Rational Expressions
Demonstrate the progression of operations with rational expressions through a multi-day lesson, equipped with worksheets for each day. High schoolers develop the concepts needed to perform operations with rational expressions. They learn...
Curated OER
Simplifying Square Roots
Discuss the definition for a simplified form for a square root. Middle schoolers analyze different forms of a square root, the Product Property of Square Roots, and complete a worksheet.
Curated OER
Operations with Fractions and Decimals
Complete a lesson that introduces and explores operations with fractions and decimals. Pupils estimate the reasonableness of a decimal computation. Then discuss what operation is needed to find an answer. Handouts, web sources, and other...
Curated OER
Introductory Algebra Chapter R Review
In this math worksheet, students solve the problems and simplify the fractions. Each of the sets is related to the instructional objectives.
Curated OER
Factors and Multiples
Sixth graders need to see the relevance in the mathematics they learn. This lesson builds on the concepts of least common multiple and greatest common factor. The lesson presents real-world problem situations for students to solve.
Curated OER
Patterns in Pascal's Triangle
Young scholars examine the patterns that exist in Pascal's Triangle. They explore multiples and factors. Sudents use an applet to create and color the multiples in Pascal's Triangle.
Curated OER
Clock Arithmetic and Cryptography
Students perform basic operations in modular (clock) arithmetic. Students encode and decode messages using shift and affine ciphers. Students apply their multiplication, division, addition, and subtraction skills.
Curated OER
Pascal's Triangle
Middle schoolers study Pascal's triangle. They construct their own version of Pascal's triangle, and relate some of the uses for it. While working through this process, students practice their integer multiplication and division skills.
Illustrative Mathematics
An Integer Identity
Challenge algebra learners to use the difference of cubes to solve this problem. Once your charges have taken out the factor (a - b), combined the like terms and set them equal to zero, the problem becomes a factorable quadratic...
