Fraction Operations

Description

This math clip art image illustrates the process of dividing five-eighths by 2 using a rectangular model. The model depicts a rectangle divided into eight equal horizontal strips, with five of these strips shaded to represent five-eighths. To demonstrate the division by 2, each horizontal strip is further divided into two equal parts using vertical lines, creating 16 total parts.

In this model, the original five-eighths (5 horizontal strips) are now divided into 10 smaller rectangles. When we divide these 10 parts among 2 (the divisor), we get 5 small parts per group. These 5 small parts out of 16 total parts give us the final answer: 5/16.

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 * 2 = 16).

Teacher's Script: "Look at our rectangular fraction model showing five-eighths. We need to divide this into 2 equal parts. How can we achieve this? We'll divide each eighth into 2 smaller pieces using vertical lines. Count how many of these new, smaller rectangles are shaded. Now, let's divide these shaded parts into 2 groups. How many small parts are in each group? What fraction of the whole does this represent?"
