These interactive lessons use dynamic graphing and guided discovery to strengthen and connect symbolic and visual reasoning. They give the student a hands-on visual exposition of all Common Core Algebra 1 topics, reinforced by adaptive exercises and randomly generated tests. All exercises and tests are checked and graded automatically. Hover the mouse over a link below to see an example from that lesson, or click on a test link to see a concise summary of a group of lessons. Relevant standards are listed after each lesson’s exercises, with a ' (prime) denoting a distinct link. We also provide a course glossary .
The Common Core and other standards cover many algebraic topics before the first actual High School Algebra course. Therefore, students may have already completed many of the lessons and exercises below in an earlier grade, or in a summer preparatory course . If so, those assignments will be treated as already completed in this course also.
Students should have scratch paper available, access to (software or hardware) numeric calculators except during the Arithmetic Review chapter, and other students or a teacher to ask for help when they are stuck. All students are encouraged to both give and receive mathematical explanations with their peers. Please send us your comments, questions and suggestions.
Variables, expressions, and simple equations, linear graphs, inequalities, absolute value, and square roots, descriptive statistics, systems of linear equations or inequalities, quadratic expressions, graphs, and equations, the pythagorean theorem, exponential growth and decay.

Algebra 1 – arithmetic sequences.
Arithmetic sequences is a part of syllabus in algebra 1 (second math course), which finds application in many algebra questions including algebra word problems. An arithmetic progression (AP) or arithmetic sequence is a sequence of numbers, whose consecutive numbers differ by a constant. When n terms of an arithmetic sequence are added, you get arithmetic series. Arithmetic series formula is given by : sum = n/2 (a + l) where a is the 1st term and l is the last term.

What is a recursive formula for an arithmetic sequence.
Recursive formula: This sequence is neither arithmetic nor geometric. It does, however, have a pattern of development based upon each previous term. Notice how the value of n is used as the exponent for the value (-1).
Imagine we want to find a formula for the nth term of this sequence: 7, 11, 15, 19, 23, … We can see that the terms in this sequence go up by 4 each time, so 4n must appear in the formula. The sequence generated by the formula 4n is the four times table, but it isn’t quite the sequence we want: 4n sequence:
A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1. The process of recursion can be thought of as climbing a ladder.
To find the common ratio, divide the second term by the first term. Notice the non-linear nature of the scatter plot of the terms of a geometric sequence. The domain consists of the counting numbers 1, 2, 3, 4, … and the range consists of the terms of the sequence.

The study of mathematics begins with the study of patterns. You can find all kinds of patterns in the world around you. There is a pattern in how the size of the population in your home town grows. There is a pattern in how the temperature rises and falls throughout the day. In this module, you will explore arithmetic patterns and geometric patterns in the world around us, and use mathematics to explain and apply the patterns you discover.
By the end of this module, you will be able to:

This unit revolves around the concept of equivalency. Within this larger framework, we review and develop the real number properties and use them to justify equivalency amongst algebraic expressions. Students get work in mindful manipulation of algebraic expressions and actively seek structure within expressions to understand equivalency.
