Question

draw a model to represent the following problem. 2×7

Explanation:

Step1: Interpret the multiplication

The expression \(2 \times 7\) can be interpreted as 2 groups of 7 or 7 groups of 2. Let's use the "2 groups of 7" interpretation for the model.

Step2: Draw the first group

Draw 7 objects (e.g., circles) in a row to represent the first group of 7.
○ ○ ○ ○ ○ ○ ○

Step3: Draw the second group

Draw another row of 7 circles to represent the second group of 7.
○ ○ ○ ○ ○ ○ ○
(Alternatively, if we use the "7 groups of 2" interpretation, we can draw 7 rows with 2 circles in each row:

Answer:

A model for \(2 \times 7\) can be two rows (or groups) of 7 objects (e.g., circles) as shown:

Row 1: ○ ○ ○ ○ ○ ○ ○
Row 2: ○ ○ ○ ○ ○ ○ ○

(Or seven columns of 2 objects each:

Column 1: ○
○
Column 2: ○
