Cards in this deck (8)
- 1What are the two number systems infants use to make judgments about quantities?Object file system
Analog magnitude system - 2What is subitization?Automatic perception, no counting needed.
Just look at something and know there are 3
Numbers 4 or fewer - 3What are object files?Use one to one correspondence to decide if more/less/same
Each object is a distinct symbol and the number is figured out by evaluating the files - 4What is analog magnitude?Can subitize small numbers because there are great differences between the quantities

Some things are more or less
