Adding rational numbers with fractions is one of the most challenging skills for middle school students. This intervention breaks the process into manageable steps and explicitly addresses common student misconceptions with unlike denominators and negative values.

This resource was designed after analyzing real student errors and uses a thin-slice scaffolding approach to gradually increase complexity. Each intervention day includes structured I Do, We Do, You Do practice to support struggling learners without overwhelming them.

What’s included:

• 4-day intervention sequence
• Day 1: Finding the LCM of unlike denominators and writing equivalent fractions
• Day 2: Adding fractions with like denominators (including negatives)
• Day 3: Adding fractions with unlike denominators (including negatives)
• Visual supports and number line helpers
• Progress monitoring assessment
• Answer key

Who it’s for:

Ideal for Tier 2 and Tier 3 intervention, small groups, special education, or reteaching after initial instruction.
