The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

What influences the way you dress, or celebrate holidays, or connect with your friends? Explore the cultural traits that are not easily seen with an engaging discussion. Using the model of an iceberg, learners place features of culture...

As part of an investigation of transformations of exponential functions, class members use Newton's Law of Cooling as an exponential model to determine temperature based on varying aspects. The resource makes comparisons between...

Use context to explain the importance of the key features of a graph. When context is introduced, the domain and range have meaning, which enhances understanding. Pupils use application questions to explore the key features of the graph...

Our young scientists have now specifically identified a problem, and this step helps them think of possible solutions. An outline, including guidelines, for brainstorming helps scholars stay on the right path. The resource includes...

Get siblings to do your work. Scholars learn how to perform summations of arithmetic sequences in an innovative lesson. They use iterations, smaller siblings (tail-end recursion), and the divide-and-conquer approach.

Connect linear equations, proportionality, and constant rates of change to linear functions. Young mathematicians learn how linear equations of the form y = mx + b can represent linear functions. They then explore examples of linear...

Explore the power of mathematics through this two-week statistics unit. Pupils learn about several climate-related issues and complete surveys that communicate their perceptions. They graph both univariate and bivariate data and use...

What percentage of your class understands percents? Pupils learn the meaning of percents based upon rates per 100 in the 24th instructional activity in a series of 29. They represent percents as fractions, decimals, ratios, and models....

Find out the characteristics that makes a bug an insect with a workbook designed to inform scholars about the crawly creatures that live around us. Scholars complete an ant-themed word search, answer questions using a solution key,...

Equivalent ratios show up on tape. Young mathematicians use tape diagrams to create equivalent ratios in the initial lesson on the topic. They learn the definition of equivalent ratios and use it to build others in the third segment of a...

Ratios may not be created equal, but they are equivalent. Pupils learn the theorem relating equivalent ratios and equal values in the eighth segment in a series of 29. Classmates use the theorem to determine whether ratios within...

Scholars learn to order rational numbers in the seventh lesson in a series of 21. Reasoning about numbers on a number line allows for this ordering.

Do you want to use the resource? Absolutely. Scholars learn about absolute value and its relation to magnitude and distance on a number line. They compare numbers in context by applying absolute value. 

Go on a weed hunt! Scholars gain insight into the characteristics of plants and examine the outdoor environment in order to identify five different types of weeds. Learners then show what they know with a one-page reflection.

Become a pest detective! Individually or in small groups, scholars scout the land to discover which pests—plant and animal—inhabit it, determine whether the pests are endangering the environment, and summarize their findings.

Create ratios using the boys and girls in the class. The first lesson in a 29-part series introduces ratios. Pupils learn to create ratios, write them, and model them with tape diagrams. Class members realize that there are different...

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Reinforce the concept of one-to-one correspondence with a Valentine's Day-themed counting and color sorting activity. Scholars sort foam hearts by color—red, orange, yellow, green, blue, and purple—then count and place them on a number...

Prescription drugs may start out with legitimate usage, but lately they are finding their way to high school and college party life. Have a discussion with the teenagers in your class on prescription drug abuse with a PowerPoint...
