Analyzing Residuals (Part 1)
Just how far off is the least squares line? Using a graphing calculator, individuals or pairs create residual plots in order to determine how well a best fit line models data. Three examples walk through the calculator procedure of...

Transformations in the Coordinate Plane
Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

The Window Problem
Students identify patterns and compute formulas to solve the problems. In this algebra lesson, students come up with a rule given a pattern, and analyze the relationship between data and graphs.

8.SP.1Texting and Grades I
Here is a fitting question for middle schoolers to consider: Is there a relationship between grade point average and frequency of sending texts? Starting statisticians examine a scatter plot and discuss any patterns seen.

A World of Symmetry: Math-Geometry
Define and identify the three basic forms of symmetry translation, rotation, and glides with your class. They cut out and arrange paper pattern blocks to illustrate symmetry, create a Cartesian graph, and design a rug with a symmetrical...

Tiling Tessellations
Students explore tessellations. For this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.

The Kangaroo Conundrum: A Study of a Quadratic Function
Pupils play a game and collect data for their graph. For this algebra lesson, students solve quadratic equations and identify properties of their graph. They describe the pattern created by the graph and the game.

Slopes of Lines
Learners examine a graph and relate it to the real world situation it depicts. They investigate changes in an equation and the appearance of a line. They investigate the connection between the graph of a situation and the meaning of the...

Analyzing Residuals (Part 2)
Learn about patterns in residual plots with an informative math lesson. Two examples make connections between the appearance of a residual plot and whether a linear model is the best model apparent. The problem set and exit ticket...

4c and 7c Stamps
Fifth graders determine what it takes for a sequence of numbers to carry on infinitely. They examine patterns that can be made using linear combinations of 4 and 7 based on the use of four cent and seven cent stamps. They use appropriate...

Cups and Cubes
Third graders explore the use of cups and counters as a model to analyze the effects of operations. They create and use a rule to create a sequential pattern and use cups and cubes to model the relationship.
