Is containing a conflict possible in the Horn of Africa? Young peacekeepers engage in a simulation that examines the multi-faceted conflict that exists between the countries of Ethiopia and Eritrea. Representatives from ten countries in...

A short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.

Future mathematicians use an interactive to see how changing the size of a basketball court and the size of a region in the court affects the probability that a ball will randomly fall within the specified region. No calculations are...

Hands-on investigation of Riemann sums becomes possible without intensive arithmetic gymnastics with this interactive lesson plan. Learners manipulate online graphing tools to develop and test theories about right, left, and...

Andrew Carnegie's "The Gospel of Wealth" provides high schoolers an opportunity to engage more complex text. After a close reading of the essay and an analysis of Carnegie's argument that the rich are superior because they earn money,...

Fourth graders use pattern blocks to explore areas of polygons. They explain that the answers to the area of the same polygon vary according to the units of measurement used. They visualize how different units of measurement can be used...

Students examine unfamiliar units of measure. They practice converting equations to fractions and converting one unit of measurement to another. They work together to solve equations.

In this unit conversion activity, students solve 4 problems given a list of conversion factors for units of energy, power and flux.

In this Algebra I/Algebra II learning exercise, students solve verbal problems in which they calculate rates using the appropriate unit of measure.  The one page learning exercise contains a combination of seven multiple choice and...

In this metric units of weight learning exercise, learners review, study and discuss metric and customary units of mass. Students calculate the answers to forty two questions regarding different types of metric units of weight.

Several subjects are addressed within the context of a science instructional activity about the sun's ultraviolet rays. Elementary earth scientists consider protection of the skin with sunscreens (health), estimating and measuring...

An in-class and at-home assignment, young math stars find and list items from home and school that they think are one foot in length. Once the list is made, provide everyone with rulers to measure and find the actual lengths of their items.

Few topics engage young mathematicians as much as learning about money. Through a series of shared readings and hands-on activities, children explore the US currency system, learning how to count money and calculate change as they create...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Dare your class to drive dissolved carbon dioxide out of carbonated liquid at different temperatures to discover if there is a difference in rate. To make this experiment more sound, have explorers use equally measured amounts of soda...

Here is a very good estimating and measuring length with nonstandard units worksheet. Learners use paper clips and toothpicks to estimate and measure the real objects pictured in each problem, then write ten answers.

Try introducing this assigment on converting measurement by presenting a scenario: "Last night I found a recipe for cookies, and it called for a half pint of butter. All I had was measuring cups - what should I do?"...

Save those precious minutes and hours spent planning math lessons with this mini-unit on telling time. Offering a series of engaging hands-on and collaborative learning activities, these three lessons teach children how to read...

Scientists could measure the diameter of the sun before they knew its distance. Scholars construct a simple mirror box to measure the diameter for themselves. They compare this measurement with the official size, listed in a...

There's no need to think outside the box for this one! Scholars measure the length, width, and height of various boxes. Results help develop the formulas for the surface area and volume of rectangular prisms.

Determine the level of understanding within your classes using a summative assessment. As the final lesson in a 29-part module, the goal is to assess the topics addressed during the unit. Concepts range from linear angle relationships,...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Test young mathematicians' knowledge with an assessment aligned to California's fifth grade state standards. The exam covers a multitude of concepts including fractions and decimals, positive and negative numbers, measurement; and...
