Count to 100 — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. 47, 48, 49
After 47 comes 48, and 48 is followed by 49, so 48 fits in the gap.
2. Next number after 89 is 90
Adding one to 89 gives 90, which begins a new group of ten in counting.
3. 59, 60, 61
After 60 comes 61, since each next counting number is one more than the last.
4. 77, 78, 79
Counting back from 78 by one gives 77, which sits right before 78 in order.
5. 98, 99, 100
One more than 99 is 100, the final number when counting to one hundred.
6. Next number after 35 is 36
Counting forward from 35 by one gives 36, the next number in the order.
7. 69, 70, 71
After 69 comes 70, the next tens number, which sits before 71 in order.
8. Next number after 19 is 20
Counting one more than 19 gives 20, starting the next group of ten.
9. 84, 85, 86
One more than 85 is 86, so 86 comes right after 85 in counting order.
