PRODUCT DESCRIPTION

Make time to have fun in math class!

This is one of my favorite math approaches. Though it doesn't tie specifically to one CC standard, I've found it beneficial to students in several ways. I've always used the strategy of being able to half numbers mentally in my classroom.

Being able to half numbers mentally is a worthwhile skill (aka lifehack) to develop for these and other reasons:
*making estimates
*judging the reasonable of answers
*recognizing the relationship between multiplication and division
*finding patterns
*working comfortably with multiplying fractions

This resource is a collection of over 50 video clips embedded in a powerpoint. Just click to play the clips, and this works as a great Around the World activity. An expression will be revealed which requires a student to half a number. As seen in the picture above, the expression may be written in several formats, but any way it's given, they gotta half it!

As with all my resources, this file has been kid-tested and created by me, a veteran teacher dedicated to the philosophy of promoting math fluency and skill mastery through fun!

Thanks again!

Sincerely,
Madison

(A side note re: classroom management) While some teachers may count down from 10 or 5 to quiet their students for a transition, I might start with 64, then do 32, 16, etc and have students raise their hands signalling they're ready to supply the next term. Or, if I want them to turn to page 48 in a book, I might begin with a halfing pattern that eventually will stop at 48, just so they will all be with me and ready to start at the same time.
