Adjusted 30-Item Test Blueprint — Grade 6 Ratios & Proportional Relationships
Executive Summary
This 30-item assessment blueprint targets the full Grade 6 Ratios & Proportional Relationships cluster (6.RP.A). Items are distributed across all seven sub-standards per the supplied item split, with a DOK profile of 6/12/6/6 across DOK levels 1–4 to balance procedural fluency with higher-order modeling and reasoning. Claim distribution follows the SBAC target proportions (~57% Claim 1, ~27% Claims 2 & 4 combined, ~16% Claim 3). All five Learnosity interaction types (MCQ, Multiple Response, Cloze Text, Match List, Drag and Drop) are represented, with lower-DOK items restricted to MCQ/Cloze and higher-DOK items leveraging Match List and Drag and Drop for modeling and multi-step reasoning. Stimuli emphasize tables of equivalent ratios, double number lines, tape diagrams, coordinate plots, and real-world contexts (pricing, speed, percent, unit conversion).
Standards & Cognitive Rigor Summary
| Standard | Description | Items | DOK Levels |
|---|---|---|---|

| 6.RP.A.2 | Understand the concept of a unit rate a/b associated with a ratio a:b (b≠0); use rate language. | 4 | DOK 1–2 |
| 6.RP.A.3 | Use ratio and rate reasoning to solve real-world and mathematical problems (tables, tape diagrams, double number lines, equations). | 3 | DOK 2–4 |
| 6.RP.A.3.a | Make tables of equivalent ratios, find missing values, plot pairs on the coordinate plane, and compare ratios. | 5 | DOK 1–4 |
| 6.RP.A.3.b | Solve unit rate problems including unit pricing and constant speed. | 5 | DOK 1–4 |
| 6.RP.A.3.c | Find a percent of a quantity as a rate per 100; solve problems finding the whole given a part and the percent. | 5 | DOK 2–4 |
| 6.RP.A.3.d | Use ratio reasoning to convert measurement units; manipulate and transform units when multiplying/dividing. | 4 | DOK 2–4 |
