My first thought when I saw the Hide Zero Cards template in my EngageNY/ Eureka math curriculum was, "you've got to be kidding me!" The cards that come with the program are teeny tiny, and even with the dexterity of a 2nd grader I imagined they'd get dropped frequently and lost easily.
These cards are a chunkier version of the hide zero cards from EngageNY/Eureka. They are intended to be layered on top of each other and then pulled apart to help students understand place value. They're hardy enough to use whole group or individually. I've added a directional arrow to remind younger students which way we read numbers. The cards can be used to build numbers up to 9999.
Print them on Astrobrights colored paper and laminate them for durability; you won't have to worry about your students losing their hide zero cards ever again.
