Scratch for Elementary 100th Day of School

Here is a great project to do with early elementary students for the one hundredth day of school.

Programming concepts:
Variables (variables are a place to remember things, and keep track of things)

If students have not yet learned about variables, talk about things they remember and count:
* Tell them a simple story like this:
I would like to tell you about something. Did you know my favorite food is chocolate?
One day I was hungry, so I went to the store, and bought bread, lettuce and turkey. I put the lettuce and turkey on a piece of bread. I put another piece of bread on top. I ate the sandwich.
I ate my favorite food for dessert. What did I eat for dessert? * Ask them to count to twenty. Stop them several times along the way. Then let them continue. How did they know what they next number was? (they remembered, it was in their brain.) Suggest that a variable is like the place in the computer that remembers numbers or important words like “chocolate.”

Programming concepts:
Iteration
Repeat
(repeat blocks are one example of iteration in programming.)

If students have not yet learned about iteration, talk about things they do over and over:
* You turn the pages of a book ***until*** you come to the last page
* You walk towards your desk ***until*** you reach your desk, then you sit down.
* You answer each math problem on the worksheet ***until*** you have done all ten problems
