Why Lesson Planet?
Students are introduced to modular mathematics. They start by making clocks for different bases. They use their clocks to count, using the base, and then finding the mod or remainder. They explore both positive and negative numbers with their clocks. They use the lesson's applets to check their answers. They get more practice with modular mathematics by reviewing addition, subtraction and solving equations, and by finding the mod of the answers using more applets.
