The task is simple, but the solution is a little more complex. Learners must find the smallest number that results in a perfect square when multiplied by two and a perfect cube when multiplied by three. The task requires an analysis...

Explore the process of simplifying square roots through an analysis of perfect squares. The fourth lesson of 25 expects individuals to find the perfect square factors in each radicand as a means of simplifying. The perfect square factor...

Square away any doubts about using a new resource. Pupils learn about squares and square roots in the mini-activity. They complete a worksheet identifying roots of perfect squares up to 400.

Think outside the box and use an engaging, interactive app that shows the relationship between square roots and squares using an actual square. Pupils find that moving a slider increases the side length of a square and its associated area.

Teach cube roots by building on an understanding of square roots. The third installment of a 25-part series asks learners to solve simple quadratic and cubic equations using roots. Scholars compare square roots and cube roots throughout...

Class members explore the estimation of irrational numbers in association with the Pythagorean Theorem. The first instructional activity of this module challenges pupils to use the Pythagorean Theorem to find unknown side lengths. When...

You mean the square root of five and five don't have the same value? Learners estimate the value of irrational roots. As they practice estimating the value, they increase their understanding of roots. The lesson is the fourth in a series...

Residual plots let you find the perfect line of best fit. As users adjust the points on a scatter plot and a possible line of best fit, the interactive automatically changes the residual plot. This change allows them to see connections...

A neat and organized formula handout makes the circle go round, doesn't it? Full of higher algebra topics, formulas and rules, graphs and definitions—there is a way to support everyone in Algebra II or Pre-Calculus. 

Now that the practice is over, see if young mathematicians can utilize their new skills on finding common denominators and adding fractions. The assessment contains one map challenge and follows with skills practice. 

Take a break from reading to find the magic number with this vocabulary game using words drawn from Jerry Spinelli's Maniac Magee.  Participants match the definition to the word in each numbered square of the puzzle, then add...

Investigate the meaning of the Pythagorean Theorem through modeling. After comparing the area of the square of each side, individuals cut triangles and squares to facilitate the comparison.

If you've always wanted to know more about spreadsheets, here's a perfect resource for you. A self-paced tutorial introduces how to autofill and copy formulas in a Google sheet or Excel spreadsheet. It also shows users how to find range,...

Who was Lorenzo de Zavala to the Texas Revolution, and how did he change the Alamo? Find out using an educational resource that asks learners to fill out graphic organizers and respond to short-answer questions to further solidify their...

What is the connection between the quadratic formula and the types of solutions of a quadratic equation? Guide young mathematicians through this discovery as they use the discriminant to determine the number and types of solutions,...

Polynomial multiplication and factoring go hand in hand. Why not teach them together. This resource begins with an area model for distributing a monomial and then connects the process to factoring the GCF. Learners then advance to...

Enjoy these straightforward and simple worksheet pages that practice with different denominators. The practice starts simple with adding fractions together and then works on a recipe that needs to be tripled. 

Help young mathematicians build a solid understanding of division with this base ten block activity. With the help of these popular math manipulatives, children model different math problems in order to reinforce the...

Shapes are everywhere in the world around us, from rectangular doors to the circular wheels of a car. The second lesson in this series opens the eyes of young mathematicians to this wonderful world of shapes as they search the classroom,...

Find special products (perfect squares and difference of squares) of 'advanced' binomials: binomials with leading coefficients other than 1; binomials with higher degrees; and binomials with two variables.

Practice finding the approximate value of square roots by thinking about perfect squares. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video, or receive hints.

Resource provides review and practice of how to find the square root of perfect squares.

This task develops students' number sense of squares and square roots. They are to find an approximation of a less obvious square root of a number to see where it would fall on a number line. To do this, they must examine perfect squares...
