Centuries, Decades and Elapsed Years, 1600 to 1877

Review the box with the class before students begin. On the chronology sheet, check the first age problem together.

Name centuries and decades and subtract years and ages for events from Jamestown to Gettysburg. The directions on the page read: Read the box. Name the century (1, 3) or decade (2, 4). Show the subtraction in 5 to 10. Then answer 11 to 14. An answer key is included.

Yes, both. We made it for 8th grade Sources, Data and Research Skills, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

A fact can be checked and shown to be true or false. An opinion is a feeling or belief that cannot be proven. The Shays' Rebellion sheet adds a third kind, the reasoned judgment, which is backed by evidence.

The 15th century is 1401 to 1500, often called the 1400s. Students use this rule for events such as Jamestown in 1607.

Subtract the birth year, and take away 1 more if the birthday has not come yet. The worked example on the page finds John Adams's age on July 4, 1776.
