Today, in Algebra, we took a quiz on solving equations and word problems. Student did pretty well. The parent portal is updated with their grades, if you would like to see! After the quiz, students worked on solving decimal equations. For homework, students must complete Page 169 #21-39 odd. Remember, you can check the answers in the back of the book, just make sure you show all your work! You can use a calculator, but again if no work is shown, you will not receive credit!
In Pre-Algebra, we discussed similar figures and determined the rules for similarity. We started a sorting activity in class, where students cut out figures, and then place them into categories, either "similar" or "not similar". Also, student must explain their reasoning. For homework, they have to finish their sorting activity from class.
Pre-Algebra has a test on Friday on transformations, including rotations, reflections, translations, and dilations, as well as similar figures. They must know all of the transformation rules (there are 4 that they must know) because the rules will not be given to them on the test. The rules that the students must know are:
Rotations 180 in either direction: (x, y) --> (-x, -y)
Rotation 90 degrees clockwise/270 counter-clockwise: (x, y) --> (y, -x)
Rotation 90 degrees counterclockwise/ 270 clockwise: (x, y) --> (-y, x)
Reflection across y = x: (x, y) --> (y, x)
I suggest that the students make flash cards to help them study, or to use the Quizlet account that Mr. Costa has set up for them. I was after school for review today, but I am also available tomorrow and Thursday until 3pm. I really hope I see students staying after school to get the help that they need. This test is one of the more challenging ones of the year, and I really want the students to do well! Plan on staying! :)
