Students explore the global grid system. In this globe instructional activity, students identify latitude and longitude lines and how these can tell the coordinates of any place. They use the Internet to find the exact coordinates for...

Students participate in a measuring scavenger hunt. Students choose items around the room to estimate and measure. Students try measuring with their hands and compare with other students who did the same. Students discuss why their...

In this angles worksheet, students estimate angles to within 15 degrees, then measure and name each. A reference web site is given for additional activities.

Young scholars explore the concept of equivalence as it relates to comparing concrete objects to determine greater or lesser attributes such as length and weight. In this pan balance-shapes lesson, students make estimations while...

Pupils use the problem solving strategy of guess and check to investigate math word problems. They determine which problem solving strategy or strategies would work best in problem situations.

Challenge your class to use straight lines when estimating the length of a curve. An engaging interactive allows individuals to place line segments one after another along the arc. Learners determine that the more lines used, the better...

Approximate the volume of a solid of revolution. Using a method similar to approximating the area under a curve, pupils investigate the volume of a solid of revolution. The learners use a given definite integral to find the volume of...

Go big or go home! Learners watch a video rendition of the creation of a penny pyramid. Their task is to determine the number of pennies in the pyramid. The lesson encourages multiple methods, including function building or volume formulas.

Continuing from the previous instructional activity, scholars work on mastering the skill of multiplying decimal fractions by a whole number. The method employed in the instructional activity is to convert the decimal fraction to its...

In this fraction estimation worksheet, students complete eight problems where they estimate the fractions to the nearest whole number. The fractions on the worksheet are mixed and improper.

Sixth graders calculate the amount of rice there will be if the amount is doubled everyday. In this multiplying lesson, 6th graders are given an amount of rice that is grown each day. Students then calculate how much rice there will be...

In this mathematical calculations instructional activity, 4th graders complete 12 multiplication problems by using a calculator. Students also develop an estimate for these problems.

In this mathematics worksheet, 3rd graders write the numbers for each problem. Then they write each in expanded form and the numbers from least to greatest. Students also estimate first by rounding the numbers to the nearest hundred.

In this customary length worksheet, students solve 4 problems where they must choose the better estimate of length. Students solve 12 problems where they must compare, convert and order customary lengths.

In this mathematics learning exercise, 3rd graders draw lines for each measurement. Then they measure the lines to the nearest centimeter. Students also use a ruler, a measuring tape, and measure small items and longer items.

Students estimate the altitude of a rocket during several flights. They create their own altitude tracking devise. They examine and discuss their results at the end of the activity.

Students complete experiments to determine how rocket fuel is affected by surface area and temperature. They compare the reaction rates of antacid tablets. They discuss their results to complete the lesson.

Which unit of measurement would you use? As your scholars begin to understand measuring, it's important they become familiar with the various units. They examine five object images and match them to one of five units: meters,...

Students practice estimating and counting and using a ruler to measure distance.

In this estimation with weight and volume activity, 5th graders solve and complete 6 problems that include estimating objects. First, they determine which item illustrated weighs more. Then, students determine which figure illustrated...

Students calculate the reproductive rate of a plant that creates multi seed fruits. They graph exponential growth and the complete a series of questions that help them infer that natural selection processes are at work in this population.

In this estimating quotients worksheet, students solve 20 different problems that include estimating a variety of quotients in each. They divide each whole number and then estimate the answer in each problem to the nearest whole number.
