Creating Calendars in Pre-Algebra
Pre-Algebra Class for Level 7 students finds itself in the middle of a unit studying factors, fractions and exponents. First, the class learned about specific divisibility rules. Next, they explored and acquired more details about the use of exponents. Currently, the class is learning prime factorization and finding the greatest common factor. The project they completed for this unit involves investigating the ancient Egyptian calendar to understand why the Egyptian calendar was based on 360 days rather than 365. After analyzing our current calendar, students determined how leap years come into play. Finally students were asked to design and create their own calendars. They used their knowledge of factors and multiples to divide their calendar into different periods. Drawing on their graphic understanding of mathematics, they came up with everything from graphs, tables and number lines to circle calendars.
