For example, this is a one cell lattice that shows the product 8×7: A bigger lattice may represent larger numbers. The number in the cell is the product of two digits, one placed above the cell, the other to its right. Problem in a nice, neat and clean area like thatĪnd we got our answer. Each cell of the lattice is split by the diagonal into two parts used to house a 1- or 2-digit number. Traditional way with carrying and number places, it Let me find a nice suitableĭo for addition. We're done all ofīrains into addition mode. I think you get the ideaĪnd than we have just one, two more diagonals. Row for the 8, and one row for this other 7. And then each one of theseĬharacters got their own row. Just to show that this'll work for any problem. Have a 1 in your 1,000's place just like that. Place and you carry the 1 into your 1,000's place. The 100's place because this isn't just 19, it'sĪctually 190. In the 10's place and now you carry the 1 in 19 up there into This math worksheet was created on and has been viewed 1 times this week and 32 times this month.
