Students compare, classify and calculate the area of geometric figures such as rectangles, squares, circles and triangles.

Tenth graders role-play as members of the food chain. Sticky tables acting as polluting factors are introduced and members of different trophic levels suffer varying degrees of damage due to those pollutants.

Young scholars create wall hangings from fresh flowers using a technique called flower pounding. Wall hangings can be used to create a classroom quilt as well. This is an activity that can be adapted for many grade levels.

Students write a descriptive essay.  In this Holocaust instructional activity, students discuss what it must have been like for Anne Frank to stay inside for two years.  Students try to appeal to all five senses in their...

Eighth graders examine the physical properties of different minerals. In this earth science lesson, 8th graders explain the uses of minerals in their daily lives. They complete the mineral identification table during the lesson.

Discrete or not discrete? Individuals learn about the difference between discrete and non-discrete functions in the fourth installment of a 12-part module. They classify some examples of functions as being either discrete or non-discrete.

Formalize the notion of a function. Scholars continue their exploration of functions in the second lesson of the module. They consider functions as input-output machines and develop function rules for selected functions.

Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...

The 19th installment in a 25-part series builds upon the sampling from the previous unit and takes a larger sample. Pupils compare the dot plots of sample means using two different sample sizes to find which one has the better variability.

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...

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...

Pupils work several real-world problems that use percents in the 11th portion of a 20-part series. The problems contain percents involved with taxes, commissions, discounts, tips, fees, and interest. Scholars use the equations formed for...

Which rate is greater and by how much? Pupils continue to compare rates to solve problems in the 20th portion of a 29-part series. Rates are presented in a variety of representations either using the same representation or different...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Explore using units with scientific notation to communicate numbers effectively. Individuals choose appropriate units to express numbers in a real-life situation. In this 13th lesson of 15, participants convert numbers in scientific...

Scholars investigate the spread of associated data sets by comparing the data sets to determine which has a greater variability. Individuals then interpret the mean as the typical value based upon the variability.

Learners graph and order numbers using a number line. They also solve word problems using fractions and decimals and rewrite equations to solve problems correctly. Several example word problems are given. 

Go down the rabbit hole with a thorough novel unit for Lewis Carroll's Alice in Wonderland. With a cause and effect chart, K-W-L organizer, and reading comprehension questions, the resource is a great addition to your summer...

Time for statistics and learning to overlap! Learners examine Venn Diagrams as a means to organize data. They then use the diagrams to calculate simple and compound probabilities.

Discover an important property of linear functions. Learners use the slope formula to calculate the rates of change of linear functions. They find that linear functions have constant rates of change and use this property to determine if...

Ask class members to reflect on their year-long writing experience by creating a portfolio of their work. Here's a resource that details what should be included in such a portfolio, and provides a rubric that can be used to assess...

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

Calculate theoretical probabilities and compare them to experimental probabilities. Pupils build on their knowledge of experimental probabilities to determine theoretical probabilities. Participants work several problems with the...

Class members solve problems to find the whole when given a percent. They  use double line numbers and factors of hundred to help break the 100 percent into equal segments.
