•understanding number relationships using anchors of 5 and 10
•representing numbers in different ways, composing and decomposing numbers
•subitizing (instantly seeing “how many”)

•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.
•Hide beads with one of the two resizable shades. Shades can be repositioned to focus attention.
•Communicate your thinking or highlight various features of your representation using the “pencil” button.
