To solve this problem, we need to fill in the missing numbers in the grid. The grid is a "hundred chart," which means it lists numbers from 1 to 100 in order.

Step-by-Step Logic:

1. Understand the Pattern:
* The numbers go in order from left to right: 1, 2, 3, 4...
* When you reach the end of a row (a multiple of 10 like 10, 20, 30), the next number starts on the left of the row below.
* Each row contains 10 numbers. For example, the first row is 1–10, the second is 11–20, and so on.

2. Fill in Row by Row:

* Row 1 (1-10): We have 1, 3, 4, 5, 6, 8, 9.
* Missing after 1 is 2.
* Missing after 6 is 7.
* Missing after 9 is 10.

* Row 2 (11-20): We have 11, 12, 13, 15, 16, 18, 20.
* Missing after 13 is 14.
* Missing after 16 is 17.
* Missing after 18 is 19.

* Row 3 (21-30): We have 21, 23, 24, 27, 29, 30.
* Missing after 21 is 22.
* Missing after 24 are 25 and 26.
* Missing after 27 is 28.

* Row 4 (31-40): We have 32, 34, 36, 38, 40.
* Start of row: 31.
* After 32: 33.
* After 34: 35.
* After 36: 37.
* After 38: 39.

* Row 5 (41-50): We have 41, 43, 45, 47, 49.
* After 41: 42.
* After 43: 44.
* After 45: 46.
* After 47: 48.
* End of row: 50.

* Row 6 (51-60): We have 52, 53, 57, 58, 60.
* Start of row: 51.
* After 53 are 54, 55, 56.
* After 58: 59.

* Row 7 (61-70): We have 61, 63, 65, 66, 68, 69.
* After 61: 62.
* After 63: 64.
* After 66: 67.
* End of row: 70.

* Row 8 (71-80): We have 72, 75, 77, 78, 80.
* Start of row: 71.
* After 72 are 73, 74.
* After 75: 76.
* After 78: 79.

* Row 9 (81-90): We have 81, 82, 85, 88, 89.
* After 82 are 83, 84.
* After 85 are 86, 87.
* End of row: 90.

* Row 10 (91-100): We have 92, 94, 96, 97, 99.
* Start of row: 91.
* After 92: 93.
* After 94: 95.
* After 97: 98.
* End of row: 100.

Final Answer:
Here are the missing numbers to fill in the acorns, listed by row:

* Row 1: 2, 7, 10
* Row 2: 14, 17, 19
* Row 3: 22, 25, 26, 28
* Row 4: 31, 33, 35, 37, 39
* Row 5: 42, 44, 46, 48, 50
* Row 6: 51, 54, 55, 56, 59
* Row 7: 62, 64, 67, 70
* Row 8: 71, 73, 74, 76, 79
* Row 9: 83, 84, 86, 87, 90
