March of the Dividing Ant
Students inspect divisibility rules. In this divisibility rules instructional activity, students study the relationship between factorization and the divisibility rules for 2, 3, 5, 6, 9, and 10. Students read One Hundred Hungry Ants and...
Curated OER
Pascal's Triangle
Young scholars 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.
Curated OER
Polynomial Divisions
Young scholars factor polynomials and use long division t solve problems. In this algebra lesson, students find the zeros of polynomials by synthetic and long division. They perform operation using complex numbers.
Curated OER
Arithmetic Complex Numbers
Students convert quadratic functions from standard form to vertex form. In this algebra lesson, students solve polynomials using synthetic and long division. They derive and apply the remainder theorem and factor theorem.
Curated OER
Modular Arithmetic Station
Eighth graders find ways to use math everyday. In this algebra activity, 8th graders model equation and problem solving as they multiply and divide numbers. They split up in to groups as they perform hands on operations.
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.
