When counting bigger numbers such as 37 or 58, it is easier to break them up into tens and ones. Remember, one is just one, and ten is a group of 10!

One-to-one correspondence is matching one number to an object whenever you are counting. For example, if you were counting 3 books, you would count: "1 book, 2 books, 3 books." When using one-to-one correspondence, it is best if you touch or point to whatever object you are counting, and say one number for each. This way, you keep track of what you are counting and you stay organized.

Ordinal numbers tell the position of objects, such as who is first, second, third, etc., in something like a race. An example would be Sarah, Kate, and Lily are all standing in a line, Lily is first, Sarah is second, and Kate is third.
