A Closer Look At…Bar Modeling

A pictorial or diagram method of representing quantities and their relationships to solve both

arithmetic and algebraic word problems.

Students use rectangle blocks to represent the known and unknown:•Blocks are easily drawn and divided•Rectangles enable proportional representation and solving for the unit

What can I expect to see…

at home• Same math, different focus-Focus on understanding, as opposed to memorization

• Math talk-More focused vocabulary-Explanation of answers

• Independent practice of concepts-Homework-Games

• Online resources-Student textbook-Background videos/podcasts-Virtual manipulatives
