This was designed to use with Kindergarten. However, they can be used with Pre-K or at the beginning of first grade. There are two different flashcards on each page. According to NYS, students in Kindergarten should be able to name and know the value of the quarter, nickel, dime, and penny. Flashcards contain images of the front and back of each coin. Students also need to know how to count pennies, so multiple flashcards are included where students can count up pennies. This does not fall under common core standards, however, until grade 2: 2.MD.c8. The TPT site will not allow me to assign this standard to a Kindergarten product.
