Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...

Young mathematicians demonstrate what they know about measurement with a four-task assessment that focuses on estimation, length, and inches.

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,...

Curves ahead! Develop a numerical measurement of curvy-ness. The class is challenged to come up with a definition of curvy that can be applied to curves. The class members use their defined measurement to describe a curve.

A number doesn't have much meaning without a standard of reference. Learners read about the history of developing standards to measure chemical and physical properties and complete reading guides to process the information. They focus on...

Can your scholars crack the code of this metric worksheet? To start, mathematicians must convert different units of measurement to the standard metric system form. Then, pupils plug in the corresponding letter to the correct answer to...

How are your second graders progressing in their math skills? Find out with a series of math assessment activities. With baseline assessment score sheets for each skill, you can track how well your kids are adding, subtracting, telling...

Students convert among liquid measurement units. In this measurement lesson, students use Visual Thesaurus to gather information about customary units for liquid measure such as cup, pint, and quart, then students practice converting...

Students estimate measurements in real world problem situations. In this estimation lesson, students read the book Pancakes, Pancakes and estimate how many cups equal a pint, quart, and gallon. Students test their estimations by...

In this recognizing metric measurements worksheet, students read groups of three measurements and identify the one that is the smallest. Students solve 15 problems.

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

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...

It used watt amount of energy? This resource investigates the power usage of small household appliances. Using a watt meter, groups measure the actual wattage used by an appliance and then calculate the energy used daily. 

Explore the measures of central tendency through a challenging task. Given values for the mean, median, mode, and range, collaborative groups create a set of data that would produce those values. They then critique other answers and...

Teams learn about the size of a nanometer by measuring objects and converting those measurements. A worksheet then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small to...

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Pupils use the provided census data to guess the future height of a child. They organize and plot the data, solve for the line of best fit, and determine the likely height and range for a specific age. 

Would you rather have a million dollars or 1 x 10^6 dollars? To find the answer to this question, class members first complete an assessment task converting numbers between decimal notation and scientific notation. They then take...

Use a clock face to develop angles representing standard position angles. The interactive allows pupils to create angles using the hands of a clock. Scholars discover that there is a difference in the angle formed using a clock face and...

Customary units, also known as standard units of measurement, are the focus of a conversion brochure. Learners compare, identify, and convert customary units of length before folding the sheets into a brochure.

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Understanding arrays is very similar to understanding the relationship between multiplication and area. Give your third graders an opportunity to practice identifying area models that relate repeated addition and multiplication. They...

Investigate the meaning of a sample proportion using this hands-on activity. Scholars collect data and realize that the larger the sample size the more closely the data resembles a normal distribution. They compare the sample proportion...

Teach the basics of mass spectrometry with a hands-on activity. The fourth in a series of six lessons explores how mass spectrometry measures the ionic composition of an element. Learners then compare and contrast relative abundance and...
