Strategy
Break big arrays into friendly parts like 5s & 2s or doubles:
7 × 4 = (5 × 4) + (2 × 4) = 20 + 8 = 28
PART 1
Inspect the Cut & Solve the Facts
Fill in the factors for each part, then calculate the total.
1 Array: 6 rows of 7 6 × 7
Left:
× =
Right:
× =
6 × 7 =
2 Array: 4 rows of 8 4 × 8
Left:
× =
Right:
× =
4 × 8 =
3 Array: 3 rows of 9 3 × 9
Left:
× =
Right:
× =
3 × 9 =
4 Array: 8 rows of 6 (Split rows) 8 × 6
Top:
× =
Bottom:
× =
8 × 6 =
PART 2
Draw the Split Line & Solve
Draw a dashed line to break each big array, then write the facts.
5 Break up: 5 rows of 9 5 × 9
5x9 = ( x ) + ( x )
Total:
6 Break up: 7 rows of 6 7 × 6
7 × 6 = ( x ) + ( x )
Total:
7 Break up: 8 rows of 4 8 × 4
8 × 4 = ( x ) + ( x )
Total:
8 Break up: 6 rows of 8 6 × 8
6x8 = ( x ) + ( x )
