3 × 4 · 3 rows of 4 objects show the fact 3 × 4.
9 · 3 rows of 3 is 3 + 3 + 3 = 9.
20 · 4 rows of 5 is 5 + 5 + 5 + 5 = 20.
10 · 2 rows of 5 make 10. Count by 5s: 5, 10.
4 + 4 + 4 = 12 · 3 rows of 4 means add 4 three times.
15 · 5 rows of 3 is 15.
5 · 10 split into rows of 2 gives 5 rows.
2 rows of 6 objects · An array for 2 × 6 has 2 rows with 6 objects in each row.
He counted only 4 objects in each row · 3 rows of 5 make 15. Ravi counted only 4 in each row, and 3 rows of 4 make 12.
3 · 15 split into 5s gives 3 rows.
