# Rational-Number Content for Intensive Intervention

## Intensive Intervention in Mathematics Course: Module 7 Overview

In Modules 4 and 5, we emphasized important instructional delivery methods and strategies to include when providing instruction within intensive intervention. Modules 6 and 7 focus on important concepts and procedures for whole numbers (Module 6) and rational numbers (Module 7) teachers may find important for being able to explain mathematics to students. In Module 7, we focus on rational number concepts and computation. In this module, educators will learn about:

• Different models to explain fraction and decimal concepts
• How to explain computation with fractions and decimals in a conceptual way
• How effective rational-number instruction looks within intensive intervention

This module is divided into three parts, with an introduction and closing. A 508 compliant version of the full PowerPoint presentation across all parts of the module is available below.

## Part 1: What rational-number core concepts should be emphasized in intensive intervention?

Part 1 explains the concepts of fractions and decimals. Teachers learn to use the length, area, and set models to explain fractions. Teachers also learn how decimals and percentages relate to fractions.

### Worksheets & Activities

Activity 1 - Using the Length Model with a Student

Activity 2 - Using the Area Model with a Student

Activity 3 - Using the Set Model with a Student

Discussion Board – Favorite Fraction Tools

## Part 2: What rational-number procedures should be emphasized in intensive intervention?

Part 2 reviews addition, subtraction, multiplication, and division with fractions and decimals. Teachers learn how to model finding common denominators. We also review how to explain fraction computation conceptually. We conclude with a brief example of using concrete manipulatives to demonstrate computation with decimals.

### Worksheets & Activities

Activity 4 - Modeling Addition and Subtraction of Fractions

Activity 5 - Modeling Multiplication and Division of Fractions

Activity 6 - Using CRA to Teach Decimals

Discussion Board – Application to Ratio and Proportion Problems

## Part 3: What does DBI look like with intensive interventions that focus on conceptual and procedural understanding of rational numbers?

Part 3 provides video and intervention examples of intensive intervention on rational-number content. Teachers review several videos to see how teachers use explicit instruction, multiple representations, and concise language to teach about rational numbers. Teachers also read an excerpt from an evidence-based intervention focused on rational numbers to identify how instructional delivery (Module 4) and strategies (Module 5) work together within intensive intervention.
