Problem Solving: Remainders in Division

Top of the Morning to You!

This problem challenges students to identify the 100th and 1000th letter that will be printed on the electronic signboard. To solve this, students will grapple with a division problem, figuring out how many letters are in the message and how many times the message will repeat to identify the 100th letter.  This is a good introductory problem because there are no remainders, making this a straightforward division problem. Nonetheless, students must explain their thinking and the process they used to solve the problem, so it's effective practice for state testing.
