Math Number Pyramid Puzzle Game + Worksheets - Free Printable

Let's solve each of these addition pyramid puzzles step by step.

In an addition pyramid:
- Each number in a higher row is the sum of the two numbers directly below it.
- We start from the bottom and work our way up, adding adjacent numbers to fill in the blanks.

We'll go through each pyramid one at a time.

🔷 Pyramid 1

```
[ ]
[ ] [ ]
[20] [ ] [ ]
[10][10][5][20]
```

#### Step 1: Fill the second row from bottom
- The third row (from bottom) has three boxes. The first one is given as 20, so we need to find the other two.

But wait — actually, the structure is:
- Bottom row: 10, 10, 5, 20 → four numbers
- Next row: 3 numbers (20, ?, ?)
- Then: 2 numbers
- Top: 1 number

So:

Row 4 (bottom): 10, 10, 5, 20
Row 3: 20, ?, ?
Row 2: ?, ?
Row 1 (top): ?

Let’s compute upward.

#### Row 3 (just above bottom):
- First box: 10 + 10 = 20 ✔ (already given)
- Second box: 10 + 5 = 15
- Third box: 5 + 20 = 25

So Row 3: 20, 15, 25

#### Row 2:
- First box: 20 + 15 = 35
- Second box: 15 + 25 = 40

#### Row 1 (top):
- 35 + 40 = 75

✔ So top number = 75

🔷 Pyramid 2

```
[ ]
[ ] [ ]
[26] [ ] [ ]
[14][12][7][25]
```

Bottom row: 14, 12, 7, 25

#### Row 3:
- 14 + 12 = 26 ✔ (given)
- 12 + 7 = 19
- 7 + 25 = 32

Row 3: 26, 19, 32

#### Row 2:
- 26 + 19 = 45
- 19 + 32 = 51

#### Row 1:
- 45 + 51 = 96

✔ Top = 96

🔷 Pyramid 3

```
[ ]
[ ] [ ]
[21] [ ] [ ]
[9][12][11][6]
```

Bottom: 9, 12, 11, 6

#### Row 3:
- 9 + 12 = 21 ✔ (given)
- 12 + 11 = 23
- 11 + 6 = 17

Row 3: 21, 23, 17

#### Row 2:
- 21 + 23 = 44
- 23 + 17 = 40

#### Row 1:
- 44 + 40 = 84

✔ Top = 84

🔷 Pyramid 4

```
[ ]
[ ] [ ]
[18] [ ] [ ]
[10][8][11][4]
```

Bottom: 10, 8, 11, 4

#### Row 3:
- 10 + 8 = 18 ✔ (given)
- 8 + 11 = 19
- 11 + 4 = 15

Row 3: 18, 19, 15

#### Row 2:
- 18 + 19 = 37
- 19 + 15 = 34

#### Row 1:
- 37 + 34 = 71

✔ Top = 71

---

🔷 Pyramid 5

```
[ ]
[ ] [ ]
[18] [ ] [ ]
[7][11][8][22]
```

Bottom: 7, 11, 8, 22

#### Row 3:
- 7 + 11 = 18 ✔ (given)
- 11 + 8 = 19
- 8 + 22 = 30

Row 3: 18, 19, 30

#### Row 2:
- 18 + 19 = 37
- 19 + 30 = 49

#### Row 1:
- 37 + 49 = 86

✔ Top = 86

---

🔷 Pyramid 6

```
[ ]
[ ] [ ]
[23] [ ] [ ]
[13][10][5][17]
```

Bottom: 13, 10, 5, 17

#### Row 3:
- 13 + 10 = 23 ✔ (given)
- 10 + 5 = 15
- 5 + 17 = 22

Row 3: 23, 15, 22

#### Row 2:
- 23 + 15 = 38
- 15 + 22 = 37

#### Row 1:
- 38 + 37 = 75

✔ Top = 75

📝 Summary:

You can now fill in all the blank boxes using the same logic. For example:

Pyramid 1:
```
[75]
[35][40]
[20][15][25]
[10][10][5][20]
```

And so on for others.
