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.
9.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Multiply 5 * 5 and place the answer in the grid where the lines meet. 5 2
10.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Multiply 3 * 5 and place the answer in the grid where the lines meet. 5 2 5 1
11.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 2 5 1 0
12.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 2 5 1 0 0 +1
13.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 2 5 1 0 0 +1 9
14.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 2 5 1 0 0 +1 9 8
15.
356 * 25 3 5 6 2 5 1 2 0 1 6 0 0 3 Now add the diagonals and place the answer below the grid. Be sure to carry to the next diagonal if you have a 2 digit answer. 5 2 5 1 0 0 +1 9 8

356 * 25 = 8,900 That is Soooo Cool!!! Thanks!
