Upper graders explore the topic of volume. In this math lesson plan, pupils count volume in cubic units, multiply to find volume, estimate volume, write a multiplication sentence to find the volume, and make a cost analysis of different...

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Develop a definition of irrational numbers through an exploration of square roots. The 11th activity in this series of 25 asks scholars to estimate the value of a square root. Learners observe as the estimation extends further and...

Second graders choose estimation strategies in real-world problem situations and explain the choice. They work in groups of five using three different estimation methods to find out how many words are on a page of text.

Students practice multiplication playing a game. In this multiplication lesson plan, students pick numbers and multiply them together. Students are awarded points based on which "hive" their answer falls in. The student with the...

Fourth graders visit a real pond. They mark the pond's curvilinear perimeter using string. They measure the string to find the actual perimeter of the pond.

Fifth graders practice solving problems.  In this fraction and decimal lesson, 5th graders recognize the relationship between fraction and decimals.  Students estimate problem results and write expressions to use for problem...

Students use estimation as a math strategy. Students estimate the number of small snacks that are presented to them. Students count the snack items after they have estimated how many there are, before the class snack on a daily basis.

In this estimating quotients worksheet, learners solve 20 different problems that include estimating a variety of quotients in each. They divide each whole number and then estimate the answer in each problem to the nearest whole number.

Students analyze a multi-seeded fruit, such as tomato, pepper, squash, watermelon, etc. They remove and count the seeds from the fruit and hypothesize/calculate the reproductive rate of that organism.

Fourth graders use number facts to estimate quotients. In this division lesson plan, 4th graders examine long division problems to determine which multiple of ten will help them determine a number that is close to a quotient. They adjust...

In this multiplication learning exercise, students solve 40 problems in which two and three digit numbers are multiplied by single digits. Students are encouraged to use estimation to do mental math. This page is intended as an online...

Fifth graders look at the Garrison flag and estimate how big it is. In this measurement lesson plan, 5th graders then calculate the area and perimeter of the flag.

Students investigate various types of problems using whole numbers and decimals. They use a discussion format while working example problems to help create a baseline for further independent practice. The lesson plan also includes praise...

Students use coupons to save. For this saving lesson students practice their addition, multiplication and estimating skills with dollars and cents. They investigate grocery coupons and look for ways to save money.

Third graders use base-ten blocks to find products of two-digits by one-digit by making a model of the problem. They complete a worksheet by multiplying 2-digits by 1-digit with regrouping. They may use the base-ten blocks if needed.

Learners solve word problems using number sense. They convert fractions to decimals and mixed numbers. Pupils determine if a given fraction is greater or less than another fraction, and order numbers on a number line.

Come take a ride on the space bus! Scholars go on an imaginary trip to pick up their peers from the inner and outer planets while reinforcing math skills. First, learners round decimals to identify each planets' distance from Earth....

How do you operate with numbers in scientific notation? The resource provides examples on how to divide and multiply with numbers written in scientific notation. The handout and video also cover the procedure for addition and subtraction...

You can't evaluate an irrational root expression without a calculator—or can you? Scholars estimate the value of roots within an expression to approximate the value of the expression. Expressions include a mix of square roots and whole...

In this integers worksheet, learners solve and complete 8 various types of word problems. First, they read each problem and determine from the information what they are looking for. Then, students determine the operations necessary to...

Reinforce math vocabulary with a set of flashcards. Twenty-two cards offer either a bold-faced word card or a corresponding definition card equipped with an example and labels. Terms include factor, repeating decimal, unit fraction,...

Students explore the concept of Pascal's Triangle. In this Pascal's Triangle lesson, students use an applet called 'Coloring Multiples' to explore Pascal's Triangle. Students develop patterns starting with various numbers in Pascal's...

Sixth graders practice creating and solving number sentences on a calculator. They interact with number facts, their properties, algorithms and estimation. Each student recognizes inverse relationships of addition, subtraction,...
