How can you complete a simulation when it is not practical to determine the probability of an event? Class members learn that in some situations, it is not feasible to find the probability of an event, but they can estimate it by running...

Watch animated slides as RJ explains how to round numbers to the nearest ten and thousand. Viewers then get a chance to try it themselves.

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.

It is about this big. An assessment provides three questions on the estimations of volume. Pupils determine the quantities needed and use dimensional analysis to arrive at estimations involving dollar bills, paint, and gasoline.

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...

Estimating is an essential skill used in everyday life. This presentation explains how to apply prior knowledge about rounding numbers to estimating sums and differences. Example problems and assessment include large numbers, making this...

It seems like it should be about three. Pupils learn to get an estimate of the derivative of a function at a point by using the derivative functionality of their graphing calculators. They take that information to determine the equation...

Find the percent of middle schoolers who want the ability to freeze time. The 21st installment in a series of 25 has groups collect a random sample of respondents who answer a question about superpowers. Using sample statistics,...

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

How many of the pupils at your school think selling soda would be a good idea? Show learners how to develop a study to answer questions like these! The lesson explores the meaning of a population versus a sample and how to interpret the...

Add some randomization into simulations. The 11th installment in a series of 25 presents two new methods to use in simulations--colored disks, and random numbers. Pupils use random numbers to run simulations where the probabilities make...

Expand on prior knowledge of place value to teach your class how to round whole numbers. This essential skill is explained with the help of a number line before introducing the explicit rules for rounding numbers up and down. Work...

How many hours should learners devote to studying outside of class? Learners use this worksheet to not only practice estimation, but also develop a valuable study skill for their future academic careers.

Determine medians within a group. Given data represented as a frequency table of grouped data, the video demonstrates finding an estimation for the median. After finding the group where the median resides, the presenter uses a formula to...

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...

Finding out how to calculate tax and tip is a valuable skill that all young adults should be able to do without a calculator. Learners are given a bill and asked to calculate the tax, tip, and total amount. Calculations can be exact or...

Reinforce measurement skills with a holiday-themed worksheet that challenges mathematicians to estimate and measure the length, width, and height of classroom objects using a gingerbread man. 

How much does a seagull weigh? Kids estimate weight by choosing the closest option out of three, using ounces, pounds, and tons. 

In this mathematics activity, 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.

Read carefully, look for key words, eliminate, estimate, check your answers. Give your youngsters the strategies for approaching multiple-choice problem solving, focusing on multiplication and division of whole numbers, with this...

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math instructional activity. Using the coding formula listed, children learn to fluently estimate...

Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th instructional activity in a series of 21 has scholars use the ICESat data to understand...

You can't evaluate an irrational root expression without a calculator—or can you? Scholars estimate the value of roots within an expression to approximate the value of the expression. Expressions include a mix of square roots and whole...

Using clocks as dining tables? Scholars estimate the number of people that can sit around the face of the clock on the Royal Liver Building in Liverpool. They use estimation to justify their responses.
