Origami Accordion Number Expanders is what 34J decded to call them, to everyone else they are simply number expanders. Some worked in hundreds, others thousands while a few brave souls ventured into the millions. Everyone demonstrated a clearer understanding after playing with these unique tools. Here Suelaman demonstrates his new hand held expander and Kiki's work below deserved a real 'Henry Woo Hoo!' We will be continuing to use the expanders as we play with renaming numbers and gain further confidence in our place value understandings.
