Curated OER
Inequalities 7.3
Graph inequalities and discuss the difference in their slopes. Learners observe rate of change as they compare linear, quadratic, and cubic functions.
Curated OER
Patterns Everywhere!
Learners recognize and demonstrate the patterning of numbers and objects in our environment. They create a pattern using geometric shapes and find a missing number in a sequence.
Curated OER
Clock Arithmetic and Cryptography
Learners investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.
Curated OER
Translations, Reflections, and Rotations
Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.
Curated OER
Graphing and the Coordinate Plane
Students gain practice reading coordinates and plotting points by participating in the Coordinates! Game. They demonstrate and test their skills with graph paper and the Maze Game.
Curated OER
Color, Computers, and Math
Students visit a web page that gives a brief introduction to two color models and experiment with mixing different color intensities to create different colors. They visit links that give more detailed information on color.
Curated OER
Famous Public Properties
Students identify and use the commutative properties of addition and multiplication, associative properties of addition and multiplication, and the distributive property of multiplication over addition.
Curated OER
I want a credit card--or do I?
Students pretend to borrow $1000.00 on a credit card. They pretend to make the minimum payments for a year. When they're done, they make a pie chart showing how much of their payments reduced their debt, and how much was interest.
Curated OER
Volume and Surface Area: Which Is More?
Students explore the volume and surface area of three dimensional figures. Through the use of video, students discover three dimensional shapes, their uses in real-life applications, and methods used to calculate their volume and surface...
Curated OER
What Can I Afford?
Learners explore the costs of various cell phone plans, and various types of banking accounts to determine which one would yield the highest returns if the money saved from the cell phones were placed in different accounts.
Curated OER
A Geological Puzzle
Students compare and contrast the various types of rocks on each continent. In groups, the calculate the rock ages and types to determine if the continents, in their opinion, were joined at one time. They develop two imaginary...
Curated OER
How Long Can You Go?
Eighth graders examine the usefulness of a line of best fit by collecting and graphing data, using a graphing calculator to determine the line of best fit, and making a variety of predictions. They watch a video, then design a...

Slope Investigation
Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs...
Curated OER
Ratios, Rates, Percent and Nutrition
Examine food labels to determine percentage of fat and sugar to total calories with middle schoolers. Daily nutritional guidelines are discussed and learners will decide how well their foods fit into a healthy diet. In the provided...
Curated OER
Make a Math Mascot
Create a math mascot by identifying irrational and rational numbers. Learners will also solve linear equations.
Curated OER
Measuring Perimeter
Have your class practice measuring the perimeter of various objects using this resource. Fifth graders place various-sized polygons in order (from largest to smallest). They use non-standard measuring tools to estimate the distance...
Curated OER
Left Hand, Right Hand - Solving Systems of Equations
Students compare the speed at which they write with their left hand to the speed at which they write with their right hand. The experiment serves as a vehicle to help students develop a conceptual understanding of the three different...
Curated OER
Skeeter Populations and Exponential Growth
Students perform investigations on the growth of populations and use exponential functions to represent that growth. They watch a video clip of growth patterns. Students work in groups to determine the "population" of each color of...
Curated OER
Curses and Re-Curses! It's Happening Again.
Students study basic recursion by exploring patterns in the data they generate from two simple probability-based experiments. In the first, students flip a coin to discover how many times they must flip it before it lands on "heads."...
Curated OER
Relating Division and Subtraction
Third graders relate the process of division to subtracting equal groups. Through guided practice and teacher demonstration, they complete division problems using a subtraction method. Students complete problems independently for...
Curated OER
Functions Made Easy
Students explore concept of functions as relationships, as machines, as equations, and as graphs.
Curated OER
Giggle, Giggle, Quack Pizza Fractions
Students explore the concept of multiplication by using pizza. They read an article discussing how math is used everyday. They try to determine how many pizzas they would need to feed the class.
Curated OER
Graphs and Functions
Students are introduced to plotting functions on the Cartesian coordinate plane seen several categories of functions, including lines and parabolas
Curated OER
Patterns In Fractals
Students find number patterns in the generation of several different types of fractals.
