Grade Level 5th



A timeline or chronology is a way of ordering events. For example, if you wanted to make a chronology of your family, you would begin with who was born first. Then, who was born second, third and so on. The chronology of my family would look like this:

1918 – Cruz Floriano Rios (my dad)

1920 – Lucy Esther Rios (my mom)

1952 – Valentine Rios (me)

1954 – David Rios (my brother)

1955 – Conrad Rios (my brother)

1958 – Marta Rios (my sister)

A chronology can be made for many things. In school you have probably seen a chronology of important dates for the history of our country or important dates for the history of the state where you live. A chronology can help us see and understand important events in the order when they happened.

Below is a chronology of the WWII 10th Mountain Division. It begins with 1940, the year in which an important member of the National Ski Patrol, Minot Dole, encouraged President Roosevelt to create a division of mountain soldiers. The chronology ends in 1945 when the division was inactivated, which is another way of saying the division was finished.

Objectives: 1) to introduce the student to the term chronology and how they are used. 2) to acquaint the student with a chronology of the WWII 10th Mountain Division. 3) to order selected events and pictures of the WWII 10th Mountain Division utilizing the chronology presented.
