Identifying Strategies for Multi-Digit Addition

**Strategy #1: Counting up**
27 + 4 = **31**
Counting up is useful when one of the numbers that you want to add is small, like 4.

**Using 100 as an Anchor for addition**

**Strategy #2: Using **100** as an Anchor**
The Spanish club is planning a weekend trip. Each student will need to pay $36 for transportation and $98 for food and lodging. What is the total cost per student?

```
36
+ 98
------
```

To use 100 as an anchor,

1. **Break down the addition:**

36 + 98 can be rewritten to find a way to make 100.

2. **Break 36 into 34 + 2:**

34 + **2** + 98

3. **Now add 34 + 98 to make 100:**

34 + **100** = **134**

The total cost per student is **$134**.
