Profit always seems to get everyone's attention. The same is true during a lesson on estimation. Learners use given information to estimate the cost of supplies for a painting job. They then develop a strategy for estimating the...

In this math worksheet, students learn to estimate sums and differences by completing step by step exercises. There is one word problem which is the example, and then students can choose from other estimation activities to do with a...

Sometimes dealing with decimals is so much easier than dealing with fractions. The ninth lesson in a 21-part module has the class consider situations when it might be easier to add or subtract fractions by first converting to...

Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves...

Learners use estimation to determine the answers to word problems by rounding whole numbers. In this estimation lesson plan, pupils compare and contrast solutions using the best answer.

Common Core is all about getting your learners to open their minds and think about the why and how. This problem has them thinking about unknown numbers and their relationship with one another when we round and...

Middle schoolers explore the concept of rounding. In this rounding lesson, students round fractions and mixed numbers. Middle schoolers estimate the sums, differences, products, and quotients of rounded fractions and mixed numbers.

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

Students explore the concepts of estimating and rounding. In this estimating and rounding lesson, students play a game of tic-tac-toe. Students pick items and must estimate their cost by rounding. Students estimate the costs of pretend...

In this estimating sums worksheet, students, working with a partner, practice problem solving five word problems involving estimation.

First graders practice rounding 4 digit numbers using place value concepts. In this estimating sums and differences lesson, 1st graders explore clustering, rounding, and front end estimation as methods for rounding decimals.

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...

Youngsters discover the difference between estimating and guessing. They estimate how many items are contained in a jar as they read a story. After the story, pupils discover the differences between estimating and guessing and create a...

First graders round to estimate greater sums. After a lecture/demo, 1st graders complete a web lesson on estimation. They practice rounding to the nearest hundred using a restaurant take-out menu.

For this estimation worksheet, students mentally solve eight multiple choice problems involving addition and subtraction. They arrive at their answers through the process of using compatible numbers or rounding. Students read story...

Second graders become familiar with need strategies for computation of money problems and estimating sums. In this computation lesson, 2nd graders solve real life problems to understand estimation and money problems.

For 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...

Fourth graders explore number sense by completing word problems in class. In this estimation lesson, 4th graders define terms such as sum, difference, estimate and best. Students complete estimating worksheets based on the concept of...

How tall is the Empire State Building? Lead your class through a collaborative estimation activity to determine the number of quarters it would take to reach the top and teach the following concepts: human capital, human resources,...

How do you balance a set of data? Using a ruler and some coins, learners determine whether the balance point is always in the middle. Through class and small group discussions, they find that the mean is the the best estimate of the...

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...

Help pupils explore estimation. They will make estimates and discuss when you might use an estimate. Then they discuss if their estimates are reasonable.

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...
