About this resource
Description
Adding two-digit numbers in columns means lining up the tens and ones, adding the ones first, and regrouping when the ones make ten or more. The Adding Two Digit Numbers Activity turns that skill into a travel game, so 2nd and 3rd Grade students practice adding two, three or even four two-digit numbers in a row.
Students pick a Suitcase Card that says how many Number Cards to pack: two, three or four. They take that many luggage-tag Number Cards, write the numbers in a place value grid on their Travel Log, and find the total. All of the numbers are small enough that every sum stays below 100, so students can focus on lining up places and regrouping. A practice page has six more column problems with three and four addends.
What’s Included
- A cover page and a How to Use page
- 6 Suitcase Cards and 24 luggage-tag Number Cards
- A Travel Log recording sheet with tens and ones grids
- A 2nd Grade practice worksheet
- A sample Travel Log and the practice answer key
Why It Helps Kids Learn
First, the tens and ones grid keeps every digit in the right place. Second, drawing different numbers of cards gives practice with two, three and four addends. Third, the game gives students a reason to add again and again, which builds speed and confidence.
Ideas for Teachers and Parents
Use this 2nd grade addition activity in a math center, as a partner game, or for small group review. Have partners compare sums to see who packed the heaviest suitcase. You can also ask students to explain how they regrouped, or to check a partner’s work by adding the numbers in a different order. The Adding Two Digit Numbers Activity is also a quick and easy game to play at home.
