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 a six-problem learning activity, children are guided to solve word problems that involve rounding to the nearest ten and nearest hundred. A commentary and answer key provide different approaches that learners may take in solving the...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Fourth graders explore rounding a price given in dollar and cents to the nearest dollar. In this math instructional activity, 4th graders discover how to round to the nearest dollar. Additionally, students practice rounding money for...

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...

Students explore the concept of rounding.  For this rounding lesson, students use their calculator to round three digit numbers to the nearest 10 or nearest 100.  Students round fractional numbers to the nearest tenth,...

Youngsters discover ways to estimate. They will use two jars with large and small items and estimate the number of items. Then record their estimate and explain why they answered the way they did. They try this experiment with different...

Students predict how many steps they think it will take them to get from the front of the room to the back. They record predictions on paper and then into database and then actually test by walking foot to foot to their destination...

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...

They apply various strategies in their estimations. They analyze the differences between guessing and estimating. They estimate the number of beans and jellybeans in egg cartons and jars respectively.

Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

Via the concrete setting of estimating the population of the US, your algebra learners are introduced to a logistic growth model. Comparing and contrasting logistic, exponential, linear and quadratic models, to see which fits the data...

Statistics can be manipulated to say what you want them to say. Teach your classes to be wise consumers and sort through the bias in those reports. Young statisticians study different statistical reports and analyze them for...

Seventh graders explore random sampling by estimating the number of e's on the newspaper. They explain the possible error sources for this type of sampling, and compare the accuracy of sampling a small and large population. This is a...

How many cars would be involved in a traffic jam 12 miles long? A slightly ambiguous writing prompt gives learners the opportunity to practice making reasonable assumptions to tackle a real-life problem. Few details are given, so they...

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.

Learners practice estimating by handling items in groups of ten. They visualize how much space 100 items, such as pennies, peas, or beans, will take up after holding 10 of them. Students measure the difference in volume between 10...

Hooray for chocolate chip cookies! Ask your mathematicians to triple a chocolate chip cookie recipe and then reduce the recipe by one-fourth. Your class may need two days to complete, tripling the recipe the first day and reducing the...

Your statisticians draw several samplings from the same data set, some randomized and some not, and consider the distribution of the sample means of the two different types of samplings. The exercise demonstrates that non-random samples...

Students identify six different simple machines. They investigate the difference between the ideal and actual mechanical advantage. Students calculate the actual mechanical advantage for several simple machines.

It's just a sign of the times. Given a billboard with distances and travel times to two different interstate highway junctions, learners determine the speed limit. They must incorporate the concepts of distance, rate, and time with that...

Students solve problems with percents, decimals and fractions. In this algebra lesson plan, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.

Students use the Live Access Server (LAS) to form maps and a numerical text file of snow cover for each continent on a particular date. They analyze the data for each map and corresponding text file to determine an estimate of snow cover...

Simulate a random sampling of data by tearing 20 sheets of paper into slips and place a number on 10 and a letter on 10. They place the slips in two separate containers and randomly draw a number and a letter. They record their...
