Description

This math clip art image demonstrates the division of four-eighths by 5 using a rectangular model. The model shows a rectangle divided into eight equal horizontal strips, with four of these strips shaded to represent four-eighths. To illustrate the division by 5, each horizontal strip is further divided into five equal parts using vertical lines, resulting in 40 total parts.

In this model, the original four-eighths (4 horizontal strips) are now divided into 20 smaller rectangles. When we divide these 20 parts among 5 (the divisor), we get 4 small parts per group. These 4 small parts out of 40 total parts represent the final answer: 4/40, which can be simplified to 1/10.

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 * 5 = 40).

Teacher's Script: "Examine our rectangular fraction model showing four-eighths. We need to divide this into 5 equal parts. How can we do this? We'll divide each eighth into 5 smaller pieces using vertical lines. Count how many of these new, smaller rectangles are shaded. Now, let's divide these shaded parts into 5 groups. How many small parts are in each group? What fraction of the whole does this represent? Can we simplify this fraction?"
