This pilot aligns only to uncovered Key Stage 3 records MAT-0277–MAT-0279. It samples related-unit conversion, scale drawings, a fictional map and quantity fractions. It does not establish conversion fluency or general proportional reasoning. It does not complete the ratio, proportion and rates-of-change unit, provide a lesson sequence or satisfy an assessment.
🎓 You are learning to: Convert related units, interpret drawings and maps, and compare quantities as fractions.
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: Convert freely among related standard units · Interpret and apply a scale drawing · Use a fictional map scale · Express one quantity as a fraction of another
