Rekenrek translates loosely to calculation rack or arithmetic rack, and it was designed by a Dutch mathematician. The rekenrek is a great visual model for developing a strong sense of 5 and 10, and it supports a strategy-based approach for learning calculations.
This unit includes:
• Instructions with a materials list and photos for making a class set of DIY rekenreks
• 65 flashcards with instructions for using them with Number Talks
• A Bump game for making 20 with a game board and 32 cards
• A Capture 4 game for making 10 with a game board and 24 cards
