Seventh graders identify rational and irrational numbers and then, estimate the square root of numbers that are not perfect squares. They then identify what the radical is and differentiate between that and a division symbol clearly....

Fifth graders model and distinguish between prime and composite numbers. Students are paired up with another classmate to complete this lesson. Students are assigned different numbers to work with, they use square tiles to form as many...

In this complex number worksheet, students explore the properties of imaginary numbers to find the square roots of negative numbers. Explanations and examples are given prior to the exercise. This two-page worksheet contains ten problems.

Students explore parts of a whole. In this fraction lesson plan, students determine what makes a fair share. Working with manipulatives, students solve mathematical problems containing fractions.

Explore the concept of this perfect square trinomial and difference of squares instructional activity. A hands-on activity that uses paper rectangles and squares to illustrate the perfect-square trinomial and difference of squares formulas.

Discuss different techniques for finding the area of a geometric shape, with a great visual guide. Using a real life example, learners calculate the area of a rectangle and a square. 

Use the multiplication table as an aid for young mathematicians who are learning their multiplication facts. Children can explore the concept of multiplication by using the factors in the far left column and the top row to determine a...

Sort this resource into the Use pile. Scholars investigate attributes of quadrilaterals and then use the results to sort and classify the shapes labeling each figure with their properties to justify the classifications.

Functions behaving badly: the squaring function and the absolute value function are both zero at x=0. Yet when you divide each by x, different things happen. Here, your class will explore each scenario as a means to adding depth to their...

Create rectangles from the terms of a trinomial. The interactive provides virtual algebra tiles for participants to use to create quadratic trinomials. Pupils use the tiles and arrange them into a rectangle to find the factors of the...

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

Working individually and collaboratively, geometers gain a clear understanding of the Pythagorean theorem. They create, explain, and compare proofs of the theorem. Proofs involve areas of trapezoids, squares, and triangles, congruent...

Students use numbers as descriptors. In this mathematical inquiry lesson plan, students use numbers to describe, classify, and compare plants. Students are made aware that numbers can be used to describe things in the world around them.

Students explore Google search engine in and out of China, examine events surrounding confrontation at Tiananmen Square between Chinese forces and the Tank Man, and discuss how censorship affects what the media reports and what the...

In this division worksheet, students figure out which shapes represent which single digit number in a long division problem. Students then answer 3 questions.

Eighth graders explore prime and composite numbers. Given division problems, they use color tiles to model solutions to division problems. Through activities and observation, 8th graders discover the meaning of prime and composite...

Learners multiply decimals and/or mixed numbers. They explore the effects of multiplying decimals and mixed numbers. They practice estimating answers when a number is multiplied by a decimal or mixed number.

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

Explore skip counting by twos with young mathematicians as they complete these engaging activities. First, they color in squares to represent counting by twos in an even sequence and an odd sequence. Next, they connect dots (by twos) to...

What do you do when factoring doesn't work? Learners complete the square when faced with quadratic expression that don't factor traditionally. They then use factoring by grouping to solve polynomial equations.

Middle schoolers build a three-dimensional 12-pointed star as a geometric exercise. The shape is quite-difficult to construct. Luckily there is an excellent template that learners cut out, then use to make their pyramid. The second part...

Faster than a speedy calculator! Show your classes how to use polynomial identities to multiply numbers quickly using mental math.
