This is the Teacher by Rhonda Gowler Greene, illustrated by Mike Lester

From chapters.ca:
This hilarious cumulative tale in the tradition of "The House That Jack Built" depicts a typical day at school. This is the teacher all ready for school. These are the students who rush through the door and topple the teacher all ready for school. The chaos continues - and accumulates - on each spread. An ant farm is tipped over, the birthday boy slips and spills his cupcakes, and then the class hamster escapes.... Through it all, the stalwart teacher manages to keep her cool. But, boy, is she ready for bed at the end of the day! -
