Embark on an exciting road trip while mastering the art of adding three-digit numbers with the standard algorithm. Buckle up for a fun math adventure!
Imagine you’re on an exciting road trip with your family, and the open road is calling your name! To make the journey even more fun, you decide to belt out your favorite road trip song.
As the tunes fill the car, you start to think: “How many miles will we travel today?”
Dive into the adventure of adding up all those miles and see just how far you can go!
Alright, road tripper! It's time to put on your mathematician hat and use addition to calculate how many miles your family travels.
Stop 1: The Amusement Park
You leave your house and travel 132 miles to a rest stop and then 241 miles to the amusement park.
Add them up!
132 + 241 = ?
To find the total, you can use the standard algorithm. Here’s how.
Line up the numbers by place value. The ones go under the ones, the tens under the tens, and the hundreds under the hundreds.
Start adding from the right! Add the ones column first, then the tens column, and finally the hundreds column.
| hundreds | tens | ones | ||||
| 1 | 3 | 2 | ||||
| 2 | 4 | 1 | ||||
| + | 3 | 7 | 3 |
So 132 + 214 = 373.
You and your family have traveled 373 miles to the amusement park!
Stop Two: Lunch Time
After all that fun, you leave the amusement park and drive 135 miles on Highway A and 158 miles on Highway B to reach a restaurant for some delicious lunch.
Line up the digits by place value again and start with the ones column. This time, you may need to regroup if the numbers add up to more than 10!
| hundreds | tens | ones | ||||
| 1 | 13 | 5 | ← | The 1 from 5 + 8 goes here in the tens place. | ||
| 1 | 5 | 8 | ||||
| + | 2 | 9 | 3 | ← | 5 + 8 = 13, but only ones can go in this column. You have to regroup |
You traveled 293 miles to lunch. Time to dig in and enjoy some yummy food!
At the restaurant, you spot some fun puzzles about the food they serve.
You got this, road tripper!
Fantastic work!
Time to hit the road again!
Stop 3: Hotel Time
After lunch, you drive 284 miles before stopping to stretch your legs, then 231 miles to a rest stop, and finally 242 miles to your hotel for a cozy night’s sleep.
Remember to line up your digits by place value. Start by adding the ones column first!
When you're ready, check your answer by flipping over the card.
Way to go, road-trip whiz!
