In this third exciting entry to the chapter book series that covers STEM topics with Flat Stanley and his friends, Stanley must decide what to bring to Classroom 2E’s Hundredth Day of School bash.
Ever since Stanley Lambchop was flattened by a bulletin board, each day brings new adventures!
It’s the 100th day of school, and the second graders in Classroom 2E will each be bringing 100 of something to celebrate. Stanley knows exactly what he wants to bring—flat pancakes! But now, his best friend Marco is ignoring him and the number of people coming to the party keeps changing.
Stanley must add, subtract, and multiply his way to the perfect treat for the Hundredth Day of School bash. Will he get the numbers right?
