Addition within 10

Adding means putting two groups together and finding how many there are altogether. The quickest way for small numbers is to start at the bigger number and count on. For 6 + 3, hold 6 in your head and count on three more: 7, 8, 9. Because order doesn't change the total, 3 + 6 gives the same answer, so always start from the bigger number to do less counting.
