•representing numbers in different ways, composing and decomposing numbers
•subitizing (instantly seeing “how many”)
•counting principles
•understanding addition and subtraction
•developing multiplicative thinking
•visualizing division facts

Features:

•Adjust the number of rows.
•Choose a background colour and bead colours.
•Drag the rods to compare values.

This tool from http://mathies.ca and http://mathclips.ca is explained. Rekenreks are arithmetic racks. They commonly have two rods of beads, however, this digital version allows the user to adjust the number of rods. Each rod has ten beads, five of one colour followed by five of another colour. Use the Rekenrek to build understanding of whole numbers, number relationships, and strategic reasoning for counting, addition, subtraction and multiplication. Relate numbers to the anchors of 5 and 10.
