Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...

Your learners will practice many ways of describing data using coordinate algebra in this unit written to address many Common Core State Standards. Simple examples of different ways to organize data are shared and then practice problems...

Counting is not all it adds up to be — sometimes it involves multiplying. The lesson introduces permutations and combinations as ways of counting, depending upon whether order is important. Pupils learn about factorials and the formulas...

When should you use a number line to add and subtract integers, and when should you use absolute values? Complete a set of worksheets designed to reinforce adding and subtracting integers with both standard problems and word problems....

English teachers around the world cringe when they come across fragments and run-ons in papers. A handout on these poor imitations of sentences helps bring relief by reviewing the basics of sentence construction and by offering...

Have your young writers speak their minds with a letter to the principal. Using a writing prompt at the top of the page, kids think about a change that they would like to see at their school. The prompt encourages them to consider...

Bystander or upstander and advocate? Three lessons have high schoolers investigating data about bullying and school safety. Participants then learn how to take a stand against bullying and use what they have learned to create a PSA to...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

Young readers discuss how they would deal with problems faced by the main character in Maniac Magee. They write down their own problems and exchange them with others to analyze and provide possible solutions. They establish a "Dear Abby"...

Get three planes to line up safely. Individuals work through a set of problems to eliminate spacing conflicts between three airplanes in flight. The pupils use their knowledge to change the airplanes' speed or route to meet a...

Monitor the growth of young mathematicians with a comprehensive addition and subtraction assessment. Using the context of a class field trip to an apple orchard, this series of four story problems allows children to demonstrate their...

Here is a fun project. Sammy observes a chipmunk and a squirrel to see how many holes each needs in order to stash the same number of acorns.  Scholars could find the answer algebraically or create a table to analyze the...

Problems come in all shapes and sizes, but the first step in solving a problem is to identify just what the problem is. Through a series of games and activities, middle schoolers learn first to identify a problem, decide on a solution,...

Changing ratios make for interesting problems. Pupils solve problems that involve ratios between two quantities that change. Groups use tape diagrams to represent and solve classroom exercises and share their solutions. 

Your Geometry learners will collaboratively prove that the tangent line of a circle is perpendicular to the radius of the circle. A deliberately sparse introduction allows for a variety of approaches to find a solution. 

Teach the connection between area models and the distributive property through problem-solving. The 22nd activity in a series of 29 explains the distributive property graphically. Learners build area models from word problems and convert...

Middle schoolers continue to study the problem solving process by identifying the pros and cons of different options they listed on their "How Could I Do This" activity sheet from the previous lesson. After weighing the options, they...

Try to find an estimate when the exact answer is not clear. Using the General Certificate of Secondary Education Math review resource, pupils learn how to find an estimate to a cubic equation. Class members use the trial-and-improvement...

Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...

Physics class has its ups and downs ... especially when it involves energy concepts! Scholars analyze information to determine changes in kinetic and potential energy using an interactive resource. Realistic scenarios make connecting...

How is religious freedom connected to the conflict between China and Tibet? After reading an online passage of background information, your learners will divide into groups and both read and view an interview with the Dalai Lama. They...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Learners sometimes have difficulty making sense of a word problem. In a guided learning activity, pupils are asked to think about how to find an answer and explain their thinking, rather than finding the answer. It allows them to...

In this third of a twelve-part series, the focus moves from using matrices to solving systems of equations with substitution and elimination, including more than two dimensions and variables in equations, and analyzing statistical data....
