Rounding with Scaffolded Handout

This post shows an approach to teach rounding to the nearest 10 and is presented on a handout. Multiple strategies are used. This includes scaffolding, chunking with supports incrementally faded, and a visual.

Overview

A visual of the hand releasing the balloon draws upon prior knowledge and provides a mnemonic for when to round up. The scaffolding provides support to focus on fewer parts of the problem. The supports are faded to incrementally increase task demand placed on the student.

Handout

The first page has maximum scaffolding with the student focusing only on which tens to round to. In turn, an a different element is the focus (e.g., writing the 0s then rounding) and then the scaffolding is increasingly faded.

Color Coding and Different Representation for Rounding

There are two strategies used in this example for rounding.

The number line is a different representation for a rounding situation. In CRA this is the representational or pictorial level. Typically students are taught to round by looking only at the numbers which is purely symbolic.

The color coding helps the students discriminate between the number being rounded and the choices for rounding. As I’ve written previously, color coding helps a student discern different parts of a concept.
