🌟 Understanding the Maya Number System (0–19)

The Maya used a base-20 system, but for numbers 0–19, they used a vertical place value system with only three symbols:

- Shell = `0`
- Dot = `1`
- Bar = `5`

To read a number:
- Add up the values of all the dots and bars in the symbol.
- Dots are worth 1 each, bars are worth 5 each.
- There is no concept of place value within 0–19 — it’s just additive!

> Example from the worksheet:
> Two dots (1+1=2) + three bars (5+5+5=15) → Total = 2 + 15 = 17

✔ Let’s Solve Each Box

We’ll go row by row, left to right.

---

#### 🔹 Row 1

1. Top-left box:
- One dot → `1`
→ Answer: 1

2. Top-middle box:
- Four dots → `1+1+1+1 = 4`
→ Answer: 4

3. Top-right box:
- Two dots + two bars → `1+1 + 5+5 = 12`
→ Answer: 12

---

#### 🔹 Row 2

4. Second row, left:
- Three dots → `3`
→ Answer: 3

5. Second row, middle:
- Two dots → `2`
→ Answer: 2

6. Second row, right:
- One dot + one bar → `1 + 5 = 6`
→ Answer: 6

---

#### 🔹 Row 3

7. Third row, left:
- Three dots + two bars → `1+1+1 + 5+5 = 13`
→ Answer: 13

8. Third row, middle:
- Two dots → `2`
→ Answer: 2

9. Third row, right:
- Three dots + three bars → `1+1+1 + 5+5+5 = 18`
→ Answer: 18

---

#### 🔹 Row 4

10. Bottom-left box:
- One dot + two bars → `1 + 5+5 = 11`
→ Answer: 11

11. Bottom-middle box:
- Four dots + three bars → `1+1+1+1 + 5+5+5 = 4 + 15 = 19`
→ Answer: 19

12. Bottom-right box:
- Five dots → `5`
→ Answer: 5

*(Note: Maya usually write 5 as one bar, not five dots — but sometimes they do use dots for small numbers. So 5 dots = 5.)*

📝 Final Answers (Fill in the blanks):

Row 1:
→ 1, 4, 12

Row 2:
→ 3, 2, 6

Row 3:
→ 13, 2, 18

Row 4:
→ 11, 19, 5

💡 Teaching Tip:

You can reinforce this by having students draw the symbols for numbers like 7 (one bar + two dots), or 10 (two bars), or 16 (three bars + one dot).

---

✔ All done! You now understand how to read Maya numbers 0–19 using dots and bars.

Let me know if you’d like to extend this to larger numbers (like 20+) using the full base-20 system!
