Painting a fence can be useful for more than just making your yard look good. A slider interactive has young mathematicians adjust the number of white fence panels. This activity helps in understanding how absolute value equations...

Create polynomials with specific values. The task consists of writing three polynomial functions that evaluate to specific values for any given number. Scholars first find a polynomial that evaluates to one for a given value, then a...

Pupils use visual models, numeric methods, and equations to solve percent problems. To complete the second installment of 20, they find the part given the percent and the whole, find the percent given the part and the whole, and find the...

Positive and negative numbers are all around us. Groups read short story contexts and identify a rational number that represents the values in the context. They order the rational numbers and interpret statements of inequality.

There are 3 problems on this page, in which learners must compose the given number in both expanded and standard form. They are shown images of blocks representing hundreds, tens, and units, they write the number of hundreds, tens, and...

Young mathematicians spin their way to a deeper number sense with this fun, collaborative activity. Using two spinners, one with the numbers 0-9 and the other with the decades 00-90, pairs of learners take turns building and comparing...

Your car decreases in value from $20,000 to $17,000. What percent of the value have you lost? Pupils answer word problems by determining the percent of change. 

Your students are obviously clever, but now they can be C-L-E-V-E-R! Enhance a research project with an exercise that prompts learners to identify the creator, location, era, and value of the information source, as well as provide an...

Go! Slow! Whoa! As part of a study of the nutritional value of foods available on the school campus, groups label those that are fine anytime as "Go" foods. Those that are okay a few times a week get the "Slow" label while those...

Discuss the lives of the children of East Asia using this resource. Learners read an article about children's values, aspirations, and expectations in East Asia. Students match ten vocabulary words to their correct definition and write a...

Developing fluency with basic addition and subtraction is fundamental to the success of all young mathematicians. This four-day lesson series begins with learners using ten-frames and hundreds charts to recognize patterns when adding and...

Estimating the value of numbers is much harder than it sounds! Scholars compare and order the value of numbers presented in different forms including fractions, decimals, roots, integers, and pi. This builds on the previous lessons in...

class members first work through finding the equation, table of values, graph, and key features of a linear function expressed verbally. Individuals then work through several more problems given different representations.

So the mean is not always the best center? By working through this exploratory activity, the class comes to realize that depending upon the shape of a distribution, different centers should be chosen. Learners continue to explore...

Build on your classes' understanding of irrational numbers by comparing their values. The 13th lesson in the 25-part module has individuals estimate values of both perfect and non-perfect roots. They finish by graphing these numbers on a...

Why do artists create? To solve a problem, of course. Young artists work individually and then in groups to create observational, imaginative, and narrative drawings in response to an assignment that requires them to employ all 16...

You know 4 + 4 + 4 = 3(4), but what about x + x + x? Pairs work together to develop equivalent expressions relating multiplication and addition in the third lesson of a 36-part series. They extend their knowledge of multiplication as...

Your business executives choose which of three equivalent forms of a quadratic equation is the most useful for finding various pieces of information in this task centered on a company's profits.

Your Algebra learners analyze and solve an exponential equation in this popular, real-life model of the cooling of a liquid.  

What does an ad reveal about a culture, or about the values of its intended audience? Class members examine a series of runaway slave ads—one of which was written by Thomas Jefferson—and consider what these primary source documents...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

So many things to remember when graphing polynomials and this guide gives a helping hand to do so. The packet goes through examples and explains things like critical values, end behavior, and multiplicities. There are image links and...

Measuring the diameter of the sun may get a little heated, but using an indirect approach can help individuals keep their cool. Learners use the reflection of the sun to measure how long it takes for it to move one diameter. Using the...

What's my number? Spark mathematical thinking and have some fun with thirty number puzzles that pose a series of questions to guide learners towards number discovery.
