Connect place, order, factors, signed operations, priority rules and inverse checks.
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.
🎓 You are learning to: Connect place, order, factors, signed operations, priority rules and inverse checks.
This studio works in three steps:
Each mission is a focused challenge from the menu at the top.
Select the option you could defend — which rule, definition or representation supports it?
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
