Twenty-eight flashcards make up a set designed to reinforce math vocabulary. Two styles of cards showcase either a bold-faced word or a corresponding definition card equipped with an example and labels. Terms include commutative property...

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

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,...

Add some randomization into simulations. The 11th installment in a series of 25 presents two new methods to use in simulations--colored disks, and random numbers. Pupils use random numbers to run simulations where the probabilities make...

Support math vocabulary using a set of 25 flashcards. The set consists of a variety of bold-faced word cards and corresponding labeled picture cards. Terms include even numbers, regrouping, skip counting, and more.

Five questions—multiple-choice, fill in the blank, and discussion—make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians...

Work it out — find the average time clients spend at a gym. Pupils use a table of random digits to collect a sample of times fitness buffs are working out. The scholars use their random sample to calculate an estimate of the mean of the...

Assess scholars' knowledge with a 22-page assessment that covers place value, patterns, probability, estimation, measurement, geometric figures; and their ability to add, subtract, multiply and divide proficiently. 

Develop a better understanding of the value of pi. Learners explore the area of a circle using estimation and graph paper. While continuing to estimate the area of the circle using smaller and smaller grids, the number pi emerges. 

Young mathematicians learn how scientific notation is meant to save time. Part 10, out of a series of 15, asks scholars to recognize the correct use of scientific notation and finish by adding and subtracting numbers using...

The class braids irrational numbers, Pythagoras, and perimeter together. The mini-assessment requires scholars to use irrational numbers and the Pythagorean Theorem to find perimeters of rugs. The rugs are rectangular, triangular,...

It all adds up to one. Pupils solve several items that involve finding sums of fractions in relationship to a whole. The assessment task uses fractions with unlike denominators to determine the amount of a tank of gas and the amount of...

For kids, taking a vacation is all fun and games, but after completing this pre-algebra project, they'll have a whole new appreciation for the planning that makes these trips possible. Given a budget of $5,000 to spend on purchasing the...

Sometimes dealing with decimals is so much easier than dealing with fractions. The ninth lesson in a 21-part module has the class consider situations when it might be easier to add or subtract fractions by first converting to...

Was there a baby boom? Using census data, class members take a look at the number of 8-11 year olds and determine their birth years. Scholars create a double line graph to compare the number of births for two states for several years....

Are the means the same or not? Groups create samples from a bag of numbers and calculate the sample means. Using the sample means as an estimate for the population mean, scholars try to determine whether the difference is real or not.

Boiling down any division problem to a one-digit divisor problem sure makes estimation easy. The lesson shows how to estimate division problems by using place value understanding and basic arithmetic facts to simplify the division. Some...

Class members explore the estimation of irrational numbers in association with the Pythagorean Theorem. The first lesson of this module challenges pupils to use the Pythagorean Theorem to find unknown side lengths. When the length is not...

Congratulations, you've just hit the word problem jackpot! Covering an incredible range of topics from integers and fractions, to percents, geometry, and much more, this collection of worksheets will keep young mathematicians...

Captivate your class by having them find the value of their names, different zoo animals, musical instruments, etc.,with a mental math lesson. Using the coding formula listed, children learn to fluently estimate and calculate...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Over the course of five periods, scholars create a poetry portfolio. They begin with a reading of the poem, Firefly. With a focus on vocabulary, learners reread the poem then look for sight words and other skills. 

When is it a good idea to use estimation? Learn about estimation and rounding with a reading comprehension lesson. After kids read a passage about estimation, they answer five comprehension questions on the other side of the page.

Teach your class a thing or two about making educated mathematical guesses. Learners read a passage that explains estimation and approximate and exact answers. They then respond to five questions about and related to the text.
