App of the Week: Virtual Manipulatives

What is it?
This app is a a set of fraction bars to be used with students.  This app is meant to be used with direct teacher instruction, and give students the opportunity to interact with fractions, decimals, and percents right at their fingertips.   They are able to drag fraction bars on to their workspace, press and hold on a fraction bar to see an equivalent, as well as draw or show work using their finger and the pencil tool. This is a great tool for visual learners to see how fractions compare as well as spot equivalent fractions.  It's also great for students to see how fractions, decimals, and percents relate to each other.   

Who is it for?
I would recommend this app starting in second grade all the way through fifth grade.  It provides a great instructional space for teachers to instruct whole group or with small groups as well as allows a great opportunity for differentiating with the decimal and percent options.   As a visual learner I would of loved to of used this app for adding and subtracting fractions too!  This would be also a great app for student to use with the AirServer for those teachers 

CCSS Connection
Click here to see in detail how this app can help support the Common Core State Standards in math in grades 3-5.   Specifically:
  • Develop understanding of fractions as numbers.
  • Extend understanding of fraction equivalents and ordering.
  • Build fractions from unit fractions.
  • Understand decimal notations for fractions and, compare decimal fractions.
  • Use equivalent fractions as a strategy to add and subtract fractions.



If you'd like a demo of this app or help implementing in your classroom, please let me know!  I'm happy to help!
