Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into what it...

Develop mental math addition skills by breaking apart addends into 10s and extras. Worksheet has problem solving steps at the top of the page, and 8 practice exercises that lead to increasing independence using the process. 

Exercise those mental math muscles! This worksheet contains 10 addition and 10 subtraction problems which require learners to compute sums or differences in their heads. A quick review at the top of the page provides a strategy based on...

The 10th lesson in a series of 32, continues with the geometry of arithmetic of complex numbers focusing on multiplication. Class members find the effects of multiplying a complex number by a real number, an imaginary number, and another...

Young mathematicians construct their own understanding of integers with an inquiry-based math lesson. Using colored chips to represent positive and negative numbers, children model a series of addition and subtraction problems as...

Time for matrices and complex numbers to come together. Individuals use matrices to add and multiply complex numbers by a scalar. The instructional activity makes a strong connection between the operations and graphical transformations.

Use a function to operate on two variables. Pupils look at operating with complex numbers as a function of two variables. The interactive squares the input and adds a constant to it. Learners visualize the resulting output and its...

Have some fun building squares out of triangles. Pupils investigate the partial sums of odd numbers. Using the sum of the first four odd numbers, learners see that it can be rewritten as a sum containing a triangular number. Simplifying...

Pupils practice rounding numbers to the nearest ten and hundred. They solve rounding numbers word problems, and add and subtract rounded numbers. This nice, neat handout fully serves its purpose and can help meet CCSS.Math.Content.3.NBT.1.

Try a new approach to addition and subtraction by giving scholars the numbers but leaving out the sign. They must determine if the numbers have been added or subtracted, then write in the appropriate operation. There are a few examples...

What do animated videos have to do with mathematics? Using operations of complex numbers and their representations on the complex plane, high schoolers observe how mathematics could be used to move animations. The lesson...

What is the meaning of sea level? This resource helps your class understand the meaning of elevations above, below, and at sea level. Provides for good discussion on using positive and negative numbers to represent quantities in the real...

The nth roots of unity all have a magnitude of one. Scholars use the unit circle and DeMoivre's Theorem to find the complex roots of one and discover that the complex numbers all lie on the unit circle and are equally spaced around it...

An excellent way to review math ten frames, this series of posters reminds kids how to mark numbers 11-20. Each pages features a ten frame with the first ten spots filled out to indicate 10, then additional frames to indicate how many...

The ninth part in a 25-part series emphasizes the importance of using properties of operations in evaluating sums and differences of rational numbers. Pupils solve problems and provide justifications for each step.

Rather than a worksheet, this teacher resource is a one-page, scripted answer sheet for a guided lesson on the addition of numbers under 100. While the pupil handout is missing, the teacher guide could be reformatted for classroom use.

Although this learning exercise says it contains addition and subtraction within 20, it doesn't. Learners will have to add and subtract double-digit numbers with answers up to at least 30. However, it does provide good practice.

For this math worksheet, students solve 100 problems in which 2 digits are added to one digit numbers. Example: 44 + 9. Problems are written in a vertical format and are closely spaced.

In this understanding whole numbers worksheet, 4th graders use a computer program for instruction, then answer 16 problems about addition and subtraction.

In this adding mixed numbers worksheet, students add mixed numbers with uncommon denominators. Students complete 9 problems total.

In this mixed numbers worksheet, students practice adding mixed numbers together. Students complete 4 problems where they add mixed numbers.

In this fraction activity worksheet, students play a game that require them to add using fractions and mixed numbers. Students respond to 3 questions regarding the problem solving skills used in the game as well. 

In this multiplication learning exercise, students multiply one digit numbers by two digit numbers and three digit numbers. Students complete 28 problems.

In this mixed numbers worksheet, students add mixed numbers with like denominators. Students complete 7 problems on 10 pages total.
