Go Ahead, Take a Guess! Estimating in the Real World
Learning how to use estimating to solve real life problems can be a great way for students to apply math skills.
Curated OER
Estimating Products
In this estimating products worksheet, students practice their large number multiplication skills as well as their rounding abilities. They are also challenged with word problems and a table.

Estimating Probabilities by Collecting Data
Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to...

Margin of Error When Estimating a Population Proportion (part 1)
Use the power of mathematics to find the number of red chips in a bag — it's a little like magic! The activity asks learners to collect data to determine the percentage of red chips in a bag. They calculate the margin of error and...

Estimating Probability Distributions Empirically 1
What if you don't have theoretical probabilities with which to create probability distributions? The 11th installment of a 21-part module has scholars collecting data through a survey. The results of the survey provide empirical data to...

Estimating Volume: The Money Munchers
Don't stuff money under your mattress. To find out why learners first complete a task determining how $24,000 in cash would affect the height of a mattress and whether this same amount would fit into a suitcase of given dimensions....

Estimating Length Using Scientific Notation
Would you rather have a million dollars or 1 x 10^6 dollars? To find the answer to this question, class members first complete an assessment task converting numbers between decimal notation and scientific notation. They then take...

Margin of Error When Estimating a Population Proportion (part 2)
Error does not mean something went wrong! Learners complete a problem from beginning to end using concepts developed throughout the last five lessons. They begin with a set of data, determine a population proportion, analyze their result...

The Difference Between Theoretical Probabilities and Estimated Probabilities
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...

Equal Estimates- Decimals
In this decimal estimation worksheet, students estimate a set of addition and subtraction problems, rounding to the nearest whole number, then place each problem in the box that contains its estimated sum or difference.
Curated OER
What Do You Think?
In this estimating sums and differences worksheet, students solve 6 problems in which the answer to a 3 digit addition or subtraction problem is estimated. Students then solve the problem for an exact answer. There will be carrying and...

All I Want For Christmas
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.
Curated OER
Estimate the Sum
In this rounding to find the sums worksheet, students round to the nearest thousandths and add. Students solve nine problems.
Curated OER
How Many Stars in the Milky Way?
Students perform an experiment in which they will use a statistical method called `sampling' to count to a billion (and beyond). Students practice sampling by estimating the number of characters on a page from the classified section of a...
Curated OER
Estimation 4: Sum and Difference
In this estimation worksheet, students read story problems, determine the correct operation, and mentally evaluate the problem by using compatible numbers or through the process of rounding. Students complete three multiple choice problems.
Curated OER
Estimating
In this estimating learning exercise, students solve 6 different problems that include some form of estimation in each. First, they define estimate as a way to round their answers sensible and carry out the calculation by hand. Then,...
Curated OER
Estimating With Decimals
For this math worksheet, students complete 14 problems where they estimate money amounts and multiplication products using numbers with decimals. Examples are provided in this well-designed worksheet.
Curated OER
Estimating The Number Of Civilizations In The Milky Way Galaxy
Students estimate the number of civilizations in the galaxy by first estimating the number of craters on the Moon and then by performing estimates of multiple-variable systems culminating in the use of the Drake Equation.
Curated OER
Estimating Expenses
For this estimation worksheet, students estimate expenses of different items by solving word problems. Students estimate expenses for 5 problems.
Curated OER
Estimating With Fractions
Seventh graders, exploring methods to estimate fractions, take notes on estimating fractions, 7th graders write letters to explain the process of estimating fractions and mixed numbers to someone who does not know the concept. Students...

A Relatively Far Out Idea: Estimating
Students investigate methods of estimating through cooperative group activities, hands-on activities, the use of tables and graphs and an interactive video.
Curated OER
Estimating With Fire
Learners solve problems with percents, decimals and fractions. In this algebra lesson, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.
