In this math instructional activity, students learn the divisibility rule for 9s-- if the sum of the digits in the dividend is a multiple of 9, there will be no remainder in the quotient. Students complete 27 division problems with a 4...

Your class will learn what it means to take a random sample of a population and to draw inferences from the information gained. In part a, of the exercise, you discuss with your class how young scholars during a class election can be...

For this Pythagorean theorem for algebra I worksheet, students answer 10 problems finding the missing side of a right triangle using the Pythagorean theorem.

Eighth graders use a meter stick that is placed on a horizontal surface and an object is moved along it so that the shadow length can be measured at different distances from the light source. They solve real-world problems involving...

The class gets to practice being a mathematician in ancient Greece, performing geometric application problems in the way of Eratosthenes. After following the steps of the great mathematicians, they then compare the (surprisingly...

Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

Track down the Cyberchase episode that this lesson is associated with. Using a worksheet that is embedded in the plan, learners must find the next two numbers and shapes (a double pattern). Once these have been discovered, pupils try...

Elementary schoolers use their understanding of place value to develop a strategy for a number game. In this lesson, pupils use place value to play "100 or Bust" and figure out a good winning strategy. These kinds of math games are...

Explore politics by analyzing the voting process. Pupils discuss the purpose of casting votes in an election, then examine graphs based on the data from a previously held election's turnout. The instructional activity concludes as they...

Looking for a different way to introduce long division? Need a shortcut for checking multiplication answers? Then this is for you! The multiplication method uses a quick trick to check for accuracy. The division method allows learners to...

Here are a some pre-made sets of data that kids can use to practice data analysis. There are 10 survey scenarios written out, and scholars synthesize the results of each into a bar graph. In addition to the graphing, they answer two...

Use these pre-made data sets to introduce kids to bar graphs and data analysis, and then have them take surveys on their own. There are 10 survey scenarios written out here, and scholars synthesize the results of each into a bar graph....

When a random sample isn't enough, your math class can compare the data from a physical simulation to decide if the probability is still likely. The instructional activity is part of a probability series that focuses on one question and...

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...

You know you have stumbled on something interesting when you launch this app. You are suddenly taken into a world of mystery and intrigue, and of course, math-skills practice.

Students explore the process of decomposition. For this ecology and measurement lesson, students prepare a worm home to be used for vermicomposting. Students weigh a group of worms and the added food, recording this information on a data...

Young scholars create and conduct a survey. In this broken bones activity, students discuss if they've ever broken a bone and how a broken bone heals. Young scholars generate questions for a survey on broken bones and healing time,...

Eighth graders find the range, median, mean, and mode of a data set.  For this finding the range, median, mean, and mode of a data set lesson, 8th graders collect data about the high and low temperature for 10 different...

Fourth graders generate an oral presentation on the weather. In this weather lesson, 4th graders watch the weather for a week and record the data on a chart. Students give a weather report at the end of the week.

Students make a sundial. In this time lesson, students determine the time of the day by creating a sundial. They check the time on the sundial, hourly, for one week. Afterward, they explore what happened to the shadows in reference to...

How did ancient peoples determine the height of really tall objects? Young scientists and mathematicians explore the concept of using shadows to measure height in a hands-on experiment. Paired pupils measure shadows, then calculate the...

Time to learn about sundials. Scholars see how to build sundials after learning about Earth's rotation and its relation to time. The unit describes several different types of possible sundials, so choose the one that fits your needs — or...
