If you think Dr. Seuss has no place in a math classroom, then take a look at this resource. Based on the classic children's book Green Eggs and Ham, this sequence of activities engages children learning to model real-world contexts...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Build on your class' understanding of real numbers as they begin working with complex numbers. Pupils begin with an exploration of i and the patterns in the powers of i. After developing a definition for i, they simplify complex number...

Who knew determining author's purpose could be turned into a game? Four teams compete to correctly identify the author's purpose for writing a series of passages.

Looking for a way to challenge the problem-solving abilities of your young mathematicians? Then look no further. This collect of newsletter worksheets engages learners with a variety of interesting word problems that cover topics ranging...

Pie isn't just for eating! Scholars learn to create pie charts and circle graphs to represent data. Given raw data, learners determine the percent of the whole for each category and then figure out the degree of the circle that percent...

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Processed foods use inorganic compounds for flavoring and preservation. This take-home laboratory challenges scholars to find 20 different compounds identified on the labels of foods to list on their data collection sheet. The activity...

How long do we have to wait? Given several days of times between eruptions of Old Faithful, learners create a graphical representation for two days. Groups combine their data to determine an appropriate wait time between eruptions.
