Test questions for 2-digit by 2-digit grid method multiplication

📚 Quick Study Guide

• 🔢 The grid method, also known as box method, breaks down multiplication into smaller, more manageable parts.
• ➗ Decompose each 2-digit number into its tens and ones components (e.g., 23 becomes 20 + 3).
• ✏️ Create a grid with rows and columns corresponding to the decomposed parts of the numbers. For example, for 23 x 34, the grid would be 2x2.
• ➕ Multiply each part and fill in the grid.
• ➕ Finally, add up all the values inside the grid to get the final answer.
• 💡 Example: To multiply 23 x 34:
  • 20 x 30 = 600
  • 20 x 4 = 80
  • 3 x 30 = 90
  • 3 x 4 = 12
  • 600 + 80 + 90 + 12 = 782
