Begin the school year right with this great classroom management aid. Children learn their mailbox number and place their products into their correct cubbyhole, saving the teacher valuable minutes each day. DIRECTIONS: Assign each student a mailbox number, and then have each child rainbow write their cubbyhole mailbox number on their personalize worksheet. Even if a child can not yet write their name, with this worksheet, they can learn to write their mailbox number onto the top, right corner of all their pages for the rest of the year. If a paper ever gets misplaced, any student can correctly place that paper into the correct cubbyhole. BONUSES: (1) Using a number system for a class allows papers to easily be ordered for grading and redistribution. (2) There is also a blank page at the end of the pdf file for various uses such as Valentine's Day paper bag decorating. (3) The shapes on the mailbox are ordered from a 3-sided triangle to an 8-sided octagon to reinforce students' recall as they identify and describe geometric shapes. Enjoy those extra hours you save this year and thanks for downloading for improved classroom sanity!
