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.

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...

Use pumpkins of various sizes to experiment with weight and perimeter. First the class lifts the pumpkins one by one, estimating each pumpkin's weight. They arrange the pumpkins from lightest to heaviest, and then string weigh each one...

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...

Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

In this math worksheet, students round numbers to their leading digit. They multiply the results to find the estimation of the exact answer. Students estimate and then find the exact answer on six problems.

Students examine how archaeologists preserve context of sites through use of rectangular grid or Cartesian coordinate system, and develop sense of distance by pacing off and estimating distances.

In this math worksheet, students will work with a coach to add numbers with decimals to the hundredths place. Students will follow a step-by-step process and notes are provided for the coach.

Teach your class a thing or two about making educated mathematical guesses. Learners read a passage that explains estimation and approximate and exact answers. They then respond to five questions about and related to the text.

Learners explore linear measurement. They choose appropriate measuring tools, measure three classroom items, and record their results.  A class discussion ensues in which everyone decides the best way to present their data.

Young scholars construct simple altitude tracking devices for determining the altitude a rocket reaches in its flight. They estimate the altitude a rocket achieves during flight.

Assess scholars' knowledge with a 22-page assessment that covers place value, patterns, probability, estimation, measurement, geometric figures; and their ability to add, subtract, multiply and divide proficiently. 

Students listen to the reading of "The Button Box" and use buttons provided to tell a story about a chosen button, compare their own buttons to those in the reading. They estimate how many buttons are in a bag and sort buttons based on...
