The document is a math worksheet about swapping amounts for tens and hundreds. It contains multiple math problems where students are asked to swap numbers in the tens or hundreds place and solve the equations. For example, it may ask 30 + 10 = ? and the student would swap the tens place to get 40. Or it may ask 400 + 200 = ? and the student would swap the hundreds place to get 600. The worksheet provides practice swapping numbers in the tens and hundreds places to solve equations.

2. Swap for 10s
3 + 1 = 4
so
30 + 10 =

3. Swap for 10s
5 + 2 = 7
so
50 + 20 =

4. Swap for 10s
4 + 3 = 7
so
40 + 30 =

5. Swap for 10s
8 + 1 = 9
so
80 + 10 =

6. Swap for 10s
7 + 2 = 9
so
70 + 20 =

7. Swap for 10s
5 + 5 = 100
so
50 + 50 =

8. Swap for 10s
9 - 2 = 7
so
90 - 20 =

9. Swap for 10s
5 - 3 = 2
so
50 - 30 =

10. Swap for 10s
8 - 2 = 6
so
80 - 20 =

11. Swap for 100s
4 + 2 = 6
so
400 + 200 =

12. Swap for 100s
6 + 3 = 9
so
600 + 300 =

13. Swap for 100s
6 + 1 = 7
so
600 + 100 =

14. Swap for 100s
8 + 1 = 9
so
800 + 100 =

15. Swap for 100s
9 - 1 = 8
so
900 - 100 =

16. Swap for 100s
5 - 1 = 4
so
500 - 100 =

17. Swap for 100s
6 - 2 = 4
so
600 - 200 =

18. Swap for 1000s
2 + 2 = 4
so
2000 + 2000 =

19. Swap for 1000s
5 + 2 = 7
so
5000 + 2000 =

20. Swap for 1000s
7 + 2 = 9
so
7000 + 2000 =

21. Swap for 1000s
9 - 3 = 6
so
9000 - 3000 =
