One to one correspondence is the ability to match a each member of one set to each member of a second set. This could mean while setting the table, setting one plate, one fork, and one spoon for each member of the family. It could mean separating specific amounts of crackers for snacks, or giving one ball to each friend. Click here for another post about one to one correspondence.
One to one correspondence is a foundational math skills. A popular activity is called egg carton counting. Supplies include an empty egg carton, some numbered cards (I used Uno), and some sort of counters.
Invite your child to draw a card and identify it’s name. Then have your child count the appropriate number of counters into the egg carton, one counter in each space.
Take care to make sure that only one counter is in each egg compartment. Hence one to one correspondence. Have your child count the counters a second time once they are all in the carton. This is just for additional practice.
