Description

This math clip art image demonstrates the division of seven-eighths by 3 using a rectangular model. The model shows a rectangle divided into eight equal horizontal strips, with seven of these strips shaded to represent seven-eighths. To illustrate the division by 3, each horizontal strip is further divided into three equal parts using vertical lines, resulting in 24 total parts.

In this model, the original seven-eighths (7 horizontal strips) are now divided into 21 smaller rectangles. When we divide these 21 parts among 3 (the divisor), we get 7 small parts per group. These 7 small parts out of 24 total parts represent the final answer: 7/24.

This visual representation helps students understand that dividing a fraction by a whole number results in a smaller fraction. It also demonstrates how the denominator of the original fraction is multiplied by the divisor to get the new denominator (8 * 3 = 24).

Teacher's Script: "Examine our rectangular fraction model showing seven-eighths. We need to divide this into 3 equal parts. How can we do this? We'll divide each eighth into 3 smaller pieces using vertical lines. Count how many of these new, smaller rectangles are shaded. Now, let's divide these shaded parts into 3 groups. How many small parts are in each group? What fraction of the whole does this represent?"
