Cardinality is the idea that the last number counted is the total. Ask a child to count 5 objects. He or she may be able to count them correctly 1,2,3,4,5. Now ask the child, “how many are there?” If the child can tell you that there are 5 objects, he or she understands the concept of cardinality. If the child goes back and counts the objects again, “1,2,3,4,5”, he or she does not yet have an understanding of cardinality. Here are a few ideas for using ten frames for counting and cardinality practice.
- Ask kids to count as they place objects in a frame. When they are done, ask “how many are there?”
- Ask them to “show you” 5, 7, 9……..
- Roll a die and fill the frame to represent that number.
- Use 1-10 number cards. Draw a card, say the number, and represent the number on the ten frame.
