Eighth Grade Math
Homework Corner
Parents, I am a veteran high school math teacher and will be working hard to do the best for your son/daughter. This page will be updated soon. More important, please email me jmagee@stgab.org, if you have any questions.
Mr. Magee is still building pages and links. Here are the links to 8th Grade Google Classrooms.
If you know the right section and would like to join, BE THE FIRST.

Materials
You will need the following for this course:
Carnegie Learning Course 3 textbook
Carnegie Learning Course3 online textbook
Carnegie Learning Course 3 online skillsbook
Mathia
Binder
Loose leaf
Pencil
Eraser
Grading Pen
Glue Stick
Scissors
Google Classroom
Most days a student will just need their Chromebook for Mathia.
Mr. Magee will let students know if they need their textbook.
Mr. Magee iwll always have pencils, and several different kinds of paper available.
objectives
Students will be able to demonstrate an understanding of congruence and similarity through the following applications.
Verify that angle measure, collinearity, and distance are preserved under rigid transformations.
Prove that two-dimensional figures are congruent if a series of rigid transformations can be performed to map the pre-image tot the image.
Describe a possible sequence of rigid transformations between two congruent figures
Describe the effects of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates
Understand that two-dimensional figures are similar if a series of transformations(rotations, reflections, translations and dilations) can be performed to map the pre-image to the image.
Describe a possible sequence of transformations between two similar figures.
Students will explore angle relationships to perform the following tasks.
Derive the sum of the interior angles of polygons
Explore the relationship between he interior and exterior angles of a polygon
Construct and explore the angles created when parallel lines are cut by a transversal
Students will investigate bivariate data and demonstrate understanding of the following skills
Construct and interpret scatter plots of bivariate measurement data to investigate patterns of association between two qualities.
Generate a use a trend line for bivariate data and assess the line of best fit.
Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects
Use relative frequencies calculated for rows or columns to describe possible association between the two variables.
Students will demonstrate a preliminary understanding of functions and will master the concepts listed.
Explain that a function assigns to each input exactly one output
Determine if a relation is a function
Recognize the graph of linear and non-linear functions
Determine the x-intercept and parameters of a linear function
Interpret the equation y = mx + b as defining a linear function
Recognize that the graph of a linear function has a constant rate of change.
Students will be able to understand the connections between proportional relationships, lines and linear equations by completing the following.
Compare two different proportional relationships
Interpret and draw conclusions of the unit rate as slope and recognize slope as the change in y over the change in x
Explain why the slope is the same between any two distinct points on a non-vertical line in the Cartesian coordinate plane
Derive the equation y = mx for a line through the origin and the equation
y = mx + b for a line intersecting the vertical axis at b
Write a linear equation in point-slope form and standard form using points and slope in the Cartesian coordinate plane.
Students will extend their knowledge of linear equations through the following skills.
Create and identify linear equations with one solution, infinitely many solutions or not solutions
Apply linear equations and inequalities with rational number coefficients including equations and inequalities whose solutions require expanding expressions using the distributive property and combining like terms
Graph systems of linear equations and recognize the intersection as the solution of the system
Explain why solution(s) to a system of two linear equations in two variables correspond to point(s0 of intersection of the graphs
Explain why systems of linear equations can have one solution no solution, or infinitely many solutions
Solve systems of simultaneous equations
Students will explore the real number system and be able to
Generate equivalent representations of rational numbers, including converting decimals which repeat into fractions and fractions into repeating decimals.
Estimate the value and compare the size of irrational numbers and approximate their locations on a number line.
Students will understand and apply the Pythagorean Theorem
Use models to demonstrate a proof of the Pythagorean Theorem
Use the Pythagorean Theorem to determine the unknown side lengths in right triangles in problems in two and three dimensional contexts
Use the Pythagorean Theorem to find the distance between points in a Cartesian coordinate plane.
Students will use integer exponents to accomplish the following
Express very large and very small quantities in scientific notation
Perform operations with numbers expressed in scientific notation
Apply the properties of exponents to generate equivalent expressions
Grading
Grading is done on a point basis. Your final term grade is determined by the total number of points earned.
All test and quizzes are graded anonymously, so the teacher does not know which student's paper it is, until entering the data into the data analysis spreadsheet.
Assessments 60-100 points. Usually 100
Quizzes 30-50 points. Depending on Materail. (Note: If the student earns a higher test grade on the Unit Test that is over the same material as the quiz. The quiz percentage will be raised to match the test percentagel.
In-Class Assignments Typically 10 pts. If a student does not finish an in class assignment in class, they should finish it for homework, and hand it to Mr. Magee, the next day in Class.
Mathia 10-20 points. Students should either be caught up by their APLSE score or Mr. Magee can give a at level workspace number if requested.
