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,...

Data starts to tell a story when it takes shape. Learners describe skewed and symmetric data. They then use the graphs to estimate mean and standard deviation. 

While all light travels at the same speed, each color in the visible light spectrum contains a different wavelength and frequency. Scholars determine the relationship between frequency and wavelength as they complete the activity. They...

Why do we have to do so much work? Scholars learn how to set up bar models to represent a situation involving work. They use these bar models to help set up equations with rational coefficients to solve the problem situation.

Just one step is all you need to find success in solving equations. The 27th installment in a series of 36 teaches how to solve one-step equations involving addition and subtraction. Tape diagrams help future mathematicians in this task.

In the first installment of a 21-part module, scholars build on previous understandings of probability to develop the multiplication rule for independent and dependent events. They use the rule to solve contextual problems.

The key is ... After a day of instruction on key features of graphs, groups create a poster and presentation on the key features of their given function graph. The resource provides an extension activity of "telephone" using...

Write a math story for a series of problems using given variables. The class writes stories, showing understanding of strategies in compound sentences. They then solve the equations.

Young mathematicians first graph a series of quadratic equations, and then investigate how various parts of the equation change the graph of the function in a predictable way.

How can you compare linear functions? The seventh installment of a 12-part module teaches learners how to compare linear functions whose representations are given in different ways. They use real-world functions and interpret features in...

Middle and high schoolers investigate how to solve inequalities. The lesson has a good guide for taking pupils through a direct instruction of the concept. You can use counting tiles in order to help kinesthetic learners.

Students explore some different concepts in relation to using a number line for instruction. Given some number values, they graph the position on the number line. The lesson ends with them playing Bingo.

Seventh graders examine the characteristics of an integer. As a class, they observe a number line and recognize opposite numbers. Algebra tiles, or counters, are used to explore the concept of adding integers. In groups, 7th graders play...

Learners make three dimensional shapes with nets. In this nets lesson, students receive nets which they fold to make a three dimensional object. They predict what shape each net will make and verify it after making the net. They use the...

Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate...

In this second grade lesson your class will practice telling time. The goal is to tell time to five minutes using an analog clock. Your young students count by 5 minute intervals and discuss elapsed time. 

Students explore the concept of linear functions. In this linear functions lesson, students translate linear functions from tables to graphs to equations. Students use an applet to write a function rule for a linear function in...

Eighth graders investigate the Pythagorean theorem and how it is used in geometry. Measurements for different triangles is given and then students must solve problems in order to practice using the formula.

Students define the different methods used for optimizing a particular element of a problem. In this optimization problem lesson, students optimize appropriate details of a problem using data collection, algebra, technology, and/or...

Ninth graders investigate systems of linear equations.  In this Algebra I lesson, 9th graders determine which method is the best for solving a systems:  graphing, substitution, or elimination.  Students choose...

Eighth graders find the range, median, mean, and mode of a data set.  In this finding the range, median, mean, and mode of a data set lesson, 8th graders collect data about the high and low temperature for 10 different cities. ...

Students analyze, create, and record repeating patterns. In this geometry lesson, students create shapes using patterns and keep track of the different shapes. They incorporate transformation and reflections into their patterns.

Students identify angles.  In this angles that pair lesson, students identify adjacent, vertical, complementary, and supplementary angles.  They use straws, pretzel sticks to demonstrate given types of angles. 

Middle schoolers compute area.  In this perimeter, area and volume lesson, students examine given objects and determine the perimeter, area, and volume of each.
