Article on solving systems of equations by elimination using multipication.
Khan video showing algebra application to the idea of midpoint.
In this Khan Academy activity, students will determine which expressions are equivalent to a given exponential expression.
Students estimate the mean and median of a distribution represented by a dot plot or a histogram. Students indicate that the mean is a reasonable description of a typical value for a distribution that is symmetrical, but the median is a better description of a typical value for a distribution that is skewed. Students interpret the mean as a balance point of a distribution. Students indicate that for a distribution in which neither the mean nor the median is a good description of a typical value, the mean still provides a description of the center of a distribution in terms of the balance point.
The purpose of this task is to give students an opportunity use quantitative and graphical reasoning to detect an error in a solution. The equations have been chosen so that finding the exact solution requires significant calculation so that it is easy to make an error.
In this Khan Academy activity, students will practice evaluating function expressions given their graph.
In this Khan Academy activity, students will practice evaluating functions.
In this Khan Academy activity, students will practice evaluating function expressions given their graph.
In this Khan Academy activity, students will evaluate sequences in recursive form.
In this Khan Academy activity, students will evaluate step functions.
This resource provides guided notes about evaluating functions and word problems with practice problems.
In this lesson, students will learn to evaluate a function written as an expression by substituting a value into the given expression. Students will also learn that they can substitute another expression into the original expression of the function. They will recognize that g(x) is the output of a function and the expression x is the input. Students will also evaluate functions using tables and graphs.
A class project examining the effect of outliers on mean and median and which measure of central tendency is the best representation of data.
In this Khan Academy activity, students will construct explicit formulas for arithmetic sequences.
In this Khan Academy activity, students will construct explicit formulas for geometric sequences.
This unit is designed to help students understand the role of parabolas in Algebra and the world around us. Students will be able to create quadratic functions, solve quadratic equations and change quadratic functions to be to go through certain coordinate points. The performance assessment is designed so that students can demonstrate their understanding of quadratic functions. They will be able to use their understandings to create parabolas.
Students explore the key features of the parabola, both geometrically and algebraically.
This lesson is an exploration focusing on the symmetric nature of quadratic functions and their graphs and the interpretation of the key features.
