In this Battle of Clontarf worksheet, students read about the battle, answer short answer questions, draw a picture, and estimate the population. Students complete 4 activities.

Fifth graders complete measurement problems where they use powers of ten, read metric measurement tools, estimate measurements, and more. For this measurement lesson plan, 5th graders complete 10 problems.

In this multiplication worksheet, students estimate the products in 19 problems in which two or three digits is multiplied by single digits. There are no examples or instructions on the page.

In this math worksheet, students make estimates to consider the possibility of each event taking place from impossible to likely.

In this geometry worksheet, learners measure various angles. First, they write what type of angle each one is, whether right, acute, or obtuse. Then students estimate the measurement and then write the actual measurement for each angle.

In this fractions worksheet, learners put fractions into their simplest form, write as improper fractions, add and subtract, estimate amounts, and more. They complete 31 problems.

Microbiology beginners feed different sweetening agents to yeast and measure carbon dioxide production to estimate energy contained in each. They set the trials up in zip-top plastic baggies and then measure gas volume by water...

Students research the HPV vaccine and estimate its cost. They interview doctors and local health officials about it. Students write feature stories based on their research focusing on the timelines for implementation in their states or...

Students investigate the concept of the number one million. In this number concepts activity, students read the book How Much is a Million? and brainstorm questions, such as "how many leaves are on a tree" and "how many hairs are on your...

Young mathematicians explore the maximun area for patio with the added complexity of finding the mimimum cost for construction. First, they maximize the area of a yard given a limited amount of fence and  plot width v. area on a...

Hook your class up to an online home energy usage calculator so that they can estimate the amount used per month by their families. Then give them Watt meters with which they will measure the power consumption of several small...

After a whole-class discussion of water reservoirs, ten liters of water are given to each lab group to represent Earth's total amount of water. They divide the water into smaller containers, each representing one of those reservoirs. The...

After calculating the amount of energy in a wave, future engineers plan and present to the class a design for a seawall that will minimize erosion on the shore. Not only must they consider the energy that will impact the wall, they also...

How much solar energy is available at my location? An engaging resource provides a presentation along with script to give the class background information on determining solar radiation. Pupils then work through a worksheet to...

Estimating a square root is as easy as evaluating a linear equation. Using the derivative of the square root function, pupils calculate an estimation of square roots. Class members determine the equation of the tangent line at the value...

Even though this activity is just a simple review of estimation, it is a fast and easy way to explore this topic. Young mathematicians estimate the number of items contained in two jars and discuss their answers. Afterwards, they can use...

Students make estimates and then measure leaves for accuracy. They calculate the area of the leaves by drawing an outline on graph paper and counting the squares. They compare the leaves exposed to sunlight to those that are in constant...

In this least squares activity, students solve 6 different problems that include the least squares of numbers. First, they plot 3 points on the axes shown and draw in their best approximating line. Then, students estimate the slope and...

Finding approximate solutions to word problems allows users to assess the reasonableness of their answers. In a well-paced lesson, the class rounds numbers to estimate the solutions. They explain their thinking and determine if the...

Students, using a list made up of things from around the room; estimate the distance of one of the items on the list with one unit, record their prediction, and then actually measure items with non-standard measuring devise.

Complete a lesson that introduces and explores operations with fractions and decimals. Pupils estimate the reasonableness of a decimal computation. Then discuss what operation is needed to find an answer. Handouts, web sources, and other...

Sixth graders estimate surface area of a pond using a random number table.

Young scholars create a survey to hand out to determine the best field day park. Using their local area, they select five parks, if possible, that meet the criteria and calculate the distance and estimated time travel. They use this...

Eighth graders view pictures that show many objects, estimate amount that they think they saw, and take class data from estimation to find the mean, median, mode, and range for the class.
