How many hot dogs does Fenway Park go through in a year? Learners estimate answers to this question and more as they work through the task. Problems require participants to make assumptions and use those assumptions to make estimations.

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

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...

Roses are red, but did you know that some are lighter while others are darker? Scholars read an infographic to decipher the fraction and percent of rose color and their country of origin. They go on to make comparisons and estimate while...

Take the resource out of the file cabinet. Young mathematicians estimate the number of sticky notes it would take to cover the surface area of a file cabinet. They answer a set of questions on how the number of sticky notes would change...

A brilliant resource is at your disposal. Future consumers investigate and discuss an electric bill. Given only partial information, they estimate the monthly bill. They then consider how tiered pricing will affect the bill.

Block play can teach children about gravity, physics, and spatial relationships. A hands-on lesson incorporates these concepts with an activity in which learners examine the relationship between levels in a pile. Scholars begin to...

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.

Keep playing with those old toy cars! Pupils estimate the number of toy cars in an art installation. The only information they receive is a picture showing the toy cars arranged in concentric rings and the diameter of the overall...

It'll take as long as it'll take. After watching a short video clip of someone moving a lawn as well as a running stopwatch, pupils estimate how long it would take to mow the entire lawn. Provided diagrams show the dimensions of the lawn...

What? The calculation of area is a linear distance? A short video shows how to use the areas of simple polygons to estimate the area under a graph. Pupils divide the area under a curve into figures to easier calculate the area. Given...

Find an easier way to double it. Using the price of an item and the Consumer Price Index, learners determine how long it will be for the price to double. Scholars calculate the length of time it would take for the price to double using a...

How can you place a rectangular tile around a pipe? Scholars first use a model of a kitchen sink cabinet to take measurements. Using a compass and their knowledge of circles, they then cut out a circle from a piece of poster board (which...

High schoolers begin a discussion on diversity and determine the percent of the population that speak another language at home in the US. Classmates make a prediction of the percentage of people that speak another language at home in...

Students explore a variety of math concepts. In this integrating technology lesson, students visit online webtools such as Max's Math Adventure, I Know That Math, Hands on Banking, and more.  A description of each website is provided.

Third graders use estimation, fractions and decimals to determine the perimeter of objects in the classroom. They are given a worksheet with a list of the items on it. The worksheet has columns beside each of the items for estimation and...

Students practice making reasonable estimates. In this consumer math, students round purchase prices of items to estimate the total cost. Students practice using metal computations to arrive at estimates.

Students work collaboratively to determine how many crackers are in a large container. They then view a video to see how often people use estimation in their jobs, and another video to watch students work on figuring out appropriate...

Students explore the concept of estimation. In this estimation lesson, students create their own estimation jars and fill them with objects of their choice. Students then count the exact number of objects and trade jars to...

Second graders measure surface area and perimeter using estimation. They complete a variety of measurement activities using Cheerios breakfast cereal.

Students gain the powerful tools of estimation, prediction, and averaging and discover the importance these tools have in daily living.

Students participate in an estimation activity to determine the length of a hallway or to estimate how many people can fit in the school stadium or gym.

Students discover the advantage of estimation over simple guessing using number relationships. They also discover how useful a mathematical tool estimation is in everyday life.
