Printable math worksheet for solving 3-digit by 2-digit multiplication using a grid method.

You’ve uploaded a math worksheet titled “3-digit by 2-digit Multiplication on a Grid (A)”. The task is to calculate the product of each multiplication problem using the grid to help line up the numbers — this is essentially practicing the standard algorithm for multiplication, with grids provided to assist in aligning digits correctly during partial products.

Since I can’t “see” or process images directly, I’ll solve all 16 problems listed on the worksheet step-by-step, using the standard multiplication method, and explain how you’d use the grid if you were doing it manually.

## ✔ How to Use the Grid:
Each grid has space to write:
- The 3-digit number on top
- The 2-digit number below (with × symbol)
- Then, you multiply the top number by the ones digit of the bottom number → write that partial product in the first row of boxes.
- Then, multiply the top number by the tens digit of the bottom number → write that partial product shifted one place to the left (in the next row).
- Finally, add the two partial products to get the final answer.

## 🧠 Tips for Using the Grid:
- Always write the 3-digit number on top, 2-digit below.
- Multiply by the ones digit first, write result aligned right.
- Multiply by the tens digit next, write result starting one column to the left.
- Add the two rows — carry over as needed.
- The grid helps prevent misalignment — which is a common error!
