What place value does the diagonal shaded in light green represent?

• Ones

• Tens

• Hundreds

• Thousands

In lattice multiplication, what do the diagonal lines help organize?

• The numbers being multiplied

• The final product

• Place values

• The steps of addition

When multiplying 7 by 4 in the lattice, what is the actual value being calculated?

• 7 multiplied by 4

• 7 multiplied by 40

• 70 multiplied by 4

• 70 multiplied by 40

When multiplying 2 by 4 in the lattice, the result is placed as 0 in the thousands diagonal and 8 in the hundreds diagonal. What is the actual value represented by this result?

• 8

• 80

• 800

• 8000

When using the lattice method to multiply 27 x 48, what does the multiplication of the digit '2' from 27 and the digit '8' from 48 truly represent?

What is the main reason for using diagonal lines in the lattice multiplication method?

• To make the multiplication grid look more interesting

• To separate the numbers being multiplied from each other

• To help organize the numbers by their place value for adding

• To show which numbers need to be carried over to the next step
