Students work with patterns. For this pattern lesson, students find AB patterns in nature and the manmade world. They create their own AB pattern using math manipulatives and visual arts. 

In this counting method, students solve simple and compound probability problems.  They determine the number of permutations and combinations that can be made under given circumstances.  This two-page worksheet contains 23...

Build on probability and incorporate a random number generator to select outcomes for a school election. Your learners will record their results on a dot plot and answer questions regarding whether their candidate has a chance at the...

Third graders model the tag and recapture of bears and use proportions to estimate the population of the bears in their forest. This is a statistical sampling method used by scientists and naturalists to determine population numbers.

When astronauts get hungry in outer space, they can't just call and have a pizza delivered. In order to gain an appreciation for the challenges associated with space travel, young learners are given the task of selecting,...

The class gets their mean and median all in a row with an assessment task that uses a population of ducklings to work with data displays and measures of central tendency. Pupils create a frequency chart and calculate the mean and median....

For this student opinions survey worksheet, students solve and complete 3 different problems related to conducting a students survey of opinions. First, they describe in detail a practical method for selecting a sample that uses...

How can you compare linear functions? The seventh installment of a 12-part module teaches learners how to compare linear functions whose representations are given in different ways. They use real-world functions and interpret features in...

First graders explore the existence of patterns in everyday items. In this science and math integrated lesson, 1st graders match leaves with a name word card and organize them into four patterns. This lesson includes a reading of And the...

In this division riddle activity, 4th graders solve twelve division with remainder problems, write the code letters, then rearrange the code letters to solve the riddle and write which method they used.

Students solve math word problems. In this cool tools lesson, students are introduced to the K-N-W-S method.  Students work in groups and complete a worksheet using this method of learning. 

In this explaining answers worksheet, students read the word problem about a passenger helicopter and its speed abilities. Students use the understand, plan, solve, and look back method to solve the problem and then explain how they...

Six pages prepare you to introduce your math stars to the addition and subtraction of positive and negative numbers. They drive a robot back and forth on an actual number line to represent the operations. If you don't have access to a...

Seventh graders investigate the data related to finding the favorite type of pizza that 7th graders eat. The data is analyzed taken from a survey that focuses on the toppings of the pizza and not the brand. Students practice the sampling...

Learners design questions that can be answered by collecting data. In this line-plot lesson, pupils collect data and graph on a line plot on world records. An abundant supply of teacher support is provided in this resource.

Students explore and experiment with the concept do new kinds of insects appear after soil modification. They assess and review scientific methods of observation, predicting, variables, math skills, ratio, proportions, graphs and the art...

Looking for an estimation activity a bit more involved than the typical "guess the number of jellybeans in the jar" game? Here, learners use a picture to estimate the number of people at a large event, look for potential problems with...

Working individually and collaboratively, geometers gain a clear understanding of the Pythagorean theorem. They create, explain, and compare proofs of the theorem. Proofs involve areas of trapezoids, squares, and triangles, congruent...

Do you separate your trail mix before eating it? Then you've been separating mixtures your whole life! Scholars model a contaminated soil sample using trail mix and estimate the percentage of each component. They consider how to clean up...

In this interactive Internet  assignment, physical science investigators answer 11 questions about the atom, the subatomic particles, and atomic structure. They can click on "Reveal Answer" to discover if they are correct. They also...

Students explore the use of variables in the scientific method. They identify the dependent and independent variables through pH testing. Students construct graphs of their data and analyze their findings.

Students identify a question to generate appropriate data and predict results. They distinguish between a total population and a sample and use a variety of methods to collect and record data. Students create classifications and ranges...

Students use several examples to create a method for adding and subtracting fractions with unlike denominators. They present these methods to the class and then practice applying methods to sample problems.

Students use a similar method to the Lincoln Index to estimate a population size.
