Now that learners figured out how to solve for one variable, why not add another? The activity demonstrates, through examples, how to solve a linear system using graphing, substitution, and elimination.

What effect does changing a parameter have on the graph of a trigonometric function? Pupils use a Desmos applet to explore the general sine graph. They experiment changing different parameters and record the resulting change of the...

It's time to show what they know! An assessment review concludes a five-part series about linear functions. It covers all concepts featured throughout the unit, including linear equations, graphs, tables, and problem solving.

Pupils determine equations that match the graphs of transformations and the parent quadratic function. The resource requires class members to attend to precision and think abstractly.

The sole purpose of this interactive is to graph a function representing the distance of a car from a shoe store. Scholars use an interactive to graph such an absolute value function. They then answer a set of challenge questions...

Earth science super stars visit the National Earth Science Teachers Association's interactive website to glean information on the layers of the atmosphere. Data tables are provided for them to record what is collected. This assignment...

If any of the limiting factors in an environment change, both animal and plant populations also change. The video explains two different models of growth and the impact of limiting factors. It highlights the carrying capacity of an...

Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the...

New Horizons began its journey to Pluto in 2006. Ten years later, it continues its mission. In that time, scholars have surely grown, but how much more will they grow by the time New Horizons reaches its destination? Find out with an...

Use the age-old Traveling Salesman Problem to introduce Hamilton circuits to your young travelers. Individuals then plan an efficient route to visit all the places they want to go.

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

Surf's up, big kahunas! How do surfers know when the big waves will appear? They use science! Over the course of five days, dive in to the inner workings of tidal waves and learn to predict sea levels with the moon as your guide.

Explore parabolas in this algebra lesson with the graphing calculator. The class investigates what effects the changing of the parameters of the vertex form of a quadrati have to its graph. They find the zeros of a quadratic graphically...

Ready to apply the concepts related to the natural exponential equations and logarithmic equations? A math lesson reviews concepts from inverse properties to solving to derivatives and integrals. 

Everyone loves a vacation and a set of three activities has groups planning a tour of the U.K. using given distance, time, and price data. They solve a variety of problems related to the trip and produce a report on the success of...

Examine trends in student-to-teacher ratios over time. Building from the first task in the two-part series, classes now explore the pattern of student-to-teacher ratios using a non-linear function. After trying to connect the pattern to...

See how vertical and horizontal lines have special equations. Scholars drag vertical and horizontal lines onto a coordinate plane to graph given equations. They then answer a set of challenge questions on the topic.  

Make the most of your prom—with math! Pupils write and use a quadratic model to determine the optimal price of prom tickets. After determining the costs associated with the event, learners use a graph to analyze the break even point(s).

Young scholars discuss parachutes and write a procedure to determine the effect of different size parachutes and different masses on the time it takes the masses to fall. They record all their data from their experiment then write three...

Your learners will get plenty of practice solving quadratic equations in a worksheet using the quadratic formula. An extension to this activity would nicely connect MP5 concepts. Have learners use a graphing program to graph 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...

Stretch your teaching repertoire with an experiment on the elongation (stretching) and failure (break) of several materials. The point of the experiment is to design a composite material for chair webbing.
