Fourth graders practice measuring different objects in inches. Individually, they estimate the length of the same object in centimeters and then calculate the actual length. They compare and contrast their estimate to the actual length...

Students collect sunflower heads from their community garden. They estimate its seed count using different strategies. They graph their estimations on a graph and use calculators to find the actual total.

Students estimate and record the number of raisins in a snack-size box. They also graph their results and note the differences (+ or -) from their estimate and actual number.

Fifth graders use estimation to solve problems and assess the reasonableness of their answers. They may use an odometer, a map with a legend, MapQuest, or a map without a legen. They estimate 4 to 5 different scenarios.

Students investigate how to estimate the age and size of turtles, and examine variability in scientific data. They read an informational handout, identify the parts of the shell, measure the shell and estimate the age, and record the...

Fifth graders study latitude and longitude. They estimate the latitude and longitude of their hometown and find the latitude and longitude of other cities using a map. They use a website to find out the cities' actual latitude and...

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Students use the language associated with probability to discuss events including those with equally likely outcome. They collect data from a simple experiment and record in a frequency table: estimate probabilities based on this data

Students use estimation as a math strategy. Students estimate the number of small snacks that are presented to them. Students count the snack items after they have estimated how many there are, before the class snack on a daily basis.

First graders are introduced to how to use a ruler and its purpose. Using a boomerang, they estimate its length and then measure it using a string and ruler. In groups, they practice the same exercise with various objects while...

Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Sixth graders discuss the characteristics of specific angles and then use the information to to identify and estimate given angles. The class goes outside, identifies north, and turns a specified amount of degrees. Using a given compass,...

Pupils study the use of X-ray data to make size and energy estimates of the source and the processes occurring there. They use XTE observations of the object GRO 1744-28 to determine whether bursts occur periodically and the duration of...

In this estimating percentages worksheet, students read a problem that gives the percentage of a dollar amount, for example; 8.6% of $75.09 = $5.46. They estimate to determine if they believe the problem is "definitely wrong" or...

Students discuss and explore different methods that can be used to estimate from the video. They practice estimation skills by recreating a sample problem from the video. Web sites containing other estimation activities are included

Students perform a classroom activity of measuring the angular size of something from several distances. On the Internet, they obtain and examine images with various magnification factors and estimate the angular size of Andromeda.

Twelfth graders utilize the computer and various software programs in order to design a 3 dimensional package which they submit a cost estimate sheet of production in their oral presentation.

Students estimate the material needs for a concrete block foundation of a given size, with a given number of openings.

Students demonstrate how much paper is thrown away in their classroom in one week. They estimate the weight of paper used, weigh the paper at the end of five days, and discuss how students can use less paper.

Students are read a book about ladybugs. Using the test, they estimate which page shows the longest trip the ladybug made. They assemble their own ladybug book by following directions on a worksheet. They take measurements on each...

Pupils discover how to estimate the age of redwood trees. They measure the trees' diameters by using string to calculate the circumferences. Students conclude by discussing the science of dendrochronolgy.

Students use Hudson River salinity data to create a line graph that shows the location of the salt front, and use math skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...

Students develop useful strategies for mental calculation when estimating possible addition solutions. They mentally perform calculations involving addition and subtraction. Students state the estimated sum or difference between numbers.

In this math worksheet, students use a variety of non-standard measurements units to find the lengths of objects on paper and around the room. Students first make an estimate, then measure with different units.
