What is a quick comparison, and how can it help you estimate sums and differences? For this estimation worksheet, learners estimate fractions in addition problems. They complete four problems where they estimate the sums after reviewing...

Work on rounding, estimating, adding, and subtracting with a helpful math worksheet! Fifth graders study different sets of addition and subtraction problems, and after rounding each number to the leading digit, they estimate what the sum...

By rounding, scholars find that adding money amounts becomes a breeze! They round two and three-digit numbers (with decimals) in these addition problems to get approximate sums. For each, mathematicians write the new addition equation...

In this estimation worksheet, students estimate the difference by rounding each two-digit number to the nearest ten. Students complete ten estimation problems.

In this rounding to find the sums worksheet, students round to the nearest thousandths and add. Students solve nine problems. 

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...

In this estimating worksheet, students round numbers to the nearest ten and estimate sums in a total of 9 problems. Answers are included on page 2.

In this estimating sums worksheet, students round each number in addition problems to the nearest hundred and solve. Answers are included on page 2.

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.

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...

In this Drake Equation worksheet, learners 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...

In this estimating sums activity, students review two steps to help them estimate to find sums. Students then round each addend to the nearest ten and use the number line for help. Students estimate the sums and write the numbers on the...

In this estimating sums worksheet, students round each addend to the nearest ten and then estimate the sums. Students finish with one test prep question by estimating for the sum.

For this estimating sums worksheet, students round each addend to the nearest ten using the number lines. Students then estimate the sum for each addition problem.

In this estimating sums worksheet, students use the table with point totals from a ring toss game. Students use the total points to estimate the sums for each word problem.

In this estimating sums worksheet, students solve the six word problems using the information within the problem to estimate the sums.

In this sums and differences learning exercise, 6th graders solve 20 different problems that including the estimation of numbers in each one. They estimate the sum or difference found in each problem and write it in the space provided....

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...

In this estimating sums worksheet, students solve 6 word problems where they estimate the sum of 3 digit numbers by rounding to the nearest 10, 100 or 1000.

In this rounding whole numbers and estimating sums and differences worksheet, students problem solve and calculate the answers to forty two mathematical equations.

In this estimation of sums and differences learning exercise, 7th graders solve 20 different problems that are related to estimation of numbers. They add or subtract each problem as shown. Then, students estimate the sums and differences...

In this estimation activity, students complete ten estimation problems by rounding each number to the nearest ten. These are all two-digit subtraction problems.

Pupils learn the steps for basic constructions using a straightedge, a compass, and a pencil. Pairs develop the skills to copy a segment and an angle, bisect a segment and an angle, and construct parallel and perpendicular lines.
