Since I can't view or access images directly, I can't see the specific addition problems in your image. However, if you describe the problem or list the addition equations (for example, "523 + 416", etc.), I can help you solve them step by step and explain the process.
Alternatively, if you're asking for a general strategy to solve a "3-Minute Math Addition" worksheet like the one described:
Here's how to approach it:
Goal: Solve as many addition problems as possible in 3 minutes.

Step-by-Step Strategy:
1.
Scan the Problems Quickly
- Look at all the problems first.
- Identify which ones are easier (e.g., small numbers, no carrying) and prioritize them.
2.
Use Mental Math Techniques
-
Break Numbers Down: For example, instead of adding 523 + 416, think:
- 500 + 400 = 900
- 20 + 10 = 30
- 3 + 6 = 9
- Total: 900 + 30 + 9 = 939
-
Add Left to Right: Start with the largest place values first (hundreds, then tens, then ones).
3.
Watch for Carrying
- When adding digits in a column, if the sum is 10 or more, carry over to the next column.
- Example: 7 + 8 = 15 → write down 5, carry 1.
4.
Practice Speed and Accuracy
- The goal is speed, but accuracy matters too. Don’t rush so much that you make mistakes.
5.
Time Management
- Try to spend about 1–2 seconds per problem.
- If stuck on one, skip and come back later.

Example Problem Solved:
Let’s take one from the worksheet:
523 + 416
- Add hundreds: 500 + 400 = 900
- Add tens: 20 + 10 = 30
- Add ones: 3 + 6 = 9
- Total: 900 + 30 + 9 =
939
✔ Answer:
939

If you can type out the problems from the image (or copy-paste them), I’ll solve each one and show you the steps!
Parent Tip: Review the logic above to help your child master the concept of math drills 3rd grade.
