  • 3. HELP!!! I can help!! Let me show you how to do Lattice Multiplication.
  • 4. 356 * 25 3 5 6 2 5 Make a grid the exact size of your problem. A 2 digit number times a 3 digit number gets a 2 x 3 grid. Draw a diagonal line in each box.
  • 5. 356 * 25 3 5 6 2 5 1 2 Multiply 6 * 2 and place the answer in the grid where the lines meet.
  • 6. 356 * 25 3 5 6 2 5 1 2 0 1 Multiply 5 * 2 and place the answer in the grid where the lines meet.
  • 7. 356 * 25 3 5 6 2 5 1 2 0 1 6 0 Multiply 3 * 2 and place the answer in the grid where the lines meet. Use a zero as a place holder.
  • 8. 356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Multiply 6 * 5 and place the answer in the grid where the lines meet.
