In this metric measurement learning exercise, students estimate lengths of items in centimeters, then use rulers to check estimates.

Students explore fractions. For this fraction lesson, students estimate fractions and estimate sums of fractions. Students work with technology to develop math fluency.

This is great go-to activity for those spring or fall days when the weather beckons your geometry class outside. Learners start with a small tree, devising strategies to accurately estimate the leaf count. They must then tackle the...

Just when a young mathematician starts to feel comfortable turning word problems into linear equations, shake things up and throw inequalities in the mix. This excellent, instructive presentation takes the steps for solving an...

Don't be irrational! Use this pre-test to assess your classes' ability to work with all types of real numbers. The lesson asks learners to estimate value, evaluate roots, and order numbers. This begins a series of lessons on the real...

Given populations of the five Northwestern states, learners create a circle graph. Using the data and the pie chart, they make comparisons between the populations of the states. Finally, the pupils determine how the chart will change...

How do the area and perimeters of circles and squares compare? A clever video illustrates the change in the area of a circle and square while their total perimeter stays the same. The task is for learners to predict the point where the...

Make sure there is enough ice cream on hand. Learners try to find out how much ice cream to buy for a sports event. Scholars use a pie chart showing the percent of a sample of people who like different flavors of ice cream. Using the...

Do some interpretive modeling. Class members watch three examples of interpreting key features of a graph of a quadratic to find solutions to a real-world problem. Learners review how to find the key features on a graph using technology...

The shape of the histogram is also relative. Learners calculate relative frequencies from frequency tables and create relative frequency histograms. The scholars compare the histograms made from frequencies to those made from relative...

Second graders, in groups, estimate amounts in various jars. They sort each jar from least to greatest amount.

Fourth graders estimate the surface area of a pond using the chance method and the estimation method. They complete a graph and a short report comparing the results of the two methods.

In this math learning exercise, students are assessed on their basic math skills. Included are questions on multiplying and dividing by 10 and 100, place value, basic word problems, rounding, estimating and comparing numbers.

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.

Second graders estimate how much volume a container can hold. In this math lesson, 2nd graders compare their estimates with actual measurements. They share and discuss their results in class.

Students use the Runaway Journeys site maps and image resources in rounding out their study of the slave migration. They access an excellent multi-media narrative imbedded in this plan.

Students explore estimating and measurement with the story of Jack and the Beanstalk. They read and discuss the story, estimate and measure their own height, circumference, and length of their foot, and draw and paint a giant using...

Learners multiply decimals and/or mixed numbers. They explore the effects of multiplying decimals and mixed numbers. They practice estimating answers when a number is multiplied by a decimal or mixed number.

Students explore estimation. They estimate distance, weight, temperature and elapsed time. Students record their estimates and justify their estimations wtih a written response. After estimating, students take the actual measurements of...

Students explore how jelly beans are produced. They discuss the origins of the jelly bean and view a video about how jelly beans are prepared, tested, shaped, finished, and shipped and estimate the amount of jelly beans in a jar and sort...

For this multiplication of decimals worksheet, students problem solve twenty five equations that deal with multiplication of decimals and rounding answers to the nearest whole number.

In this math worksheet, students find the best estimate by using the skill of rounding. The answers are written in the spaces at the bottom of the page.

In this mathematics worksheet, students identify that the spiders each used a different angle to create their webs. Then they find out each spider's angle by estimating and measuring.

In this math activity, students answer 303 problems including addition of numbers with decimal points, multiplication word problems, and rounding numbers to the nearest one thousand.
