Equivalent ratios show up on tape. Young mathematicians use tape diagrams to create equivalent ratios in the initial lesson on the topic. They learn the definition of equivalent ratios and use it to build others in the third segment of a...

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

Take a look at a star resource. Young mathematicians use a graphing calculator to draw intersecting lines that look like a star. They then apply translations to move the entire star and also consider what transformations must occur to...

Sorting memories doesn't have to be difficult. Young mathematicians evaluate two different methods of sorting yearbook pictures. They answer a set of questions to explore each method, then develop their own sorting procedure based on...

Grab the wheel in learning about functions. A short performance task challenges young mathematicians to develop a function that describes the cars eight people drive. They consider whether the inverse of the function exists. If not, they...

Jump at the chance to use parabolas. Young mathematicians apply trigonometry to explore the trajectory of a ball in different situations. Some walls cause the ball to bounce, so participants must consider all possibilities.

Root for young mathematicians learning about functions. A set of two problems assesses understanding of polynomial functions and their roots. Scholars select values for a, b, and c, and then create two functions that meet given...

Here's an interactive that will be a great match for math lesson plans. Young mathematicians use an interactive game to match fractions represented numerically and as fraction models. One game assesses fractions only, while the other...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

Mathematicians solve six multiple-choice and true or false questions using their knowledge of estimation and multiplying decimals. The interactive provides a garden-themed tool that creates a visual aid of three watering cans to assist...

A soccer-themed interactive challenges mathematicians to solve five questions involving percent equations. Question types include multiple-choice, fill in the blank, true or false and a discussion. A color-coded stadium with movable...

Young mathematicians can work these word problems to practice applying their two-digit multiplication and division to the 12s. Designed for use by learners in the UK, money problems are in denomination of pounds and pence, and cultural...

You class will read Cucumber Soup by Vickie Leigh Krudwig as an anticipatory set for this lesson on ratios. They make models of the insects in the story and then use them as a source of data for this ratio and proportion lesson. This...

A lengthy narrative about Pythagoras and his students precedes an activity in which your young mathematicians practice using the Pythagorean theorem to solve three problems about flight and distance. Answers are provided. 

Get your little mathematicians moving with this experiential activity in which one child is the "tens" and another is the "ones." They collect the number of unifix cubes (in tens or singles) assigned to their respective place values and...

Young mathematicians review fact families and create a Math Fact Family Tree. This clever lesson plan includes some excellent printouts that support the lesson.

This simple lesson has young mathematicians consider all of the expenses, and monetary rewards a typical lobsterman encounters when going about his business. Given a few pieces of information, pupils must figure out a lobsterman will...

Young mathematicians apply problem-solving skills to equations that have more than one variable. They will work through the process to problem solve and discover the solution.

Young mathematicians are presented three possible graphs to represent the number of students who have a given number of pockets in their clothes. They must choose the most appropriate graph and write out short explanations regarding...

Mathematicians participate in an hands-on activity to investigate the binary number system and write messages in binary code and have classmates decipher the messages. A said video on the topic does not seem to be available, but the...

Add imagination and creativity to your math lesson. Young mathematicians investigate ways to express their names in mathematical terms. For instance, they can count the number of letters, analyze the geometric shapes of the letters, or...

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Young mathematicians examine the "Tic-tac-toe" factoring method to factor polynomials. They use algebra tiles to model solutions of binomial multiplication problems. They discuss strategies and observe teacher-made models for solving...

Young mathematicians read the book, The Doorbell Rang. They examine the necessity of division in everyday life, such as cooking and sharing. They use paper cookies to construct equivalent sets.
