CONTENT STATEMENT
- Events can be arranged in order of occurrence using the conventions of B.C. and A.D. or B.C.E. and C.E.
CONTENT ELABORATION
In grade four students learned the use of single-tier timelines.
Grade-five students build on the use of single-tier timelines by becoming familiar with the two systems used to identify dates on the commonly used Gregorian calendar (also known as the Christian or Western calendar). It is not necessary for students to study the origins of calendar systems, but to recognize and be able to use the terms B.C. (Before Christ), A.D. (Anno Domini), B.C.E. (Before the Common Era) and C.E. (Common Era) to place dates in chronological order.
Arranging events in chronological order on single-tier timelines using B.C.E. and C.E. or B.C. and A.D. requires students to understand that years in the B.C.E. or B.C. era are labeled following the conventions of negative numbers beginning with 1 B.C.E. (there is no year 0).
EXPECTATIONS FOR LEARNING
Apply the conventions of B.C.E. and C.E. or B.C. and A.D. to arrange and analyze events in chronological order.
