So, one tally mark looks like this: |
Two tally marks look like this: ||
And so on! When you get to five, you draw a line across the previous four: ||||
🧮 Numerals: The Number Symbols We Know
Numerals are the symbols we use every day to represent numbers. These are the numbers you see in books, on clocks, and everywhere else! They are a standardized system, so everyone knows exactly what each symbol means.
Examples of numerals include: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 0.
