Product Description
Students erroneously think that multiplication always "grows" numbers, and division always "shrinks" things. Using this calculator exploration, students examine the effects of various operations on decimals, namely, that multiplying by numbers less than one actually "shrinks" things, and dividing by numbers less than one actually "grows" things. This is quite an epiphany in the world of number sense! A warm-up provides a strategy for students before they attempt the A-MAZE-ING DECIMALS PUZZLE on page 2. Page 3 includes a lesson plan with teacher tips, and page 4 provides a sample "path" through the puzzle. There are so many possibilities with this puzzle that I haven't provided an answer key - will you do me the honor of posting your students' highest and lowest scores in my "feedback"? Thanks!
