8th Grade Math
Ms. Daniel
MNPS Mathematical Mission
Provide each student with the daily opportunity to reason mathematically, communicate their ideas with others, and value mathematics through rigorous instruction.
Overview of Grade 8 Mathematics
The Number System
This is the culminating area for the number system from 6th and 7th grade. Students now know there are numbers that are not rational, called irrational numbers. Students approximate irrational numbers by rational numbers locating them on a number line and students estimate the value of irrational expressions.
Expressions and Equations
Students work with radicals and integer exponents. Students understand the connections between proportional relationships, lines, and linear equations.
Students recognize equations for proportions
(y/x = m or y = mx) as special linear equations (y = mx + b), understanding that the constant of proportionality (m) is the slope, and the graphs are lines through the origin.
Functions
This begins the formal study of functions, a mathematical concept that for the student will
continue throughout high school. Students grasp the concept of a function as a rule that assigns to each input exactly one output. They understand that functions describe situations where one quantity determines another.
Geometry
Students use ideas about distance and angles and how they behave under translations, rotations, reflections, and dilations, to describe and analyze two-dimensional figures and to solve problems. Students understand the statement of the Pythagorean Theorem and its converse and can explain why the Pythagorean Theorem holds. They apply the Pythagorean Theorem to find distances between points on the coordinate plane, to find lengths, and to analyze polygons. Students complete their work on volume by solving problems involving cones, cylinders, and spheres.
Statistics and Probability
Students extend their knowledge from 7th grade by working with scatter plots for bivariate data and understand linear associations and the use of linear models to solve problems interpreting the slope and intercept. Students continue work with probability by finding probability of compound events and red present the data using organized lists, tables, and tree diagrams.
Classroom Norms
Students are expected to follow all school rules. Inside this classroom students should:
#follow- all directions
#deadlines- turn in your assignments when they are due
#goals- make learning a priority
#respect- show it for yourself and others
#get involved- class participation is required
#positive- attitude… don’t show up with one
#beatthebell- show up on time
#noexcuses- take personal responsibility for your actions
#notyourmaid- clean up after yourself
Grading
Students will be graded on the following: Homework, Class Projects, Test/ Quizzes, and Classwork.
Homework Policy
When homework is assigned, it is to be completed immediately.
Late/Make Up/ Retake Work
If a student should miss a day of class, they need to check the Schoology page for that day’s assignments. However, the policy has always been… if you miss a day, you have one day to make up work; if you miss two days, you have two days to make up work; etc… Students are encouraged to check the Schoology page daily, so they do not get behind on their studies.
