Grasshopper Mark and Recapture (GMR)
Learners estimate the density of a population of insects (grasshoppers) at a given life cycle stage in a given type of habitat.
Curated OER
Smoke Signals
Students estimate the amount of money a non-smoking teen spends in a week, a month, and a year, and compare it with the expenses of a teen who smokes one, two, and three packs a day. They research other reasons that teens should not smoke.
Curated OER
Hi, Deer!
Students collect, organize by table, and examine census data in a simulation, estimate the size of the population in the simulation and make predictions based on the collection of census simulation data.
Curated OER
Extraordinary Extrapolation
Students study how scientists have estimated the maximum height to which trees can grow, and assess the reliability of interpolation and extrapolation techniques by making predictions with particular data sets and analyzing accuracy of...
Curated OER
The Discount Is Right
Students estimate and calculate the sale price of five items using the original price and a designated rate of discount. They use percent to calculate the rate of discount and the original.

ExplorA-Pond:2nd Grade Perimeter
Second graders visit a real pond. They estimate the pond's perimeter using "student feet." In groups, they measure the pond's perimeter-each group measuring a section of the shoreline. They convert student feet into actual feet and find...
Curated OER
Capacity
Eighth graders explore the term capacity and understand the word's meaning. They participate in several lab stations set up around the room in which they will estimate how many scoops it will take to fill the container. They then will...
Curated OER
Lesson One: Perimeter, Area, Volume
Students explore perimeter, area and volume. Using geoboards, toothpicks, and marshmallows, students create specific shapes. They are directed to use formulas to find the volume, area, and perimeter of the created shapes. In groups,...
Curated OER
Making Benchmards--Length
Students explore the idea of having Benchmarks to estimate the length of given objects. Students demonstrate acquired knowledge of the basic units of length by making reasonable estimates. Students create a personal benchmark.
Curated OER
Telling Time
Students estimate, measure, and compare the passage of time using minutes, half hours, and hours. They read the book 'It's About Time, Max!' with the teacher and draw an analog clock face. They show the time and 30 minutes later, 15...
Curated OER
Natural Selection
Students estimate how many different species of organisms inhabit the Earth. In groups, they match the pictures of embryos at the different stages of development. They compare and contrast animals from the sky, land, and water and...
Curated OER
Data Analysis and Probability
Students design models to simulate actual events using various random devices. They estimate the likelihood of a particular outcome using results of simulation. In addition, they simulate the births of three children to a using a coin.
Curated OER
Designing Models to Simulate Actual Events Using a Random Number Generator
Students design models to simulate actual events using a random number generator on a calculator. They estimate the likelihood of a particular outcome using results of simulations. Answer Key included.
Curated OER
Differentiation
Learners explore estimated and exact results for derivatives, tangent lines, implicit differentiation, and symbolic differentiation. The lesson provides examples with solutions and practice problems.
Curated OER
Catch, Tag, and Release
Learners discover how fish tagging is used by marine biologists and fisheries to estimate fish populations. Participating in a simulation, learners use estimation to determine the whole population from a small number of items.
Curated OER
Estimating and Measuring
In this math learning exercise, student estimate the lengths of a variety of objects. Then, students measure the actual length of each object.
Curated OER
Measure Mania
In this measurement instructional activity, 3rd graders, working with a partner, choose two different units out of five to measure the length of their classroom. Students estimate first and then measure.
Curated OER
Estimating Sums and Differences
In this estimation worksheet, 4th graders estimate the sum or difference of 15 math problems. Students write their answers underneath each math problem on the worksheet.
Curated OER
Explore Volume
In this finding volume practice worksheet, students sharpen their problem solving skills as they solve 6 problems that require them to estimate and to find volume.
Curated OER
Metric System Notes
In this metric system worksheet, students complete notes on measurements used in the metric system, the metric system prefixes and estimates of measurements of length in centimeters.
NASA
The Drake Equation
In this Drake Equation activity, students read about how scientists can estimate the number of intelligent civilizations that may exist in our galaxy. Students answer 7 questions about the Drake Equation and they use the internet to find...
Curated OER
A Close Encounter of the Tree Kind
Students study trees in their natural habitat. In this tree lesson plan, students complete a number of outdoor activities to estimate the height of a tree, examine how bark can be a distinguishing tree characteristic, and how to make a...
Curated OER
How do You Stack Up? Revisited
Students estimate the thickness of coins. In this stack up instructional activity, students stack pennies, nickels, dimes and quarters. They calculate and record the thickness of each coin. Students stack coins and estimate the height...
