Here is a wonderful activity that allows young engineers to try their hand at designing a bridge out of spaghetti! The worksheet explains the activity and also provides a graph for keeping track of the results. Very good!

Read and research information on China. Young researchers complete a knowledge hunt about China then locate and describe each location using directional words. They recognize the word meaning through context clues and application practice.

In this comprehensive diagnostic test worksheet, learners examine, study, calculate and solve 38 math problems. They work with a variety of basic math concepts and word problems.

Students measure temperature and become aware the the temperature above and below the snow is different.  For this winter temperature lesson, students measure temperatures to find variation based on how the snow is packed. Students...

Elementary and middle schoolers explore the world of secret writing, otherwise known as cryptography. After an interesting introduction to the activity, learners utilize a decoder badge which uses the St. Cyr cipher - which is a cipher...

More than 80 percent of the earth's surface originated from volcanoes. The 16th lesson in a 20-part series introduces the shape and development of volcanoes. It begins with a demonstration using a balloon and flour to illustrate the...

Several times throughout history, groups of soldiers marching in rhythm across a suspension bridge have caused it to collapse. Scholars experiment with pendulums, resonance, and force to determine why this would happen. First, pupils...

How do you convert from one measurement to another? Pupils use unit rates to convert measurements from one unit to another in the 21st segment in a 29-part series. They convert within the same system to solve length, capacity,...

Does standard deviation work for non-symmetrical distributions, and what does it mean? Through the use of examples, high schoolers determine the standard deviation of a variety of distributions and interpret its...

Lesson 16 in the series of 28 is a mid-module assessment. Learners simplify expressions, write and solve equations, and write and solve inequalities. Most questions begin as word problems adding a critical thinking component to the...

What linear equation will fit this data, and how close is it? Through discussion and partner work, young mathematicians learn the procedure to determine a regression line in order to make predictions from the data. 

Learners examine objects and find their volumes using geometric formulas in the 21st installment of this 25-part module. Objects take the shape of truncated cones and pyramids, and individuals apply concepts of similar triangles to find...

Extend percent understandings to include percents less than one and greater than 100. A great lesson has pupils build upon their knowledge of percents from sixth grade. They convert between fractions, decimals, and percents that are less...

Math is a lot like building blocks—it requires a solid foundation. A short performance task has pupils consider the volume of a cubic block. It then asks mathematicians to find the surface area and volume of a prism made from stacking...
