Dreambox

Dreambox offers online manipulatives ("teacher tools) for kindergarten through 8th grade.  They are all meant for an interactive whiteboard and are used for number sense, equivalence, addition, subtraction, geometry, algebra and functions.  Each grade level is broken into two sections depending on what the the manipulatives address.  When you click on your topic choice, a description will open about the manipulative and how it's used; you will also have the option to use the tool in Spanish.  Once you open the tool, make sure the volume is turned up for you can hear the directions.  For the fourth grade ordering fractions activity, students are given a number line and asked to place given fractions in the correct order.  When the student makes a mistake, hints are given by showing equivalent fractions.  Once you get three correct, you are moved to a new screen to work with fractions with a different denominator.  This would be a great interactive resource to use for a whole group lesson, but these would really lend themselves well to center activities for students.  They're simple activities, but with the oral directions that are present in these activities it makes them possible for independent work.

Standards:
