Celebrating the One-Hundredth Day of School

In Politics the first hundred days is a sample of the first 100 days of a first term presidency of a president of the United States. It is used to measure the successes and accomplishments of a president during the time thattheirpower and influence is at its greatest. The term was coined in a July 24, 1933, radio address by US President Franklin D. Roosevelt, although he was referring to the 100 day session of the 73rd United States Congress between March9 and June 17, rather than the first 100 days of his administration.

In Schools another counting is taking place right now in American Primary Schools throughout the country to commemorate an event that happens every year: the onehundredth day of School. The count begins on the first day of school, when number lines and tallies begin, and counting sticks are placed in the 1s container. Culminating celebration activities abound as cereal, leaves, buttons, beads, and other everyday items are counted, sorted and placed in groups of 10, displayed, or mounted. (...)

'The 100th Day of School' by Angela Shelf Medearis:

(...) Now is the perfect time to bring out your favorite counting books, assess your collection, and add a few new treats to your shelves in preparation for this year’s celebration. It provides a great opportunity for reading a few counting books aloud and making a classroom or library display for children to enjoy.

A few books have been written specifically for this kind of celebration. Angela Shelf Medearis told this story about the beginnings of her book The 100th Day of School:
I was visiting a school when a tribe of first graders walked into the assembly wearing sashes and hats decorated with all kinds of odd things glued on them. The teacher was wearing a vest with 100 pennies glued all over it. I thought that maybe it was somebody’s birthday and asked the teacher. She told me that it was the 100th day of school. She was a first year teacher and I thought that maybe she was particularly happy to have completed 100 days! But, then she told me all about celebrating the 100th day of school and the counting and calendar activities teachers did. I knew immediately that I wanted to write a story about the 100th day of school to give teachers a tool.
