DOK 1 Practice

Build fluency with quadratic patterns, forms, zeros, and graph features.

These questions keep the moves direct so students can recognize quadratic structure from tables, equations, and simple graph features.

How to use this set

Look for x², equal second differences, zeros from factors, and vertex information from vertex form.

Set Focus

Foundational quadratic skills

DOK 1 questions reward fast recognition of forms, features, and basic factoring.

Patterns

Recognize constant second differences in tables.

Forms

Connect standard, factored, and vertex form to graph features.

Zeros

Use factors to find solutions and x-intercepts.

Features

Identify vertex, axis of symmetry, intercepts, and opening direction.

Practice Questions

Quadratic Foundations

Check your answer first, then reveal the explanation when you want the model.
