Students estimate the live mass of dinosaurs. Using dinosaur and modern animal models, students use simple displacement methods to calculate the volume of the models. They calculate the masses of each model. Students compare the...

Students explore fractions. In this fraction lesson, students play an interactive game and use manipulatives to practice working with fractions.

Your young basketball players will build a table and develop a general formula for a decaying exponential scenario involving the rebound distance of a bouncing ball. Using a CBR and graphing calculator can make this even more hands-on...

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...

Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

Here is a nice lesson, which includes some good worksheets, on pumpkins and how they grow. It is an ESL lesson designed for beginning and early intermediate students. After listening to some books about pumpkins, learners label pumpkin...

Review and use standard units of measure with your math class. They move from station to station estimating and measuring length, volume, weight, and area. At each station they estimate and measure, and then compute the difference...

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...

Dividing decimals is not hard, but one has to know how to manipulate the decimal point in order to achieve correct answers. In this math presentation, learners are taken through the process step-by-step in a clear and concise fashion....

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...

Without measuring, can estimators determine which string is the longest? The shortest? There are two sets of strings here for learners to evaluate, circling the shortest in the first set and the longest in the second. Next, they eyeball...

Your young physicists analyze the forms of four equivalent exponential expressions representing an amount of a radioactive material in a substance. They show how each expression is equivalent to the others and what aspects of the decay...

What is your favorite animal at the zoo? Young mathematicians answer eight multiple choice questions, based on a survey of 50 people presented in a pie graph. Additionally, the graph does not display any numbers, but rather...

It is about this big. An assessment provides three questions on the estimations of volume. Pupils determine the quantities needed and use dimensional analysis to arrive at estimations involving dollar bills, paint, and gasoline.

It's all just a matter of time. The resource provides four Fermi questions in reference to time. The questions are open-ended and require classmates to make use of estimation and dimensional analysis.

This math worksheet requires self-assessment of personal feelings regarding mathematics. Beginner mathematicians rate themselves on various aspects of math as well as share what they feel to be their strengths and weaknesses in the...

In this estimating lengths worksheet, students observe problems with pictures and lengths and choose the length that gives the best estimate. Students solve 9 problems.

Here is a very good estimating and measuring length with nonstandard units worksheet. Learners use paper clips and toothpicks to estimate and measure the real objects pictured in each problem, then write ten answers.

Use this resource to teach perimeter of regular plane shapes, measurement, rounding, and systematic problem solving skills. There are 78 complete slides and two game suggestions intended to facilitate content understanding.

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...

Space science and math collide in this inquiry that investigates launching times for antacid-tablet rockets! Upper elementary or middle school learners collect data as they launch these mini rockets. They apply concepts of place value...

The square root of five and five do not have the same value! How many times have you addressed this with math classes? A lesson gives an explanation of a square root and gives examples for simplifying square root...

Our final proposal for the cost of the bridge requested is ... In the last segment in a series of 10, pairs work together to develop a proposal for a city bridge design. The class completes a cost comparison between concrete and steel to...

Scholars use formulas for the area of a circle and the area of a rectangle to determine the number of pies a baker can make from a particular area of dough. They must also take into account rolling the remaining dough into a new sheet.
