Your learners will get lots of practice calculating simple and compound interest by the end of this lesson. Simple explanations and examples lead learners through the concepts and steps of calculating simple and compound interest...

Teach young mathematicians that sometimes just getting close to the exact answer is perfectly fine, by using this collection of estimation worksheets.

High schoolers evaluate functions graphically and algebraically. After completing that step, they write a statement describing the input and output.

Round and round we go. Learners first complete a task on writing equations of circles. They then take part in a collaborative activity categorizing a set of equations for circles based on the radius and center.

You won't want to flush a great lesson down the drain! An intriguing resource asks learners to predict the number of sheets of toilet paper on a roll. Presented with the dimensions of the roll and one sheet of paper, scholars make...

Few children's books convey the message of conservation as well as Dr. Seuss' The Lorax. Read the story aloud, emphasizing the interconnectedness of plants and animals in an ecosystem and discussing different ways people can help...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

Scholars learn how to write number theory proofs by viewing a video reviewing techniques for proofs on divisibility, parity, and consecutive integers. They then write proofs for a handful of conjectures on a worksheet.

Just how far can I see? The short assessment question uses the Pythagorean Theorem to find the distance to the horizon from a given altitude. Scholars use the relationship of a tangent segment and the radius of a circle to find the...

An equation is an equation is an equation. Scholars see there are many ways to solve them when they first sort a set of linear equations as written in standard form, point-slope form, or slope-intercept. They then write equations in all...

Challenge your classes to think between the curves. Given two function formed by the combination of two exponential functions, individuals must write three functions in which all values would lie between the given. The question is...

Students read picture books in which mathematics and solutions to math problems play a role in the action. After discussing the books and how the author used math problems to tell a story, they create their own magical, math-ical story...

Many scholars confuse velocity and acceleration even after they correctly solve basic problems. Using an interactive, part of a series on vectors and projectiles, with immediate feedback focuses their attention on the up or down...

The balance in an account continuously compounding interest is the context of this engaging task. Your young accountants will investigate the ending balance in an account as they compound the interest more and more. Learners write the...

Young scientists present their experimental designs from the previous experiment. The ninth lesson in the series outlines what learners should present, what class discussions should happen, and the solution NASA came up with for the same...

Investigate the relationship between independent and dependent variables. Individuals begin by identifying independent and dependent variables from different problem situations. Then, using specific guidelines, they create posters...

Just between us, this is a pretty cool lesson! Given two functions with the same slope, learners write three new functions whose outputs are all between the given functions. The question is open-ended, allowing pupils to explore the...

Take a unique approach to study the graphing of trigonometric functions. Young scholars consider two sine functions and write three functions that will lie between the two given. They use a graphing utility to assist in their explorations.

Learnersare given 26 tables and graphs in which they must fill in missing numbers and graph equations. They subtract a given value of x from a constant number, and use a number line to subtract larger numbers from smaller ones resulting...

Now you see them, now you don't! This fun peek-a-boo activity engages young mathematicians in developing their ability to compose and decompose numbers. After being presented with a series of counters, children close their eyes while the...

Drawing from a scenario of the history of the penny, learners write and solve a system of linear equations from a context.

Can utopia be achieved? Included here are three literature worksheets to pair with Lois Lowry's The Giver. Pupils work in groups to come up with solutions to society's issues, individuals back up a statement related to a topic in the...

What does completing the square have to do with circles? Math pupils use completing the square and other algebraic techniques to rewrite equations of circles in center-radius form. They then analyze equations of the form x^2 + y^2 + Ax +...

Look at rates from a general perspective. The 17th part of a 29-part series provides problems that help pupils develop more general ratios from given rates. Scholars determine unit rates and ratios that are associated with given rates....
