It's raining (systems of) cats and dogs! The fifth unit in a nine-part course presents systems of equations and inequalities within the context of pets. Scholars use systems of inequalities to represent constraints within situations...

Your learners will enjoy this simple summary of finding and graphing the solutions to variable inequalities. 

Which number is bigger? Using a variety of activity sheets, this unit starts with the basics of inequalities and progresses through solving compound linear inequalities. Problems cover the range of inequalities including inequality word...

Your learners will appreciate the complete picture of linear inequalities presented in this lesson plan. Starting simply with definitions and moving all the way to solving linear inequality word problems this activity is simple to...

Activate the strengths of your visual learners using an informative lesson. In the 15th installment of the series of 28, pupils graph their solutions on number lines to create a visual representation of solutions. Problems presented as...

Help learners get their facts in line to build and solve complicated linear equations and inequalities. Pupils build upon their knowledge of solving basic equations and inequalities to solve more complex ones. Individuals work with...

Your young graphers will collaboratively play their way to a better understanding of the solution set produced by the combining of inequalities. Cooperation and communication are emphasized by the teacher asking questions to guide the...

Perry the penguin wants to buy a new scooter, but he doesn't have any funds! Walk your kids through the short book Less Than Zero, and have them track his borrowing, spending, and saving on a line graph while you read. Pupils will learn...

Can you solve an equation graphically? Absolutely! This Algebra II lesson makes the connection between solving an absolute value equation and graphing two functions. Graphing absolute value functions is presented through the process of...

This inequality word problems activity is ideal to assess your learners' understanding of inequality and linear concepts around solving and writing equations and inequalities. Equations, graphs and real-life scenarios are used to...

This resource is part of a series which expects participants to be familiar with graphing inequalities on a number line. It is a word problem that asks your class to graph a discrete solution set and interpret it in the context of an...

Your algebra learners write linear, exponential, and quadratic equations containing the same two graph points in this collaborative task.

Skeeters are used to model linear and exponential population growth in a wonderfully organized lesson plan including teachers' and students' notes, an assignment, graphs, tables, and equations. Filled with constant deep-reaching...

An intersection is more than just the point where lines intersect; explain this and the meaning of the intersection to your class. The 26th segment in a 33-part series uses graphing to solve systems of equations. Pupils graph linear...

Larvae transportation on the New England seamounts is based on the density of the water. Scholars calculate density and graph salinity versus temperature to better understand the distribution of organisms in a water column....

A discussion begins a lesson on comparing numbers. Pupils explain how they can show a number, then visit math centers to explore number-making tools. A story read-aloud of More or Less by Stuart Murphy identifies language for...

Students work in pairs to test the strength of spaghetti strands. They collect and graph data to determine a line of best fit. Students create a linear equation to interpret their data. Based on the data collected, students predict...

Many students like to play sports and the equipment that goes with it costs money. The resource sets up an inequality that gives a total amount needed to purchase the equipment and the initial amount of money already obtained. In order...

When complicated algebraic expressions are involved, it is sometimes easier to use a table or graph to model a context. The exercises in this lesson are designed for business applications and require complex algebraic...

According to the resource graph, which costs more: peaches or plums? Algebra learners compare two proportional relationships and then throw in a banana. Leaving out the scale helps students become intuitive about graphing. 

Don't shoo away the resource on shoes. Given constraints on the amount of leather and string needed to make two different types of shoes, learners graph a system of inequalities for the situation. They then determine the maximum profit...

How do doctors predict a child's future height? Scholars use one case study to determine the height of a child two years into the future. They graph the given data, determine the line of best fit, and use that to estimate the height in...
