Without data, all you are is another person with an opinion. Show learners the power of statistics and probability in making conclusions and predictions. Using two-way frequency tables, learners determine independence by analyzing...

Don't leave your classes vulnerable in their calculations! Help them understand the importance of calculating a margin of error to represent the variability in their sample mean. 

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

Medians, midsegments, altitudes, oh my! Pupils study the properties of the median of a triangle, initially examining a proof utilizing midsegments to determine the length ratio of a median. They then use the information to find missing...

Learn transformations through constructions! Pupils use perpendicular bisectors to understand the movement of a reflection and rotation. They discover that the perpendicular bisector(s) determine the line of reflection and the...

Exponentially increase your pupils' understanding of exponents with an activity that asks them to explore the meaning of exponential notation. Scholars learn how to use exponential notation and understand its necessity. They use negative...

Uncover the properties of translations through this exploratory lesson. Learners apply vectors to describe and verify transformations in the second installment of a series of 18. It provides multiple opportunities to practice this...

Investigate the results of multiple translations on an image. Scholars use vectors to perform a sequence of translations in the seventh lesson plan of 18. They examine the results and determine the importance of using a sequence rather...

Can you support the argument that the decimal 0.99999 ... is equivalent to the number one? The seventh installment in this 25-part module gives convincing support for this conclusion. Pupils write infinite decimals using powers of 10....

The truth is always best. Individuals continue to find values that make equations true in the 26th installment of the 36-part module. The only difference is that they now call them solutions to those equations.

Subtraction, take away, and compare the difference are the topics of this comprehensive presentation. Budding mathematicians will count balls, then watch as they are taken away. They will then view two sets of balls and compare the...

Using a Smart Board, or a plain ol' white board or chalkboard, the teacher pulls up a grid and demonstrates how squares and rectangles can be divided up into equal parts. The class will get their own graph paper to draw shapes and divide...

Pupils use blocks and markers to illustrate the processes of adding, subtracting, multiplying and dividing integers. In this mathematics lesson plan, learners use Algebra blocks to demonstrate multiplying polynomials.

Upper grade and middle schoolers explore mathematics by participating in a measuring activity. They hypothesize on what the average height of a male or female 6th grader is and identify ways to find the average mathematically. Learners...

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...

Bring three-dimensional shapes to life in your classroom. First introduce the vocabulary of three-dimensional shapes, such as sphere, cube, and pyramid. Then, show your kids examples of how to use two-dimensional objects draw...

Here is an app that will help kids sort objects! Sorting is an action that promotes cognitive flexibility and executive function. It is a key skill used in categorizing scientific data, making generalizations, and is foundational in...

You and your class will like this lesson on using visual models to relate the volume and surface area of solid shapes. Learners construct three-dimensional forms using nets. They calculate the surface area and volume for each and then...

Explore the concept of the equals symbol. In this mathematical symbols activity, learners discover the meaning of the equals sign (symbol). They also construct addition and subtraction sentences to understand the concept of equal parts.

While this lesson focuses on a study of the Hudson River, it could be used as a template for a discussion of map skills, converting measurements, and plotting a route. The lesson includes vocabulary and other resources to make it a...

Students get the opportunity to investigate the concept of data collecting. They explore how to tally and read a bar graph. Vocabulary about data is also be included. At the end of the lesson, individual students collect data independently.

Middle schoolers investigate the mathematical concept of absolute value by counting the number of steps taken in two directions. Using the number line the teacher can note how they can forward and backward without changing the absolute...

After completing the activities included here, your beginning foreign language speakers will be able to name family members, identify a family's place of origin, and write short sentences about family members. They start by listening to...
