The Thinking Tools Library
A thinking tool is a small mental move a child can reuse for life: a question, a check, a rule that keeps working long after the lesson is over. Below are 16 of the tools Parker Smart Kids teaches, grouped by the six thinking skills we score, each with a plain-language guide for using it with your own child.

Frequently asked questions
What is a thinking tool?
A thinking tool is a short, reusable mental move - a question or check a child can apply to almost any situation, like asking who said a claim and how they could know it. Unlike a fact, a thinking tool keeps working long after the lesson that taught it.
At what age can children learn critical thinking?
Children begin reasoning about cause, fairness, and evidence as early as age 8, and the capacity deepens through the teen years. The key is to practice concrete thinking tools at the right developmental level rather than waiting for an abstract "critical thinking" class later.
How do you actually teach critical thinking at home?
You teach it the way you teach any skill: with small, repeated practice on real situations. Pick one thinking tool, name it out loud, and use it together on something your child already cares about - an ad, a rumor, a choice - a few times a week.
How is this different from memorizing facts?
Facts answer one question; thinking tools help a child answer questions they have never seen before. Parker Smart Kids is built entirely around portable thinking tools, scored across six reasoning dimensions, so the skill transfers beyond any single lesson.
Your child can practice a tool like this every day
Parker Smart Kids turns reasoning into a 15-minute daily habit: 1,800 age-targeted lessons across six thinking dimensions, built by Guinness World Records Puzzle Master Timothy E. Parker.
