This easy worksheet pairs handwriting practice with friendly two-digit problems so first graders build vocabulary and number sense together. Part A traces ones, tens, place, value, digit, and number along dotted lines. Part B asks students to fill in blanks for sentences like 'The number 61 has ___ tens', 'The number 45 has ___ ones', and 'The number 90 has ___ ones', which is the trickiest because the answer is 0. Part C finishes with true-or-false statements including '2 tens and 6 ones make 26' and 'The number 53 has 3 tens.' Working with 90 early helps students notice that a zero in the ones place still counts as a real digit.
