A rich and well-designed lesson on estimation is here for you. The lesson utilizes a video; ITV Series: The Eddie Files 'Estimation: Going to the Dogs,' along with many websites. Several fantastic learning activities are...

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.

Sometimes simple is just better. A set of activities teaches young mathematicians about using plausible estimation to solve problems. They break problems down to simpler problems, use rounding and estimation strategies, and consider...

This is a twist on the old "guess how many jellybeans" game. Using estimation and math skills, learners participate in a fun "mystery jars" activity, trying to make educated guesses at how many objects are in two jars. The basic activity...

Discover creative ways to use surface area formulas. In the assessment task, scholars apply estimation strategies to determine surface area in non-routine problems. They consider surface area of kitchen sponges, rock salt crystals, and...

Here's hoping that we can all fit into the pool. Given pictures and dimensions of a pool in tile lengths, scholars decide how many people can fit into the pool. This requires consideration of area, as well as the application of some...

Students explore the concept of estimation. In this estimation lesson, students estimate the number of Cheerios in their cup. Students then determine the number of Cheerios in the entire box using what they know about their cup.

Money doesn't grow on trees—it grows on walls. Using pictures of a Guggenheim art installation consisting of one-dollar bills glued to a wall, future mathematicians consider the monetary value of the bills used in the installation....

Unravel the mystery behind the infamous number pi. Scholars complete a series of activities that explores where pi comes from, its digits and estimation strategies. Pupils should be ready to measure, calculate, and look for patterns to...

Second graders explore estimation and place value. In this place value lesson, 2nd graders estimate and construct numbers while working with spider activities. Students use addition and subtraction to compare estimates. Resources and...

Students investigate the importance of significant figures through measuring and estimating. In this estimation and significant figures lesson plan, students measure pieces of paper and round their figures to the nearest marking on the...

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...

Young mathematicians explore integers. They review adding integers through engaging in mathematical labs. Each lab station is designed to reflect one of the multiple intelligences. Resources for all activities are provided.

Students apply estimation strategies and proportional reasoning to determine a scale comparing the planetary bodies to Earth. They convert measurements of time and distance using scientific notation. Both the metric and customary units...

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...

Learners explore the concept of boomerangs. In this boomerang instructional activity, students throw homemade boomerangs at different angles to record maximum distance and if it returned or not. Learners collect their boomerang data then...

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.

Third graders explore math functions by completing problem solving activities. In this division lesson, 3rd graders utilize the division strategies acquired earlier to divide multiple digit numbers by 4's. Students complete problems on...

Students discover scales for both the solar bodies' relative sizes and their distances from the sun. They find equatorial circumference and volumes of their solar bodies. Students apply estimation strategies and proportioanl reasoning to...

Jump at the chance to use the idea of rates. Young mathematicians watch part of a clip of a Japanese TV show where a contestant jumps rope as fast as possible. They use the data for the number of jumps and the number of seconds shown in...

Help pupils see the world through the eyes of a mathematician. As they examine tide patterns, sound waves, and stock market patterns using trigonometric functions, learners create scatter plots and write best-fit functions. 

Young scholars estimate and compare grapefruit weights. In this weight measurement and literacy lesson, students listen to the story Nate's Big Hair and the Grapefruit in There, then estimate the weight of a grapefruit after holding it....

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...
