Count to 100 — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 53, 54, 55
After 53 comes 54, and 54 is followed by 55, so 54 fits in the middle.
2. Next number after 73 is 74
Adding one to 73 gives 74, the next number when counting by ones.
3. 39, 40, 41
After 40 comes 41, since each next number in counting is one bigger.
4. 66, 67, 68
Counting back from 67 by one gives 66, which comes right before 67.
5. Next number after 99 is 100
One more than 99 is 100, which is the final number in counting to 100.
6. 27, 28, 29
After 28 comes 29 because each counting number is one more than the last.
7. Next number after 49 is 50
One more than 49 is 50, which begins the next group of ten.
8. 81, 82, 83
After 81 comes 82, and 82 is followed by 83, so 82 fills the gap.
9. 94, 95, 96
One more than 95 is 96, so 96 comes right after 95 in order.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
41, 42, 43, 44, 45
→ Forties row
Forties row
51, 52, 53, 54, 55
→ Fifties row
Fifties row
61, 62, 63, 64, 65
→ Sixties row
Sixties row
71, 72, 73, 74, 75
→ Seventies row
Seventies row
The tens digit names the row, so 4 means forties, 5 means fifties, and so on.
