In this rounding and estimating worksheet, students solve 18 rounding and estimating problems. Students solve problems without a calculator.

In this averages and percents activity, students identify and define average as all numbers together divided by the total number of items added. Then they identify and define percent as the given number out of a total possible. Students...

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

Pupils try to get a collar on temperature with a short assessment item that asks them to compare two different methods in converting Celsius to Fahrenheit. Individuals try to find out when an estimation provides conversions that are...

What is your favorite animal at the zoo? Young mathematicians answer eight multiple choice questions, based on a survey of 50 people presented in a pie graph. Additionally, the graph does not display any numbers, but rather...

When it comes to money math, show scholars that estimation is their best friend. They round money values to the closest dollar, 10 dollar, and 100 dollar increments, solving 19 addition and subtraction problems with approximate answers....

Develop a model for a hanging chain. Pupils find a mathematical model for a hanging chain and then they compare their models to the precise function that models the curve. Scholars come up with a strategy to determine how close...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Upper graders experiment with measurement. They estimate the length, volume, and weight of various objects, then rotate through stations making predictions concerning measurements and then testing their predictions.

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...

Without using a ruler, learners estimate the relative length of various lines in these three scenarios. The first two are set up as maps, with learners determining the shortest and longest distances from one position to another. The last...

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...

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...

Investigate the length of various objects in metrics! In this measurement lesson, 2nd graders estimate and find the length of objects in the classroom using centimeters.

What a creative way to delve into adding large numbers! After listening to a story called The King's Chessboard, learners estimate how much money they would have each day following instructions based on doubling and exponentially...

Trying to get your class to think of decimals as fractions and vice versa can lead to interesting discussions. After all, we can usually understand quickly that 1/4 is .25 but why is 1/7 not so easy to convert? This activity looks...

Enrich your study of food science with with these math worksheets. They offer a variety of food-related word problems that are great practice for multiplying, identifying fractions, estimating length, and performing calculations...

The square root of five and five do not have the same value! How many times have you addressed this with math classes? A lesson gives an explanation of a square root and gives examples for simplifying square root...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Young mathematicians determine the number of hours it would take judges of the "Z Factor" television talent show to watch every act. Participants make estimates and assumptions to solve the problem.
