There's nothing negative about this mini-unit on integers! Engaging young mathematicians in a series of hands-on activities and collaborative learning opportunities, this resource offers an excellent way to introduce your class...

Just because one integer is larger than another doesn't mean it will make sense right away. Go beyond note taking and show learners, through the use of algebra tiles and a Four-Pan Algebra Balance, how the numbers relate to one...

A well-rounded unit on positive and negative integers is a great addition to your middle school math class. Learners work through five activities, each focused on a different skill, before playing a Game of Life to practice the...

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

Take steps into sequences. An 11-lesson unit builds upon pupils' previous understanding of writing expressions to develop the idea of sequences. The resource explores both arithmetic and geometric sequences using recursive and explicit...

Sequences are all about recognizing patterns. A module of 11 lessons builds pupils' understanding of sequences through pattern analysis. The practice connects the analysis to linear and exponential equations. This is the first module in...

Time to study the most sensible function — rational functions! The seven-lesson unit develops the concept of a rational function through a connection to rational numbers and fractions. Scholars graph functions, solve equations, and...

Solve conceptually challenging absolute value problems. In order to succeed at these problems, you'll need to remember that the absolute value of the difference of two numbers is the distance between those numbers. Students receive...

This tutorial on signed numbers features lesson plans, practice pages, examples, application problems, and interactive work. Teacher resources include overhead manipulatives, card games, a Bingo game, and graphing calculator downloads.

This resource has three problem sets to practice subtraction. Select a problem set, then select a question. Fill in the blank with the correct answer for each problem. When you have answered all of the questions, ask Charlie how you did.

Practice solving challenging negative number addition and subtraction problems. Number line models, variables, and absolute value come together to push your knowledge of negative numbers even deeper (maybe even below zero!). Students...

Students learn how to subtract integers. The resource consists of notes, detailed examples, and practice problems with solutions.

This site is a tutorial for students in algebra 2 or for those who need a refresher. The site has explanations, definitions, examples, practice problems and practice tests are found covering topics such as linear equations, graphing,...

Practice identifying equivalent expressions involving the addition and subtraction of negative numbers. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
