Extending the Make Ten Addition Strategy Beyond the Facts (Math Stepping Stones 6.3) Example #1 I will start on 29. I know that if I add 1, I will land on 30. 30 is a friendly number (nearest ten). Then I have 3 more to add. So, 30 +3 =33. The jumps on the number line show I added the numbers. This is called bridging. Another way to think about it: 29 +4 is the same as 29+ 1 + 3. 29 +1 + 3 (You want to get to the nearest ten.) 30 + 3 = 33 Example #2 Looking at this equation, I want to start with the greater number. I will start on 58. I know that if I add 2, I will land on 60. 60 is a friendly number (nearest ten). Then I have 4 more to add. So, 60 +4 =64. The jumps on the number line show I added the numbers. This is called bridging. Another way to think about it: 58 +6 is the same as 58+ 2 + 4. 58 +2 + 4 (You want to get to the nearest ten.) 60 + 4 = 64
