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...

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.

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. 

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...
