Scaling is a practical skill as well as a topic to be addressed throughout the Common Core math standards. You are given three different presentations and a detailed teacher's guide to use while teaching proportion, as well as practice...

Examine the power of technology while modeling with polynomial functions. Using the website wolfram alpha, learners develop a polynomial function to model the shape of a riverbed. Ultimately, they determine the flow rate through the river.

Examine numbers in scientific notation as a comparison of size. The 14th lesson in the series asks learners to rewrite numbers as the same power of 10 in scientific notation to make comparisons. Pupils also learn how to use a calculator...

Join together to investigate truss joints. Scholars learn how to analyze forces at truss joints to determine the strength of truss bridges. They apply the "method of joints" in calculating the tension and compression forces at each joint...

How can you tell if a number of items is reasonable? Combine math and language arts with a fun lesson based on Jeff Shepard's The Right Number of Elephants. After reading the book, kids discuss amounts of other items and create...

Master place value with a series of lessons that use math journals, manipulatives, and place value mats. Kids follow the instructions to represent numbers of all sizes with base ten blocks and recording sheets. 

Visual models support young mathematicians with exploring equivalent fractions. Starting with a quick warm-up problem, children go on to work through a series of guiding practice problems before working with a partner identifying and...

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

Have young mathematicians subtracting fractions in no time with this manipulative-based math lesson. Using their sets of fraction circles, young scholars explore a number of word problems involving the subtraction of fractions before...

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

Some lessons feature videos, some interactive practice problems, and some have notes and activities. This comprehensive look at factoring and solving polynomial equations using the zero product principle has all of this and more. Though...

Discover an inverse variation pattern. A simple lesson plan design allows learners to explore a nonlinear pattern. Scholars analyze a distance, speed, and time relationship through tables and graphs. Eventually, they write an equation to...

Provide guidance and practice of the useful skill: solving rational equations using both an algebraic and graphical approach. Pupils solve increasingly more difficult rational equations using algebraic methods. After, they...

Augment a unit on parabolas with an instructive math activity. Pupils graph parabolas by examining the relationship between the focus and directrix. 

From derivatives to antiderivatives and back again. Building on the second activity of the three-part series covering functions, learners explore the concept of an antiderivative. They connect the concept to the graph of the function and...

Say cheese! Can your class take a great photo and size it to fit any need? A career and technology-centered lesson plan demonstrates the correct way to resize images in Adobe Photoshop. Scholars view a presentation and work individually...

Get to know your class and teach about data analysis all with the help of Google Docs. Using student-generated questions, create a class survey using Google Forms. Reserve time in the computer lab for learners to complete the form and,...

Do you need to graph lines to see the point? A thorough lesson plan provides comprehensive instruction focused on solving systems of equations by graphing. Resources include guided practice worksheet, skill practice worksheet,...

Science, technology, and math come together in this one combination exercise. Analyzing the common soda can from both a purely mathematical perspective and a scientific angle allows for a surprisingly sophisticated comparison of...

Not all variables are created equal. Discover how variables in computer science are different from variables in math class. Scholars learn to work with variables in computer programming by developing a mental model for how variables...

Put everything together in a picture. Scholars take what they learned in the previous three lessons in the 15th segment of a 23-part unit to graph rational functions. They find the end behavior, the horizontal and vertical asymptotes if...

Many things in life take the shape of a polynomial curve. Learners design a polynomial function to model a riverbed. Using different strategies, they find the flow rate through the river.
