Students are taught how to add and subtract and use number sense to solve basic math problems. For this addition and subtraction lesson, students are being taught using theories from different philosophers in education. They are given a...

Explore the connection between fractions and rational expressions. Young scholars manipulate fractions with unlike denominators to find a total. Challenge questions allow them to check their work to ensure they are correct.

Investigate the process of combining like terms using an interactive animation. Scholars tackle simplifying expressions by manipulating rectangles that represent the terms. They add and subtract terms to arrive at the result.

Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another...

There's a fine line between a numerator and a denominator! Learners find common denominators in order to add and subtract rational expressions. Examples include addition, subtraction, and complex fractions.

Astronomers practice downloading data from a high-energy satellite and translate the data into colored or shaded pixels. As a hands-on activity, they use pennies to simulate high-energy satellite data and they convert their penny...

Students work with rectangles to find generalizations for adding and subtracting odd and even numbers in part one of the lesson. In part two, students use geoboards to construct polygons, look for patterns, and find a general rule.

Investigate vectors and learn how to use them. Explore why size and direction, as well as knowing speed and distance, are important components of the vector problems you are trying to solve. This is an extensive instructional activity...

Six pages prepare you to introduce your math stars to the addition and subtraction of positive and negative numbers. They drive a robot back and forth on an actual number line to represent the operations. If you don't have access to a...

Your statisticians examine the characteristics of conditional probability and the probability of simultaneous independent events. They perform computer activities to find probabilities for simple compound events. They examine the...

Learners sometimes struggle to understand the concept of adding and subtracting integers. Help them see the why behind their answers using the interactive number line. The values change as individuals adjust the number line for each new...

Students add and subtract integers. For this algebra lesson, students add, subtract, multiply and divide integers. They apply the properties of numbers as they solve equations.

Young scholars explore the parts of an orange to develop an understanding of the addition and subtraction of fractions. The concept of representing parts of a whole by dividing an object into smaller pieces is experienced in this...

Practice addition, subtraction, multiplication, and division using tiles as manipulatives. In this math operations lesson plan, young learners choose the appropriate sized tiles, arrange them according to directions given by the teacher,...

Middle and high schoolers explore the concept of probability. In this probability lesson, learners conduct an experiment with a bag of marbles. Pupils draw marbles from a bag and determine the probability of drawing a particular color...

Students write equations for problems. In this number lesson, students add, subtract, multiply and divide numbers to solve for a variable. They rewrite word problems using algebraic symbols.

Sixth graders study addition and subtraction facts. In equal groups, they play a race game to correctly solve addition and subtraction problems. Using a PowerPoint presentation, the teacher demonstrates how to write word problems and...

Perform operations to add, subtract, multiply and divide matrices. Then solve problems with vectors using matrices. A three day lesson plan: Matrix Madness, Mystical Matrices, and Decode the Encode. The last lesson plan has prizes that...

Factor polynomials using electronic manipulatives. Your class will create a spreadsheet in excel and use it to multiply and perform basic operations and solve problems correctly. They create a visual to go along with each multiplication...

Working with imaginary numbers — this is where it gets complex! After exploring the graph of complex numbers, learners simplify them using addition, subtraction, and multiplication. 

Learn how to use a matrix to organize data to solve a problem. This activity uses wins and losses to rank players for an air hockey tournament they wish to have. After practicing some basic matrix operations the class could do the...

  Explore the connection between a finite graph, a directed graph, and a matrix. Graph lines and identify the relationship of matrices in real-world scenarios. Then use this information to work with a partner to plan and design a...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...
