  8. Lattice multiplication (327 x 28) 3 2 7 2 8

  9. Lattice multiplication (327 x 28) 3 2 7 2 8 Now add the diagonals

  10. Lattice multiplication (327 x 28) 3 2 7 2 8 6 Now add the diagonals

  11. Lattice multiplication (327 x 28) 3 2 7 2 8 6 6+5+4 = 15

  12. Lattice multiplication (327 x 28) 3 2 7 1 2 8 5 6

  13. Lattice multiplication (327 x 28) 3 2 7 1 2 8 5 6 1+1+4+1+4=11

  14. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 1 5 6

  15. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 1 5 6 1+6+2=9

  16. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 9 1 5 6

  17. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 0 9 1 5 6

  18. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 0 9 1 5 6 Now read off the digits according to the diagonal place value columns

  19. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 0 9 1 5 6 6 is in the ones column 5 in the tens 1 in the hundreds 9 in the thousands 0 in the ten-thousands

  20. Lattice multiplication (327 x 28) 3 2 7 1 1 2 8 0 9 1 5 6 6 is in the ones column 5 in the tens 1 in the hundreds 9 in the thousands 0 in the ten-thousands So 327 x 28 = 9156

  21. Lattice multiplication (327 x 28) 1 1 0 9 1 5 6 Now calculate 327 x 28 by another method. Can you see how your method is similar to this one?

  22. Lattice multiplication (327 x 28) 327 x 28 56 160 2400 140 400 6000 9156 1 1 0 9 1 5 6 Did you write out all 6 partial products separately? (like this)

  23. Lattice multiplication (327 x 28) 327 x 28 56 160 2400 140 400 6000 9156 327 x 28 2616 6540 9156 1 1 0 9 1 5 6 Did you write out all 6 partial products separately? (like this) Or did you use a condensed version? (like this)

  24. Lattice multiplication (327 x 28) 327 x 28 56 160 2400 140 400 6000 9156 327 x 28 2616 6540 9156 1 1 0 9 1 5 6 Did you write out all 6 partial products separately? (like this) Or did you use a condensed version? (like this) Challenge: see if you can find each of the 6 partial products in the lattice multiplication!
