Topic

Fraction Operations

Description

This math clip art image demonstrates the division of three-eighths by 8 using a rectangular model. The model shows a rectangle divided into eight equal horizontal strips, with three of these strips shaded to represent three-eighths. To illustrate the division by 8, each horizontal strip is further divided into eight equal parts using vertical lines, resulting in 64 total parts.

In this model, the original three-eighths (3 horizontal strips) are now divided into 24 smaller rectangles. When we divide these 24 parts among 8 (the divisor), we get 3 small parts per group. These 3 small parts out of 64 total parts represent the final answer: 3/64.

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 * 8 = 64).

Teacher's Script: "Examine our rectangular fraction model showing three-eighths. We need to divide this into 8 equal parts. How can we do this? We'll divide each eighth into 8 smaller pieces using vertical lines. Count how many of these new, smaller rectangles are shaded. Now, let's divide these shaded parts into 8 groups. How many small parts are in each group? What fraction of the whole does this represent?"
