These cards are a simple replication of the Math Common Core Hide Zero Cards. They can be used when counting the say ten way or just to identify how many hundreds, tens, and ones are in a given number.
This is a Frayer Model for number building. A number (in standard form) is written in the middle circle. Students then write the number in expanded and word forms, then model it and compose a related word problem.
