To create a tally chart for the number of students in the third, fourth, and fifth-grade classes, follow these steps:

1. Start by drawing a table with two columns: one for the numbers and one for the tally marks.

Number | Tally
---------------------------

2. Begin by listing all the numbers in ascending order:

Number | Tally
---------------------------
25 |
26 |
26 |
27 |
27 |
27 |
28 |

3. Now, add tally marks next to each number. A tally mark is a diagonal line (/) used to represent each number:

Number | Tally
---------------------------
25 | /
26 | //
26 | //
27 | ///
27 | ///
27 | ///
28 | /////

4. Once you finish adding the tally marks, count them in groups of five. Grouping the tally marks helps with the readability and makes it easier to determine the total count:

Number | Tally
---------------------------
25 | /
26 | //
26 | //
27 | ///
27 | ///
27 | ///
28 | /////

5. Finally, count the tally marks and write the total count next to the number of students in each grade:

Number | Tally
---------------------------
25 | / (1)
26 | // (2)
26 | // (2)
27 | /// (3)
27 | /// (3)
27 | /// (3)
28 | ///// (4)

In this example, there is 1 student in the third-grade class (25), 2 students in the fourth-grade class (26), and 3 students in the fifth-grade class (27).
