30-Item Test Blueprint — Grade 6 Ratios & Proportional Relationships (6.RP.A)
Executive Summary
This 30-item blueprint assesses Grade 6 Ratios and Proportional Relationships (6.RP.A) across seven sub-standards. Items span DOK levels 1–3 (6 DOK-1, 12 DOK-2, 3 DOK-3, with 4 higher-complexity DOK-3/4 items treated as DOK-3 for reporting, totaling 19 DOK-2+ items). Claim distribution approximates SBAC targets: ~57% Claim 1 (Concepts & Procedures), ~27% Claims 2 & 4 (Problem Solving & Reasoning), and ~16% Claim 3 (Communicating Reasoning). Five Learnosity item types are used to ensure variety and accessibility. Sub-standard item counts strictly follow the prescribed item_split. The assessment covers ratio concept and language, unit rate, equivalent ratio tables, percent problems, and unit conversion.
Standards & Cognitive Rigor Summary
| Standard | Description | Items | DOK Levels |
|---|---|---|---|
| 6.RP.A.1 | Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. | 4 | DOK 1, DOK 2 |
| 6.RP.A.2 | Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. | 4 | DOK 1, DOK 2 |
| 6.RP.A.3 | Use ratio and rate reasoning to solve real-world and mathematical problems by reasoning about equivalent ratios and rates (umbrella standard). | 3 | DOK 2, DOK 3 |
| 6.RP.A.3.a | Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. | 5 | DOK 1, DOK 2, DOK 3 |
| 6.RP.A.3.b | Solve unit rate problems including those involving unit pricing and constant speed. | 5 | DOK 1, DOK 2, DOK 3 |
| 6.RP.A.3.c | Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, given a part and the percent. | 5 | DOK 2, DOK 3 |
| 6.RP.A.3.d | Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities. | 4 | DOK 1, DOK 2, DOK 3 |
