I can cut a rectangle into rows and columns of equal squares.
Look: 2 rows and 3 columns
- Draw lines with a ruler to make 2 rows and 3 columns.
- Count by rows: 3 + 3 = 6.
- Count by columns: 2 + 2 + 2 = 6.
Draw each rectangle. Partition it. Write an addition sentence for rows and for columns.
- 3 rows, 5 columnsAnswer: 5 + 5 + 5 = 15; 3 + 3 + 3 + 3 + 3 = 15
- 2 rows, 6 columnsAnswer: 6 + 6 = 12; 2 + 2 + 2 + 2 + 2 + 2 = 12
- 4 rows, 4 columnsAnswer: 4 + 4 + 4 + 4 = 16
Solve.
