I use this activity to build understanding with equivalent fractions.Students model equivalent fractions with fraction bar models and number lines.  In both types of models students need to focus on partitioning or ceating equal parts.  They also need to make sure their models are properly labeled.Naming the multiplier or divisor allows students to practice with simplifying or unsimplifying fractions.

This webpage allows students to independently read and interpret word problems related to fraction knowledge, develop an understanding of tape diagram models and solve problems with this type of visual display. It reinforces precise vocabulary, labeling parts, and preparing a diagram proportionally. It provides a calculator for students to use who need scaffolding/modification.
