Students calculate the surface area of polygons. In this geometry lesson, students use spacial reasoning to find the answer to their problem. They analyze solids and create formulas to estimate the measurements of the area.

Young scholars estimate the amount of money they have in groups of pennies, nickels, and dimes. In this money lesson plan, students then count up the amounts they have and exchange money amounts.

In this addition worksheet, students round addends to the nearest 10 to estimate sums. A website reference for additional resources is given. One example is completed for students.

In this rounding to add worksheet, students round addends to the nearest ten and estimate sums for 14 problems. One example is completed; a website reference is given.

Seventh graders examine different transplant types and estimate the possible outcomes.  In this biology lesson students discuss donors and transplants then divide into groups and complete a worksheet.

Students calculate the volume of the Pantheon's columns and estimate changes in weight given different parameters.

Students measure and correlate their foot lengths and body heights, then use this data to estimate height of Laetoli hominids. They use metric measurement and graphing to determine these heights.

Eighth graders use goldfish crackers to simulate a capture-recapture method of data collection. They fill in a chart and determine the averages. They find the estimated population of fish and the actual population of fish based on the...

Fourth graders create wish lists from catalogues and sales ads based on a given budget. They add, subtract, estimate, and budget their given amount of money so they don't go over budget.

Sixth graders estimate, calculate and collaborate with students. They practice refusal skills.

Learners distinguish safe forms of radiation from those that are dangerous. Students watch a video about sources of radiation encountered every day. Learners estimate their own annual radiation exposure.

Students distinguish safe forms of radiation from those that are dangerous. Students watch a video about sources of radiation encountered every day. Students estimate their own annual radiation exposure.

Third graders select appropriate units for measuring and solving problems in customary systems, identify equivalent measures within measurement system, and estimate, determine, record, and discuss weight using appropriate customary...

Second graders define "pound," estimate and compare weights, and classify objects as weighing more or less than a pound.

Students estimate and compare temperature using degrees Celsius and Fahrenheit, and create mini temperature posters and answer questions about temperature.

Students begin with an analysis of loudness. They estimate the loudness of common environmental sounds, and then use their knowledge of hearing and loudness to evaluate the risk of noise-induced hearing loss for fictitious individuals....

Students view a Reading Rainbow video on germs and discuss microbial diseases. They grow cultures of Staphylococcus aureus and then estimate and graph the count for their own bodies and those of the class.

Learners estimate the population of a butterfly ecosystem and create a chart and graph based on information they find.

Young scholars explore the usefulness of algebraic skill development as they make decisions based on their ability to accurately estimate the speed of moving vehicles. The life and death possibilities place an interesting"spin" on this...

Pupils examine the phenomenon of sounds traveling slower than light. They discover why they see things before they hear them and how to estimate the speed of sound as homework.

Students define and compare health terms. They estimate a person's health status on each dimension of health. They describe the major determinants of health.

Students estimate the least squares fit line for a set of data. They understand error involved in least square fit lines. They solve application problems using least square fit lines.

Tenth graders estimate the size of an adult cheetah by research and measurement of a picture. They determine the approximate distance and speed of the cheetah from a filmed chase and compare that to their own running speed.
