Calm familiarization, not high-stakes drilling.
A few minutes of practice helps a child feel calm and familiar with reasoning formats on test day. This is about gentle exposure, not anxiety.
The right kinds of practice.
The Practice Lab builds figural, quantitative, and spatial reasoning — the core skills measured by cognitive-ability tests like the NGAT and CogAT.
Encouraging, not punitive.
Puzzles are short and self-contained. Get one wrong and the app offers a calm explanation — not a red X and a penalty.
Three simple steps.
Open the lab
Open the lab in any browser. No account, no password, no app store required.
Pick a puzzle type
Choose a room — spatial, figural, or quantitative reasoning — based on what your child wants to explore.
Practice a few minutes
Short bursts are best. A few minutes of calm practice beats a long, stressful session.
One page per reasoning skill.
Each skill the Lab practices has its own parent-readable page — what the skill is, worked examples, and a link straight into the matching room.
Transition to structured practice.
The Practice Lab is a great starting point. When you're ready for a finite, structured, editorially-reviewed workbook to hold in your hands, we have that too.
