CogAT Quantitative Questions for Grade 6 - Number Series

Posted on July 18, 2025

Can your child crack the pattern before the timer runs out? That’s the challenge behind the Number Series section of the CogAT Grade 6 Quantitative Battery—and with the Gifted Prep App, your child can master it through guided, game-like practice. 

The Number Series section is more than just math. It tests how well your child can identify numerical patterns, apply logical rules, and predict what comes next. This is a core skill measured in the CogAT Quantitative Battery—and it becomes increasingly important in Grade 6, where patterns can involve more complex sequences. 

We’ve included 10 free sample Number Series questions for CogAT Grade 6 below. These questions can help you quickly assess your child’s comfort with recognizing and applying patterns.
