Students 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.

Students use several examples to create a method for adding and subtracting fractions with unlike denominators. They present these methods to the class and then practice applying methods to sample problems.

Students explore the concept of modular arithmetic and cryptography. For this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Students exchange their...

Learners explore the concept of fractions. For this fractions lesson, students perform basic operations such as addition and subtraction with fractions. Learners play a game on the computer called 'Fraction Four' that gives students...

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...

Seventh graders create a graph of their Christmas gifts. They develop categories, compute fractional and decimal parts for each category, identify the number of degrees to represent each fractional part, and create a circle graph to...

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

Eighth graders demonstrate the mathematical components of a scientific problem as well as illustrate how real world problems can be solved using math. They demonstrate math skills such as rate calculation, graphing, and linear equations.

In this geometry instructional activity, 10th graders analyze and solve logic puzzles.  The one page interactive instructional activity contains five multiple choice questions, provides a hint, and is self checking.

What do you do with a difficult-to-factor quadratic expression? This lesson provides the answer. Pupils learn a grouping strategy to help factor trinomials. When guess and check seems too tedious, this method is the "works every...

In this worksheet, learners identify the Fundamental Theorem of Algebra. They solve polynomial functions and simplify expressions and equations. 

Young scholars create an illustration of how to solve math problems. They use appropriate resources for solving the problems. Students have to demonstrate how drawing diagrams and using pictures can help them by using KidPix. On Slide...

Students compute minimum velocity, using square roots.

Students pretend they are about to buy their first new car. They must do all the calculations necessary to estimate the cost of purchasing the car. They see that the math they learn in school really does have real-life applications.

Third graders create a box big enough to hold a million dollars. This is a project fun to do near the winter holidays with inexpensive gifts included in the boxes. This hands-on lesson very effectively demonstrates the concept of volume.

Eighth graders practice calculating problems using addition, subtraction, multiplication and division. They estimate solutions to algebraic problems. They also graph their solutions.

Learners create charts and graphs using a spreadsheet. They chart the number of each gift given day by day from the song, "The Twelve Days of Christmas." They create a bar graph and a circle graph from their data on the spreadsheet.

In this math worksheet, students find the solutions to the problems that coincide with each Algebra objective. They simplify the expressions.

In this Algebra II worksheet, 11th graders solve equations involving radical equations.  The worksheet provides an explanation and worked examples.  The two page worksheet contains three problems.  Solutions are not...

In this fractions activity, learners put fractions into their simplest form, write as improper fractions, add and subtract, estimate amounts, and more. They complete 31 problems.

Students explore and examine the increases and/or decreases for water user groups: irrigation, municipal, manufacturing, steam electric power generation cooling, livestock, and mining. They utilize percentage changes during their...

In this math worksheet, students read about and learn the properties of addition. Students study the commutative, associative, identity and inverse properties. There are no problems on this page for students to solve.

Students are introduced to mixed expressions and complex fractions. They work through several problems with the instructor and then complete a worksheet.

Get independent practice multiplying rational numbers. Each incorrect response gets a text box explanation and another try. Correct responses are confirmed.
