This challenging worksheet stretches first graders into expanded form and the value of individual digits. Part A is multiple choice with four problems: picking which number has 6 tens and 2 ones (62), choosing the expanded form of 85 (80 + 5), naming the value of the 4 in 47 (40), and matching 30 + 9 to 39. Part B's five fill-in-the-blanks include '90 + 6 = ___', 'If you add 1 more ten to 34, you get ___', 'The digit in the ones place of 71 is ___', and the capstone 'The largest two-digit number is ___.' Asking for the value of a digit, not just the digit itself, is what makes place value finally click.
