Grade 6 · original proportional contexts · no voice
Proportion workspace
Complete every proportion decision, then check your thinking.
This pilot aligns only to uncovered Year 6 records MAT-0203–MAT-0205. It samples percentage calculation/comparison, similar shapes with known/inferred scale factors and unequal sharing/grouping using fractions and multiples; it does not duplicate MAT-0202, complete the ratio/proportion unit, establish secure fluency, provide a lesson sequence or satisfy an assessment.
🎓 You are learning to: Calculate and compare percentages, scale similar shapes, and reason about unequal shares.
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: Calculate percentages of measures · Use percentages for fair comparison · Use known and inferred scale factors · Solve unequal sharing and grouping
