Perfect for retrieval, revision, or challenge tasks!
This Thinking Hard Challenge Grid uses PiXL’s higher-order strategies to help students deeply engage with specification content
Designed to stretch and challenge learners of all abilities, it’s perfect for starters, plenaries, cover work, independent study, or revision stations. Ai was used to help make these resources.
Example Tasks:
Reduce It – Strip information down to the essentials

Spot the Mistake – Identify and correct misconceptions

Connect 4 – Link keywords and explain their relationship

Always/Sometimes/Never – Justify your reasoning

Apply It – Real-world scenario questions
