Number Bonds: to explore combinations for 5, start with 5 counters in the Whole area of the mat. Ask kiddos to move their counters into the two parts. Avoid saying, "Move 2 counters to one part and 3 to the other." Let them explore and come up with their own combinations. Record the combinations as number bonds on an anchor chart. Keep asking the kiddos to 'show you another way' until all combinations have been recorded.
