One of my review topics for Algebra 2 was graphing ordered pairs and linear functions.
We covered this thoroughly in Algebra 1, but I know One of my favorite pages from this year was our Solving Systems of Equations page. In my opinion, this page was truly interactive. Students were sorting, classifying, and studying with these notes.
This page took a few days to complete. First, we discussed solving systems graphically. They were still connected as one piece of colored paper. Students then put those notes away in their…. All the systems of equations were in slope intercept form and intended to be solved by graphing. However the systems could have also been solved by substitution or elimination. This activity was so much more fun than a normal Math worksheet.

Factory Functions.A relation is a set of ordered pairs. When both sets are numerical, it is possible to graph the relation. When it is possible to graph the relation, we can analyse the trends in the data visually — say what is the maximum value, the minimum value, when the values are increasing, decreasing, staying steady and so on. Example: The height of a capsule on the London eye Ferris Wheelt minutes after boarding. The purpose of this project is to become familiar with the vocabulary and concepts used in math when discussing relations, and to become familiar with graphing on geogebra or on desmos.
Page 1: Title of project, Author youDate today and Introduction. The first step is to decide what numerical relationship to graph. For the purpose of this project, we will use data that changes over time. You just need to think of something that changes over time that you have some familiarity with.
Algebra 1 Project Ideas
Here are some ideas:. Record the data on a Google Sheet or draw a table on paper. The first column should be time — possibly minutes, days, months or years. Time can be an awkward quantity, not base 10, months are not of equal length etc so ask if you have questions on how to record the time.
The second column should be your data values. Use graph paper, decide how to draw your axes, label your axes, plot your points and give the graph a title. A statement regarding which variable is independent horizontal axis and which is dependent vertical axis. The domain of the relation you graphed starts …. The minimum value of your data points, the maximum value of your data points, whether or not if you collect data again you might get other values.

Students explore linear, quadratic, and exponential functions, and develop a deep understanding of the features of each function—graphically and algebraically—as they create models and analyze situations.
Students primarily explore linear functions as well as linear piecewise, absolute value, and step functionsquadratic functions, and exponential functions. Within these parent functions, students develop a deep understanding of the features of each function—graphically and algebraically—and use these to guide creation of models and analysis of situations.
In Unit 1, Functions, Graphs, and Featuresstudents are introduced to all of the main features of functions they will learn throughout the year through basic graphical modeling of contextual situations. Students will learn function notation and use this to analyze and express features of functions represented in graphs and contextually.
Students will use the tools of domain and range, rates of change, intercepts, and where a function is changing to describe contextual situations. In Unit 2, Statisticsstudents continue to analyze contextual situations, but in this unit, they focus on single-variable data and then bivariate data. This is the first unit where students are introduced to the concept of using data to make predictions and judgments about a situation.Input type=time with seconds
Univariate data is described through shape, center, and spread by using mathematical calculations to support their reasoning. Students begin to make judgments about whether data is consistent analysis of spread and whether mean or median is a better representation of a situation center. Bivariate data is analyzed for whether the variables are related correlation and whether a linear model is the best function to fit a set of data analysis of residuals ; students also develop a linear model that can be used to predict future events.
In Unit 2, students are introduced to the modeling cycle and complete a project on univariate data analysis and another on bivariate data analysis. The understanding students develop in this unit builds the foundation for Unit 4, Unit 5, and Unit 6, as well as provides an algebraic outlet for modeling contextual situations started in Unit 1 and continued in Unit 2.
In Unit 4, Linear Equations, Inequalities, and Systemsstudents become proficient at manipulating, identifying features, graphing, and modeling with two-variable linear equations and inequalities. Students are introduced to inverse functions and formalize their understanding on linear systems of equations and inequalities to model and analyze contextual situations.
Proficiency of algebraic manipulation and solving, graphing skills, and identification of features of functions are essential groundwork to build future concepts studied in Units 5, 6, 7, and 8. In Unit 5, Piecewise Functions and Transformationsstudents revisit work in Units 1, 3, and 4 to formalize their understanding of domain and range to model linear piecewise functions.
The algebraic work done in Units 3 and 4 build to working with absolute value functions. Students are introduced to the concept of a function transformation—a key concept in identifying functions that model situations but are shifted, reflected, or dilated to represent the characteristics of the particular situation.
Absolute value functions are used to bridge piecewise functions and provide a low-entry parent function to understand how different function transformations are represented algebraically and how domain and range are affected by transformations. In Unit 6, Exponents and Exponential Functionsstudents review exponent rules studied in middle school and extend their understanding to include rational exponents.
In this unit, students will be operating with polynomials as an extension of work done in Unit 3 with expressions, and utilizing exponent rules reviewed in this unit.
Students formalize the conceptual understanding of the power of exponents to increase or decrease values at increasing or decreasing rates, respectively, to model with exponential functions. Students use the understanding about linear functions developed in Units 2, 3, 4, and 5 to make comparisons to exponential situations in terms of algebraic modeling, use of the function in contextual situations, and graphical analysis. The understanding from this unit carries through to quadratics as well as into Algebra 2 with exponential modeling and logarithms.
In Unit 7, Quadratic Functions and Solutionsstudents begin a deep study of quadratic functions—a key function for students to master in Algebra 1.
Students pull together their understanding of graphical analysis from Unit 1, algebraic manipulation from Unit 3, and linear equations and inequalities from Unit 4 to develop an understanding of what a solution means in context, graphically, and algebraically within quadratics. The concepts learned in this unit will be directly applied in the next unit and throughout Algebra 2, where students will be expected to be fluent in analyzing and solving quadratic functions and equations.
In Unit 8, Quadratic Equations and Applicationsstudents wrap up their study of quadratic functions in Algebra 1, diving deep into all forms of quadratic equations, methods to solve quadratic equations, and methods to identify features from equations.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials.

It should be mentioned immediately that this is unlikely. The company is closely-held by the Coates family and every indication is that it wishes that to remain the case. Indeed, quite the opposite is true. Much has been made in the gambling press of the slowing rate of NGR growth. If bet365 was listed we would have more colour on the geographic split of the current earnings and perhaps an idea of the differing growth rates.
The splits count because of how they would affect the valuation of the business.
