Pupils use clock arithmetic to find remainders. In this patterns in math lesson, students explore the relationship between clock arithmetic and remainders using a computer applet. Pupils also identify patterns in Pascal's triangle with...

Learners explore the concept of modular arithmetic and cryptography. In this modular arithmetic and cryptography lesson, students use applets to explore modular arithmetic using a clock and Caesar Ciphers. Learners exchange their ciphers...

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.

Students will explore modular arithmetic in this activity. The student will set a starting value and them move the "clock" forward a number of specified hours to see the resulting sum. Included are disucssion resources, additional...

Introduces students to modular (clock) arithmetic and its uses in real world problem-solving.
