with multiple variables ( different variables )

the first type-- the second type --the third __typa__ type

2. What are the two keys he mentions for solving any equation?

The first key, is __the__ to add of the members, in others words, the sum of a number with its opposite, for example,. Opposite of 2 is -2 because 2 – 2 is equal to cero. The second key, is a reciprocal number (multiplying of numbers on both sides), for example, reciprocal of 3 is 1/3

3. a. Mention the steps he takes to solve the 1st problem. The first step was apply the first key that is add up on both sides 2 positive and later, he used the second key, that was, multiply one divide by five (-1/5) on both side. b. What kind of equation is this one? The first kind, that is to say, an equation with one variable on one member.

4. a. Mention the steps he takes to solve the 2nd problem. First step, Mr. Call solves the distributive property. Second step, he passes the variables on one side and combines it. Third, He used the first key, the add of member for sum negative 20 plus 2. Finally, applying the second key was divided by 5 on both sides and the result of the equation has been obtained b. What kind of equation is this one? It is an equation with variables on both sides. 5. a. Mention the steps he takes to solve the 3rd problem. First step was apply the add of members, for to leave alone the variable in one side, later, with de second key, it’s divided by two to get the result of the equation. b. What kind of equation is this one? It is an equation with multiple variables.

6. a. Mention the steps he takes to solve the 4th problem. The first step is multiplying the reciprocal numbers on both sides, with this, now is possible add up on both members with –c, and ready, the equations was solve. b. What kind of equation is this one? It is an equation with multiple variables. c. What’s the difference between problem 3 and problem 4? The difference is that in the 4th problem, it is used first the first key while in the third problem was used first the second key.

7. Did you like the video? Yes I like so much, because the algebra, for me, is very interesting, in addition, that I understood almost all the video. 8. What new things did you learn? Well, with this video I really know why I do what i when I solve an equation, because I do many equations without to know why.
