Multiplying Improper Fractions

CC_BY-NC-SA

Instructional videos for multiplying mixed numbers/improper fractions. The intent is NOT to share the most efficient, compact way to multiply. The point is to make sense of multiplication. Part 1 - multiplying two digit whole numbers in context. Part 2 - multipying mixed numbers using the idea from Part 1

NEW and IMPROVED Division of Fractions

CC_BY-NC-SA

A NEW and IMROVED division of fractions activity designed to develop the...do I have to say it..."Keep Change Flip"...algorithm.  Includes student pages, teacher pages (with answers and description of the intended thinking) and a Smartpen pencast where I provide an overview/example of the intended thinking. Note that the pencast document comes in the form of a PDF - check out this for details as you need a PDF reader like Adobe Acrobat X in order to view the pencast. -http://www.livescribe.com/en-us/faq/online_help/Maps/Connect_Desktop/c_viewing-and-playing-a-pencast-pdf.html

Fractions and Free Throws

CC_BY-NC

Do we always add fractions by first finding a common denominator, etc.? Or, could it make sense to add two fractions by adding the numerators and denominators? This activity explores these questions.

Can We SWIM Yet?

The Johnson family is SO excited to go swimming in their new pool! Which of the three hoses should they use to fill it the most quickly? How long will it take to fill if they use all three of the hoses?

Fraction Operations and Initial Decimal Ideas

CC_BY-NC

This is a series of lessons from the Rational Number Project (http://www.cehd.umn.edu/ci/rationalnumberproject/rnp2.html) including teacher notes, activities ready to be copied. The Rational Number Project (RNP) is a cooperative research and development project funded by the National Science Foundation. Project personnel have been investigating children’s learning of fractions, ratios, decimals and proportionality since 1979. This book of fraction lessons is the product of several years of working with children in classrooms as we tried to understand how to organize instruction so students develop a deep, conceptual understanding of fractions. You may pick and choose the lessons that you would like to try and do not need to complete them all in order.
