use modulo with a conditional.

## Name

## Directions

Use this activity document to guide your work in the [flipping bird tutorial](/lessons/flipping-bird/tutorial).

Answer the questions while completing the tutorial. Pay attention to the dialogues!

## 1. What does "modulo" mean in math?

## 2. Consider the following directions

If the rectangle below represents the BBC micro:bit, shade in the LEDs that show the value being stored into  the **global variable**, `count`.

```
count = 1
```

## 3. Consider the following code

If the rectangle below represents the BBC micro:bit, shade in the LEDs that show the value being stored into  the **global variable**, `count`. Explain why that particular area is shaded.

```
count = 1
count_ = count_ + 2
```

## 4. Consider the following directions

Modulo (Mod) tells us what the remainder of a division is. For example, `15 mod 4 is 3` since 15 divided by 4 has a remainder of 3.

```
count = 12
count = math.mod(count, 5)
```

If the rectangle below represents the BBC micro:bit, shade in the LEDs that show the value being stored into  the **global variable**, `count`. Explain why that particular area is shaded.
