Anti-Number Pairs (Kindergarten 10-14-10)
Posted on October 14th, 2010 by kramer
This week we introduced anti-numbers like anti-tens. The "anti-ten" of 3 is 7; the "anti-ten" of 4 is 6 and so on.
We gave the children several anti-numbers to challenge them to understand friendly numbers and important pairs. For example, they should know their anti-nines and frankly any anti-prime number.
