What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

How do you summarize data that cannot be averaged? Using an exploratory method, learners complete a two-way frequency table on super powers. The subject matter builds upon 8th grade knowledge of two-way tables. 

It is all relative, or is it all conditional? Using an exploration method, the class determines whether there is an association between gender and superpower wish through the use of calculating conditional relative frequencies. The...

If you can multiply multi-digit integers, you can multiply polynomials. Learners use an area model to compare multiplying numbers to multiplying polynomials. They progress to using the distributive property. 

Build a true understanding of division of polynomials. Learners use their knowledge of multiplying polynomials to create an algorithm to divide polynomials. The area model of multiplication becomes the reverse tabular method of division.

Have young mathematicians create new identities! They explore the even/odd, cofunction, and periodicity identities through an analysis of tables and graph. Next, learners discover the relationships while strengthening their...

Tables are useful for more than just eating. Learners use tables to organize data and calculate probabilities and conditional probabilities. 

(vegetable)^(1/2) = root vegetable? The fourth installment of a 35-part module has scholars extend properties of exponents to rational exponents to solve problems. Individuals use these properties to rewrite radical expressions in...

The Function That Shall Not Be Named? The eighth installment of a 35-part module uses a WhatPower function to introduce scholars to the concept of a logarithmic function without actually naming the function. Once pupils are...

There's no place like home. Future home owners investigate the cost of buying a house in the 33rd installment of a 35-part module. They come to realize that the calculations are simply a variation of previous formulas involving car loans...

Class members perform complex operations on a plane in the 17th segment in the 32-part series. Learners first verify that multiplication by the reciprocal does the same geometrically as it does algebraically. The class then circles back...

The key to understanding is making connections. Scholars explore angle dilations using properties of parallel lines. At completion, pupils prove that angles of a dilation preserve their original measure. 

Students practice addition and subtraction. In this fact families unit, students practice finding sums and differences for fact families. This unit includes ten lessons with science and social studies integration.

Third graders investigate shapes in our world. In this geometry lesson plan, 3rd graders describe plane and solid shapes and identify angles, solid objects and lines of symmetry. Students use online resources, graphic organizers and...

Second graders view a model of a survey and tally.   In this survey and tally lesson, 2nd graders decide on questions for a survey.  Students conduct the survey and tally their results. Students create a tally chart....

First graders listen to Shapes and The Greedy Triangle to identify and describe examples of geometric shapes.  In this geometric shapes lesson, look for geometric shapes in real world places.  Students make a mobile of shapes...

Yummy! Use Twix candy bars to teach a lesson in comparing length! Learners will love this lesson and you will be addressing Common Core standards at the same time!

Students review number sets and complete a Venn Diagram for number sets. In this number sets lesson, students review integers, whole numbers, and elements. Students use computers to create a Venn Diagram for number sets. Students...

Students explore the concept of probability in sports. In this probability in sports instructional activity, students research a sport that they enjoy. Students find probability information related to their sport. Students share their...

High schoolers explore the concept of linear functions. In this linear functions instructional activity, students translate linear functions from tables to graphs to equations. High schoolers use an applet to write a function rule for...

Students study how to calculate elapsed time. In this elapsed time lesson, they determine how to calculate the ending time of an event when they are given the starting time and the elapsed time. They participate in direct instruction,...

Students investigate modular arithmetic and how to use it to solve real world problems. In this modular arithmetic lesson, students use computers to work on modular arithmetic after a teacher guided lesson. They complete guided practice...
