IM 6.2.5 Practice: Defining Equivalent Ratios
Loading the math board and drawing, please wait…
① This example is a practice problem from Illustrative Mathematics Grade 6, Unit 2, Lesson 5, designed to help students understand the definition and identification of equivalent ratios through real-world contexts. ② The core mathematical concept is ratio and equivalent ratios—two ratios are equivalent if they represent the same multiplicative relationship, such as 2:3 and 4:6, obtained by multiplying or dividing both terms by the same non-zero number. ③ Construction notes: Although no specific GeoGebra commands are listed in the summary, such practice typically uses tables, number lines, or double number lines to visualize corresponding values, and may include sliders or dynamic text to demonstrate equivalence. ④ It is suitable for upper elementary (Grade 6) mathematics classrooms as a concept reinforcement exercise, for teacher demonstrations, or for student self-exploration to build intuitive proportional reasoning.

Create a visual for a sixth-grade ratio practice: place a slider on the left to adjust a quantity (like apples), and on the right show the corresponding quantity (like oranges) that always maintains the same multiplicative relationship. In the center, draw two parallel number lines representing these two sets of quantities, mark points with dots, and connect corresponding points to show equivalent ratios. Above, label an example like '2:3 is equivalent to 4:6', and leave blank space below for students to fill in other equivalent ratios. Use simple lines and bright colors for classroom demonstration.
