The Rekenrek tool helps to build a deeper understanding of number concepts and relationships.
Make visual models that help explore mathematical thinking related to:
•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
•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.

Very practical tool
Students love this. It offers all the benefits of a standard Rekenrek with many bonuses. Work with numbers > 20, annotate thinking, change colours, adjust size...very intuitive for students who have so many ways to explore number. Highly recommend it.
