How can people use simple machines to solve real-world STEM problems? Learn about simple machines using a hands-on, project-based learning activity. First, pupils investigate and evaluate simple machines. Then, they receive a task that...

For this solutions worksheet, students review how molarity is calculated and how to prepare a dilute solution. This worksheet has 5 problems to solve.

In this electrochemistry worksheet, students balance 10 chemical equations and complete 28 additional questions about electrochemical cells.

Students use unfamiliar objects to make inferences. In this making inferences lesson plan, students make guesses about what an item does. Students brainstorm together and make lists of ideas and write them on index cards. The teacher...

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....

Squares can be magic. Pupils use their knowledge of addition of positive and negative rational numbers to create a 3 X 3 magic square where the sums are 1. Scholars create addition and multiplication expressions with a set of rational...

This first of twelve algebra 2 resources provides a broad review of many algebra 1 concepts through a number of separable lessons and labs. Starting with the real number system and its subsystems, the sections quickly but thoroughly...

Young readers use graphic organizers, such as Venn diagrams and story maps, to analyze a variety of folktales and the elements of a story. They use writing, sequencing activities, and creative art to identify the morals learned from a...

Learning how a bank account works is a useful tool. The exercise in the resource is to deduct rent from a checking account and create an equation from a description. Participants then graph the balance of the bank account versus months...

A new, improved version of the game Battleship? Learners graph linear inequalities on the coordinate plane, then participate in a game where they have to guess coordinate points based on the solution to a system of linear...

Polynomials are full of solutions! Learners understand that the degree determines the number of solutions. Examples show quadratic equations solved by factoring and by using the quadratic formula. A cubic equation is even mixed in for...

Zero in on your pupils' understanding of solving quadratic equations. Spend time developing the purpose of the zero product property so that young mathematicians understand why the equations should be set equal to zero and how that...

Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...

Fill-out a story map to help your scholars with pre-writing. They will use a story map template to pre-write. They also organize their ideas into steps which become the foundation for their first draft. Concrete objects are brought in to...

Your young gossipers write an exponential function for the number of people who have heard a rumor after a number of days have passed. Learners then answer a series of questions, including whether or not the solutions are realistic by...

A basic set-up leads to a surprisingly complex analysis in this variation on the question of surrounding a central circle with a ring of touching circles. Useful for putting trigonometric functions in a physical context, as well as...

Drive or take the school bus? Class members determine the amount each student would have to pay in a carpool situation. They then evaluate  the cost in a set of provided examples. I think I'd rather take the school...

Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Creative activities help bring literature alive. The first of a set of lessons designed to accompany selections from Theme 4: Problem Solvers uses activities such as skits, responses to music, and social studies projects. These...

Taxi! Have your travelers figure out how far they can go in a taxi for $10.00. They must account for the mileage rate and tip in their calculation. They can set up a table or make an equation to solve for the exact mileage they can...

Your algebra learners build a quadratic function in this task of counting the blocks used to build objects. The arithmetic sequence that shows up brings up a shortcut to the long addition using the Gauss Method. Eventually, learners...

Your young microbiologists will interpret and solve exponential equations in this real-world context task set in a hospital research scenario. Learners think in terms of the functions as well as their rates of change.
