Keep track of when students forgot to turn in their homework with a Yikes slip. Yikes slips are a more positive way to track missing homework. Yikes stands for "Yikes I forgot my homework," emphasizing it's okay to make mistakes. Students fill out both sides of the Yikes slip. Then they cut on the dotted line. They bring the larger portion home staple it to the missing homework and have their parents sign it. You keep the smaller receipt portion for data collection. I like to keep my smaller portions on a Wanted Poster hanging up in my room. As in "your homework is wanted by me!" When students complete the assignment, they return it with the signed Yikes. I send those home. I keep the receipts in the students' files so that I can keep track of which students have a homework completion problem.
