Once scholars have a grasp on adding fractions, it's time to throw some mixed numbers into the equation! Each of these 14 addition problems has one mixed number and one proper fraction. Skills here include finding a common denominator,...

Once your mathematicians can add two-digit numbers, it's time to bring on the three-digit addends. Here are 20 practice problems, each involving two whole-number addends. Learners do not need to regroup for any of these, and they have...

Test your third graders with a math review instructional activity, which features problems on square numbers and area. After finding the squares of increasingly large numbers (3-40), pupils solve for the areas of six squares. A great way...

Using the six word problems provided, learners practice adding and subtracting mixed numbers. They help Jose, Sasha, Juanita, Stephanie, and Carlos to solve their problems!

Addition and subtraction are essential skills for all young mathematicians. Explain the step-by-step process with respect to place value using these real-world examples. Focus is on numbers in the tens, hundreds, and thousands, making...

In this Christmas theme addition worksheet, students add single-digit numbers to five, write the addends, and find the sum. Students write and solve addition sentences.

An outstanding PowerPoint presentation on two-digit addition with regrouping awaits your class. The slides present the steps necessary in extremely clear fashion. There are two "internet games" embedded in the final slide that lead to...

Show scholars that if they can add two multi-digit numbers, they can add four! They complete 20 practice problems adding three and four-digit numbers. All the equations have four addends and include units. All numbers are whole numbers....

As learners become familiar with counting, it's helpful to use worksheets like this one to focus on just a few numbers at a time. Scholars begin by tracing the numbers 17 and 18, then print each numeral once on their own. Next, they...

You'll never be out of subtraction worksheets again. Here are 11 different sheets that require learners to add or subtract to find sums or differences up to or less than 20. Perhaps these can be used at home, at a work station, or to...

As an assessment or worksheet this resource has 10 versions of adding and subtracting negative numbers. Each version comes with two options, one with an answer choice box and one without. Let this resource do the work for you when...

Scholars investigate the concept of adding positive and negative numbers. They practice adding using the number line for scaffolding. This can be done as a game for younger learners, but may also be helpful for engaging the older pupils.

Guide young mathematicians through the crazy world of negative numbers with a handy reference document. Offering clear instructions for adding and subtracting positive and negative integers, this resource is a great way to...

Help the class visualize operations with complex numbers with a lesson that formally introduces complex numbers and reviews the visualization of complex numbers on the complex plane. The fifth installment of a 32-part series reviews...

Are complex numbers and binomials similar? This stack of slides provides an introduction to complex numbers and shows how to operate with them. The worked examples show a connection between operating with binomials and operating with...

As penguins jump off of an iceberg, young mathematicians count the remaining penguins in order to discover the whole number subtraction answer. As they work through the questions, they can manipulate the red dot to add and subtract more...

Practice adding whole numbers by combining the amount of fish Alice and Bob catch. As young mathematicians work through each problem, they are asked to find one more plus the amount of fish already caught. They can manipulate the...

Represent complex numbers in two ways. Pupils use the interactive to convert polar and rectangular representations of complex numbers. The learners drag an overlay back and forth over the coordinate plane to reveal the polar coordinates...

Challenge mathematicians to crack the binary code with an interactive that focuses on numbers nine to 16. A table reveals exponential equations to aid in answering multiple-choice questions. A discussion question gauges comprehension. 

Try out a resource using triangles to estimate radicals. An interactive app allows learners to approximate some irrational numbers involving square roots. They find the two consecutive numbers that an irrational number lies between...

Get real about learning the real number classification. Young mathematicians create a graphic organizer of the real number system using an interactive. They answer a set of challenge questions on the classifications of real numbers.

A six-question interactive tasks scholars with adding binary numbers one through eight. A tool acts as a visual aid to showcase the patterns made when working with base—2, digits zero and one. Question types include fill in the blank,...

In this pre-algebra addition and subtraction of fractions and mixed numbers worksheet, students add or subtract fractions in the first 10 problems. They write the answers in simplest terms. They add or subtract mixed numbers in the last...

Adding and subtracting mixed numbers need the same attention that regular fractions do by finding a common denominator. If you plan to use a vertical line-up of the fractions then this video is for you. It just introduces this method, it...
