Every two-digit number is some tens and some ones: 47 is 4 tens and 7 ones. Knowing that is the base of everything first graders do next, from comparing numbers to adding tens. On this worksheet each line breaks a number into tens and ones and leaves one gap, such as 47 = ____ tens and 7 ones or 47 = 4 tens and ____ ones, and your child writes the missing number.
The gap is sometimes the tens and sometimes the ones. Support sheets use numbers from 20 to 59, standard sheets go up to 99, and challenge sheets include numbers with no ones, such as 60 = 6 tens and 0 ones. Look at the two digits: the left one counts the tens, the right one counts the ones.
