Teaching expanded notation is a great way to enhance young mathematicians' understanding of place value. This presentation explicitly describes the process, starting with the largest place value and working down, from left to right,...

Learning how to regroup when subtracting numbers can be challenging and requires a solid understanding of place value. Walk your class through the steps with a clear and explicit presentation that addresses standard regrouping and...

What does baking cupcakes have to do with multiplication? Watch this video and find out as your class learns that multiplication is the repeated addition of equal groups. Properties of multiplication are also introduced with...

Please excuse my dear Aunt Sally! Sort of like an animated slide show, this lesson walks fifth graders through the order of operations. Also included are a sing-along karaoke video, key vocabulary with definitions, and a seven-question...

First graders learn the basic needs of plants and identify geometric shapes while planting a fall garden. Combining math and science in one lesson plan, the resource guides kids through starting their class garden as they...

You aced the first test, so your score on the second one shouldn't matter, right? Young pupils first draw a best fit line on a provided scatter plot showing test scores for two different tests. They then evaluate five...

Looking for a way to assess pupils' personal financial literacy? A 100-question, multiple-choice exam provides a good understanding of what class members already know and need to know about personal finance. 

Future statisticians and potential psychics first conduct an experiment to collect data on whether a person can tell if someone is staring at them. Statistical methods, such as hypothesis testing, chi-square tests, binomial tests, and...

True or false — Double Stuf Oreos always contain twice as much cream as regular Oreos. Scholars first measure the masses of the filling in regular Oreos and Double Stuf Oreos to generate a class set of data. They use hypothesis testing...

Math language? Set notation is used in mathematics to communicate a process and that the same process can be represented as computer code. The concept to the loop in computer code models the approach pupils take when creating a solution...

Written to assess students' knowledge of interpreting expressions that represent a quantity in terms of its context, this machine-scored task also allows for a good discussion about units guiding the problem solving and solution.

One of the most common, everyday applications of math is dealing with money. This single problem calculating how much change Margie receives is more involved than it appears at first glance. An understanding of how fractions and decimals...

One of the hardest skills for many young geometers to grasp is to move beyond just declaring obvious things true, and really returning to fundamental principles for proof. This brief exercise stretches those proving muscles as the...

As an assessment task, learners must determine the radius of a new tank that has double the capacity of a given tank. Task tests knowledge of determining volumes of cylinders and spheres.

A variety of word problems help your learners examine the ways that they find solutions. Each question provides opportunities to add, subtract, and multiply time, measurements, and money.

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...

Here is a resource where algebra learners show their understanding of a system of equations involving a circle and a line. Once graphed, learners see two points of intersection, one where the ordered pair is read, and a second where...

The validity of data depends on the strength of the sample. A collection of instruction and activities focuses on sampling distributions and the analysis of that data. Scholars learn about distribution tests such and Central Limit...

Here is a well-designed resource that provides five yes-or-no questions which model different situations with linear functions. It makes a good pre-test for the beginning of the unit. The purpose is to elicit common misconceptions of...

The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

After watching a brief video on addition and subtraction, young mathematicians are put to the test. Including 12 problems, individuals solve word problems to find the least number, total amount, and difference of numbers. 

As a middle school assessment task, learners interpret the graph of distance versus time for a bike ride. Pupils then determine distance of the trip, length of the trip, and speeds.

Take a closer look at continuous functions within given intervals. Using the parent cubic function, learners explore properties of continuous functions on intervals. Pupils interpret the Intermediate Value Theorem and the Extreme Value...

Airline mechanics must be precise, or the consequences could be deadly. Their target ranges alter with changes in temperature and pressure. When preparing an airplane for flight, you must read a maintenance graph. The second lesson of...
