Practice number sense skills using beads on the virtual number rack (similar to an abacus). Movable beads encourage you to think in groups of fives and tens while practicing addition, subtraction, multiplication, and division strategies. Add or subtract rows of beads using links provided. Display up to 100 beads at one time. Use the shade key to hide beads or drag the corner of the bead to move or change its size. Use the start over button to clear the rack and start with a new set of beads. Be sure to visit the information portion of the site for free resources, including a 10 page activity book for use with the virtual number rack. Click on the lowercase "i" at the bottom right for complete directions.

In the Classroom
View the virtual number board together as a class (or a center) on your interactive whiteboard or projector to practice counting and basic operational skills. Use this with younger students learning to count to 10 or 100. Create a link on classroom computers for students to explore and practice on their own. Share a link to the site on your class website or blog for students to practice at home. When finished, have students draw the problems they created and include the appropriate number sentence for each drawing.You must be registered and logged in to add items to your favorites.
