Maintain a positive atmosphere in your math class with this fun lesson on adding and subtracting integers. After first explaining the rules for combining positive and negative numbers, this resource uses a comic strip...

Is it possible to add infinitely long decimals? As pupils complete the examples in the ninth lesson plan of this 25-part series, they determine that adding these decimals cannot be done without error. Their task is then to determine the...

Squares can be magic. Pupils use their knowledge of addition of positive and negative rational numbers to create a 3 X 3 magic square where the sums are 1. Scholars create addition and multiplication expressions with a set of rational...

An informative module highlights eight polynomial concepts. Learners work with polynomial functions, expressions, and equations through graphing, simplifying, and solving. 

Early learners rotate to different classroom centers and participate in six activities based on using marshmallows to review concepts learned. They make: marshmallow sculptures (geometric shapes), the shape of mittens using colored...

Add, subtract, multiply, and divide fractions with a worksheet designed to give your learners practice performing fraction operations. 

Mathematics involves a study of patterns. The exploratory lesson has learners consider the addition pattern in different sets of numbers. Each set has a different pattern that pupils describe mathematically. The patterns involve...

An interactive challenges mathematicians to add mixed fractions with unlike denominators. Five questions—fill-in-the-blank and multiple-choice—build from one to the next leading the way to an open discussion about denominators and...

Have your pupils practice basic addition and subtraction skills using this presentation in a game format. Learners add and subtract large numbers and answer word problems. This is a great way to review these concepts.

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...

All of these fraction pairs have common denominators, so adding them up is a bit simpler. There are two examples demonstrating both a mixed number and reducing to simplest terms. Scholars add up 28 fraction pairs, simplifying when...

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...

Give mathematicians 39 chances to practice adding fractions, most of which involve mixed numbers. There are three examples to get them started, and scholars should be encouraged to reduce answers when necessary. Not for beginners, these...

How can art represent math? Use a lesson on place value collages to illustrate the different meanings that numbers have in their designated places. Kids observe photographs and paintings that show place value, then work on their own.

Doubling a network or combining two networks is quick and easy when utilizing matrices. Learners continue the network example in the second lesson of this series. They practice adding, subtracting, and multiplying matrices by a scalar...

And they're off! Working in pairs, young mathematicians roll dice to see who can fill in their double ten-frames first. When learners finally fill in their arrays, they create addition number sentences that represent their rolls, helping...

Track down the Cyberchase episode that this lesson is associated with. Using a worksheet that is embedded in the plan, learners must find the next two numbers and shapes (a double pattern). Once these have been discovered, pupils try...

Have crumpets with the queen! Kindergartners count the number of crumpets on each plate - all add up to six - and write the correct number in the space provided. They then copy a dominoes pattern for different ways to add up to six, and...

Thirteen steps make up a lesson that challenges pupils to compare and contrast the daily lives of Pilgrims and the Wampanoag tribe. Learners revisit the Graffiti Wall then break into small groups for an investigative reading assignment...

Scholars examine the first Thanksgiving through books and interviews while they complete a KWL chart. Pretending they are part of the feast, learners craft a scrapbook page that features images related to their experience. Pupils reflect...

Middle and high schoolers complete and solve 12 various types of problems. First, they express the output as a function of the input in each table. Then, pupils evaluate for the given variable when the value is as stated. In addition,...

Each slide contains a group of animals and an equation that adds up to 10. However each equation is missing a number, learners attempt to determine the missing addend to revile the number of animals hiding under the cloud. A fun,...

This is a great math station partner game! Using the provided ten-frame cards, learners practice creating addition problems with a sum of 5. Each card has a number between 0 and 5, and pairs shuffle and lay out five of them. They take...

How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...
