Young geometers become pool sharks in this analysis of the angles and lengths of a trick shot. By using angles of incidence and reflection to develop similar triangles, learners plan the exact placement of balls to make the shot....

Students read a short novel while filling in a graphic organizer for problem and solution.  In this sociology lesson, students use a prior knowledge and relate the text to theirselves and to think about their own...

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Packing for a trip? This activity allows learners to decide how many magazines and protein bars they can buy with twenty dollars. They can organize their work in a chart to track how many items they can purchase. There are two different...

What if you had a design problem you wanted to solve, but were unable to draw because you were unable to see? Teach your learners with visual impairments that they can use Wikki Stix®, a braille ruler, Legos®, and Constructo Straws to...

Triangle centers and the segments that create them easily become an exercise in memorization, without the help of engaging applications like this lesson. Here the class investigates the measure of center that is equidistant to the three...

Teach solving for unknowns through a problem-solving approach. The grouping of five lessons progresses from finding an unknown through simple reasoning to solving simultaneous equations involving three and four variables. Each lesson...

Puzzle your way through to a new understanding of area. Scholars learn about the area of polygons through equidecomposability, the idea that polygons that can be decomposed into the same set of pieces have the same area. By using...

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Science, technology, and math come together in this one combination exercise. Analyzing the common soda can from both a purely mathematical perspective and a scientific angle allows for a surprisingly sophisticated comparison of...

Learners separate things that just appear similar from those that are actually similar. A diagram of triangles is given, and then a variety of geometric characteristics changed and the similarity of the triangles analyzed. Because the...

The penny arcade gets the statistics treatment in this fun probability investigation. A non-standard game of chance is described and then the class is set loose to find missing probabilities, determine common outcomes, and evaluate...

How can you find the solution to an addition or subtraction problem by guessing? Practice the guess-and-check strategy with a fun math activity based on Ms. Squid's ink mess on the homework. Kids determine which number is covered by the...

One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...

Make the connection between Hooke's law and elasticity with an activity that introduces the class to the behavior of elastic materials. The resource defines stress and strain to calculate the modules of elasticity of...

Without ever using the actual term, this exercise has the learner develop the key properties of the midsegment of a triangle. This task leads the class to discover a proof of similar triangles using the properties of parallel...

Teach your class about colony collapse disorder and foster discussion about causes and solutions for the honeybee problem. Class members read and discuss an article and participate in one of two detailed activities about pollination and...

Reinforce multiplication strategies with a instructional activity that examines a word problem and the distributive property. Mathematicians work collaboratively to solve the problem, create a poster with their solution, and share their...

Learners make predictions and draw conclusions from given information as they learn the meaning of probability in this vocabulary-rich, integrated activity that presents a variety of teaching strategies to motivate and reach...

In this math worksheet, students complete addition word problems with short answers and multiple choice place value problems. Students complete 42 problems total.

Fifth graders use a software program to practice their problem solving skills. As a class, they identify patterns in their days at school and review problem solving patterns in math. They solve different problems and discover that the...

Encourage your young citizens to make a difference. Using Tyson Miller's Dream of a Nation: Inspiring Ideas for a Better America as a starting point, class members watch documentaries, investigate issues, and then write letters to...

What media literacy skills do people need to evaluate a news source? Scholars listen to and discuss an NPR story about how fake headlines often dupe young people and adults alike. Next, they study news stories, using a fact-checking...

Just like you choose your clothes to ensure they fit the occasion, you should choose your words deliberately while writing. Style, the main topic of one handout in a series on writing skills, involves choosing words carefully and paying...
