Middle and high schoolers explore the concept of proving the Pythagorean Theorem. They research proofs of the Pythagorean Theorem. Pupils create posters of proofs, and research Greek mathematicians.

With this interactive lesson, learners compute the surface area of rectangular prisms. They visit an online investigation applet and record data on the provided handout. Pair this lesson with the volume lesson by the same publisher as an...

Explore the concept of volume of prisms using an applet to perform the calculations. The link to the interactive applet is embedded into the lesson plan as well as a link to associated data sheets. Get your math class to the computer lab...

Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Students review how to solve problems using the Distributive Property of Mathematics. They solve problems using the paper and pencil method and then use the graphing calculator to discover the property over addition while making a visual...

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

What does it take to build a stable arch? Pupils apply vectors and physics as they examine arched bridges and their structural integrity. They use vectors to represent the forces acting on the stone sections and make conclusions based on...

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...

Students solve problems using the distributive property. In this algebra lesson, students solve equations by multiplication and combining like terms. They graph their lines on the calculator.

Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate...

Young scientists explore Earth elements by conducting an experiment. They define water vocabulary terms such as condensation and precipitation. In addition, they conduct a water experiment in which they build a terrarium, so they can...

Young scholars solve problems by adding.  In this collection of addition lessons, students answer a variety of word problems and utilize addition skills. Links provide access to definitions and sample problems. 

Don't stop with two-dimensional learning, go to the next dimension! Learners verify that 3x3 matrices represent linear transformations in the third dimension. Additionally, they verify the algebraic properties that extend to vector...

Show your math class how to use vectors in adding complex numbers. Vectors represent complex numbers as opposed to points in the coordinate plane. The class uses the geometric representation to add and subtract complex numbers and...

Second graders are introduced to different types of motion. They make rolling spider toys and race them on different surfaces to invsetigate forces and motion. Pupils make glue "spider webs" for their spiders after testing different...

Students explore the concept of addition as used in the subject of Algebra while reviewing the different methods using a number line. The lesson includes examples for students to use for scaffolding for group work or whole class...

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...

Learning how numbers are put together as parts and wholes is a big step in building the foundational number sense of young mathematicians. Here, children are given a number less than 10 and are asked to find as many pairs of numbers as...

Second graders participate in Math-Eze activities to comprehend word problems. In this word problem lesson, 2nd graders recognize why a hexagon is the best shape for a beehive. Students calculate how far bees must travel to find 2 lbs....

Learners amaze their friends and families with this human calculator trick. In this algebraic lesson, students use the associative property of addition to act as a human calculator and stump their volunteers. The steps to the trick,...

Second graders examine the commutative property of addition and the property of zero in addition and subtraction. They complete an asessment worksheet to gain practice reading and working number sentences horizontally and vertically.

First graders practice modeling addition. In this hands-on addition lesson plan, 1st graders are introduced to the Commutative Property of Addition and the Zero Property of Addition through modeling and the use of manipulatives. This...

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 the ins and outs of matrix multiplication. After discovering the commutative property does not apply to matrix multiplication in a previous lesson in the series, pupils now test the associative and distributive properties. The...
