Complete every decision, then check your reasoning.

This pilot aligns only to uncovered Key Stage 3 records MAT-0245–MAT-0250. It samples place/order, prime structure, signed rational operations, priority and inverse checks. It does not establish fluency or secure understanding over time. It does not complete the number unit, provide a lesson sequence or satisfy an assessment.

How “Grade 7 Number Structure Studio” works

🎓 You are learning to: Connect place, order, factors, signed operations, priority rules and inverse checks.

This studio works in three steps:

  1. 🎯 Choose a mission

    Each mission is a focused challenge from the menu at the top.

  2. 🧠 Decide and justify

    Select the option you could defend — which rule, definition or representation supports it?

  3. 🔁 Check, reflect, improve

    If the check finds an error, work out why before moving on. Finish by choosing the reason that shows how you know.

Missions in this studio: Connect place value and real-number order · Use prime factorisation, HCF and LCM · Operate with signed integers, decimals and fractions · Audit priority and inverse-operation reasoning

💡 Aim to explain your method, not just your answer.
