Master these essential reading and writing skills aligned with 1st grade standards
Numbers are like students in line - the left position is 'tens place' and the right position is 'ones place'.
Example:
In 34, 3 is in the tens place (3 tens) and 4 is in the ones place (4 ones)
When reading numbers, read the tens digit first, then the ones digit. 34 is read as 'thirty-four', not 'three-four'.
Example:
34 → thirty-four, 90 → ninety (not 'nine-zero')
When writing numbers, write the tens digit first, then the ones digit. For multiples of ten, write '0' in the ones place.
Example:
Twenty-seven → 27 (tens: 2, ones: 7), Fifty → 50 (tens: 5, ones: 0)
A number has three forms: symbol (22), name (twenty-two), and stick representation (2 bundles + 2 sticks).
Example:
22 = twenty-two = 2 tens + 2 ones
