Let's give parameters a second try. Scholars take a second look at a system of linear equations that involve a parameter. Using their knowledge of solutions of systems of linear equations, learners describe the solution to the system as...

Chase the traveling solution. Pupils analyze the solutions to a system of linear equations as the parameter in one equation changes. Scholars then use graphs to illustrate their analyses.

Find the area as it slides. Pupils derive an equation to find the painted area of a section of a trapezoidal-shaped stage The section depends upon the sliding distance the edge of the painted section is from a vertex of the trapezoid....

Up the difficulty level by solving a system of equations with variable coefficients. Young scholars devise a plan to solve for x and y in terms of a and b. They represent their solutions as expressions and explain their...

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

The slope makes a difference. Given an equation of a circle and point, scholars determine the relationship of the slope of a line through the point and the number of intersections with the circle. After graphing the relationship, pupils...

Strive for gold with an informative resource. A short task challenges learners to investigate the thickness of a box made from a given volume of gold. The box must have specific dimensions, so setting up and solving a literal equation is...

What if a coordinate plane becomes a slope-intercept plane? What does the graph of a linear function look like? Learners explore these questions by graphing the y-intercept of a linear equation as a function of its slope. The result is a...

Round and round and round we go. Given a diagram of three circles, two of which share a point with the third circle, learners identify the radius of each circle. Doing so requires setting up and solving a system of equations based on the...

Find the function that fits. Scholars first identify the graph of a function that looks the same after a horizontal translation. They must then find the equation of a function whose graph lies only in two adjacent quadrants.

In this balancing chemical reactions worksheet, students fill in the proper coefficients in front of the reactants and products of 20 equations to balance each given chemical equation.

In this balancing chemical equations worksheet, students solve 10 problems. They complete the reactions, name the type of reaction such as synthesis, decomposition, or single replacement and then balance the equation.

Pupils solve chemical equations. For this chemistry lesson, they balance chemical equations after completing a lab. They can use a TI for this assignment.

In this redox reaction worksheet, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.

Balancing equations is a foundational skill for starting chemists. There are a few slides in this PowerPoint with colorful diagrams that help to explain how. Unfortunately, the presentation begins with an unrelated table of contents and...

In this thermodynamics worksheet, students predict the change in reaction values for the 14 thermodynamic reactions given.
