Monday 8/29 - Review for quiz. Quiz on Literal equations, solving multi step equations and algebraic properties. Review graphing an equation in slope intercept form. Tuesday 8/30 - Solving systems by graphing. Wednesday 8/31 - Solving systems by elimination. Thursday 9/1 - Solving systems by elimination. I-respond. Friday 9/2 - Quiz: solving systems of equations. Write and solve word problems for systems of equations. Monday 8/29 - Below are the notes and classwork/homework. Today we started our "Interactive Notebooks". Please be sure you bring this to class every day as we will be updating it and referring to it on a regular basis. Maintaining your INB is part of your classwork grade.
We also started geometric constructions. Both classes copied a line segment. 1st block also bisected a line segment. Please review the contructions on the website: www.mathopenref.com and then look under constructions (copy a line segment, perpendicular bisector of a line segment). The website gives you the step by step instructions on how to perform all of the constructions we will cover. Today we started Unit 2 - Reasoning with Linear Equations and Inequalities. First we reviewed the order of operations (PEMDAS). Then we solved 1-step and 2-step equations applying our inverse operations. addition and subtraction are inverse operations of each otherInverse Operations - operations that undo each othermultiplication and division are inverse operations of each other Your homework is to complete all of the 1-step and 2-step problems on the front of the sheet and problems #1 - 10 on the back of the sheet. It is attached below. You have your Unit 1 test tomorrow. Please study, study, study! In class we finished going over the remaining problems on the study guide.
Today we reviewed questions #1 - 10 on the Unit 1 Study Guide. Your homework is to complete questions #11-22 and #29-32 on the Study Guide. Your Unit 1 test is Friday 8/19. If there are topics you need help with, please come prepared to ask questions during our last review day tomorrow. We covered our last topic for Unit 1 today: be able to identify how many terms in an expression, list the terms, identify the coefficients, constants and factors.
Today we reviewed our angle definitions. The link to the quizlet we used in class today is
https://quizlet.com/114252557/learn Review the definitions of the following types of angle pairs: vertical, corresponding, alternate interior, alternate exterior, supplementary, adjacent, complementary, same side interior (also known as consecutive interior), same side exterior. Homework: If you did not complete your "parallel city" project during class, complete it at home and turn it in during class tomorrow. Today in class we reviewed adding, subtracting and multiplying polynomials. Tomorrow you have a quick quiz on those topics. Your Unit 1 test will either be Thursday, 8/18 or Friday, 8/19. You received your Unit 1 study guide in class today. Homework is to complete #23 - 28 on your study guide and completely finish the front and back of the "Mystery Message" / "find the perimeter" worksheet. Below are the answers we worked out in class. Today we worked in groups based on what types of transformation questions were answered incorrectly on Friday's quiz. After reviewing and completing classwork students were given their quiz from Friday back to complete corrections.
We introduced Unit 2 - Similarity, Congruence, and Proofs. In 1st block we covered new vocabulary and then started on our parallel lines and transversal foldable. In 4th block we started on our parallel lines and transversal foldable. We covered a lot of new material in class today. It is extremely important that you complete the notes given in class and that you also complete the examples we review in class. Your homework is to complete all problems on the first three sides of your packet. Following is a summary of notes and links from our class today.
Monomial - a number, a variable or a product of a number and variable(s). All of the exponents must be positive integers. Variables are not allowed in the denominator (it is okay to have a constant in the denominator).Polynomial - a monomial or the sum or difference of monomialsBinomial - a polynomial with two terms (two monomials)Trinomial - a polynomial with three terms (three monomials)Like Terms - terms that have the exact same variables and exponents; constants are like terms Adding Polynomials: Combine like terms. The variables and exponents stay the same. Combine the coefficients (the numbers in front of the variables). Please remember your sign rules. When adding numbers with the same sign, keep the sign and add the numbers. When adding numbers with different signs, keep the sign of what you have more of and then take the difference. Subtracting polynomials: Change the signs of ALL OF THE TERMS INSIDE THE PARENTHESIS immediately after the " - " (substraction sign). Then, combine like terms.
