This book is a fun way to review previously learned multiplication skills.

Elementary students are used to seeing multiplication as a way to get more of something. Create a T-chart and brainstorm situations from the text when more objects resulted and when less objects resulted. Use the book as a guide. Discuss what kind of numbers Rumpelstiltskin and Peter multiplied by to get more and to get less.

Including these problems with whole numbers in the primary grades lays the groundwork for developing an understanding of multiplication and division of fractions in later grades. ]]> 2016-10-31 04:32:16 UTC https://padlet.com/ariananwoods13/mvr0impjpg4a/wish/134137126 ariananwoods13 https://padlet.com/ariananwoods13/mvr0impjpg4a/wish/134137724 2016-10-31 04:43:07 UTC https://padlet.com/ariananwoods13/mvr0impjpg4a/wish/134137724 ariananwoods13 https://padlet.com/ariananwoods13/mvr0impjpg4a/wish/134138270 Writing Equations with Multiplicative Comparison Problems
Things to remember:
1. Multiplicative comparison means you are comparing two things together that need to be multiplied.
2. An equation is just like a number sentence but it includes letters.
3. The letter is called a variable.
Examples: 
1) Suzie is 4 feet tall. There is a tree in her yard that is 9 times taller than she is. How tall is the tree in Suzie's yard?
2) The tree in Suzie's yard is 36 feet tall. The tree is 9 times as tall as Suzie. How tall is Suzie?
3) Suzie is 4 feet tall. The tree in her yard is 36 feet tall. How much taller is the tree than Suzie?]]> 2016-10-31 04:56:29 UTC https://padlet.com/ariananwoods13/mvr0impjpg4a/wish/134138270 ariananwoods13 https://padlet.com/ariananwoods13/mvr0impjpg4a/wish/134138612 Ask students would they rather have $10,000 dollars right now or receive one penny today and double it every day for 30 days? Ask them to explain their answers. Tell them you think they may change their mind after they hear the story you are going to read about doubling in mathematics!
