Last Digit Arithmetic
Mathematics involves a study of patterns. The exploratory lesson has learners consider the addition pattern in different sets of numbers. Each set has a different pattern that pupils describe mathematically. The patterns involve both...
Curated OER
Clock Arithmetic and Cryptography
Young scholars perform basic operations in modular (clock) arithmetic. Students encode and decode messages using shift and affine ciphers. Young scholars apply their multiplication, division, addition, and subtraction skills.
Curated OER
Modular Arithmetic Station
Eighth graders find ways to use math everyday. In this algebra lesson, 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
Modular Arithmetic on the Planet of the Eights
Young scholars explore modular arithmetic involving base eight. They participate in an activity where society functions around the numbers one through eight. Students explain how life will operate with only these numbers.
