Numbers and Operations Lesson Plans

Students solve problems with complex numbers. In this algebra lesson, students factor complex numbers and simplify equations using DeMoivre's Theorem. They add, subtract, multiply and divide using negative roots.

Sixth graders identify prime and composite numbers and complete an activity problem. Given a 100 chart, they follow directions to create a prime number chart. In groups, 6th graders play a "Prime Take Away" activity to reinforce prime numbers.

Second graders review the basic concept of place value and practice making groups of ten. Using math sentences, they identify and place the correct addend to make it complete and true. They also discover the pattern created as groups of ten are made.

Students apply number and operation skills to learn how to spend a gift certificate. In this mathematical reasoning lesson, students use base 10 blocks as money and calculate how much money they have.

Third graders explore place value to the ten-thousands place. For this amazing, 21-page place value lesson, learners represent numbers in standard and expanded form, and use technology to represent numbers to 9,999.

Students create number charts based on the book and complete other worksheets demonstrating the use of decimals and fractions.

Third graders understand the economics of choices in buying. In this goods and services lesson, 3rd graders participate in activities to make choices about purchases. Students write stories, answer questions, and complete worksheets to increase understanding of economics.

Fourth graders read and share chapters of The Boxcar Children. For this wants and needs lesson, 4th graders understand through their reading the differences between wants and needs. Students complete a worksheet about wants and needs based on the book.

Students investigate mathematics as it relates to the real world. In this algebra instructional activity, students solve quadratic equations and graph their results on a coordinate plane. They model quadratics and apply  the quadratic formula to solve equations.
