Decimal Maths: Plan a Space Mission
Using decimals to explore the cosmos Year 6 Mathematics New Zealand Curriculum
Mission Briefing: Why Decimals Matter in Space
Precise calculations save lives in space Fuel measurements use decimals (litres) Food supplies calculated in kilograms Navigation requires exact coordinates Budget planning uses dollars and cents
Space Supply Shopping Challenge
Work in pairs to calculate costs Space food packs: $3.75 each Oxygen tanks: $15.40 per kg Calculate total costs and change Use estimation to check answers
Quick Calculation Check
If oxygen costs $15.40 per kg... How much for 2.5 kg? Estimate first, then calculate! What strategy will you use?
Mission Measurements
{"left":"Mass: Astronaut gear weighs 12.75 kg\nCapacity: Water tank holds 8.5 litres\nLength: Solar panel is 3.2 metres long","right":"Temperature: Space suit maintains 21.5°C\nDistance: Orbit altitude is 408.5 kilometres\nTime: Mission duration is 6.25 days"}
Navigation and Geometry in Space
Spacecraft turns measured in degrees Right turn = 90 degrees Half turn = 180 degrees Plot coordinates on space grid Use decimals for precise locations
Space Mission Budget Challenge
Total budget: $100.00 Calculate if you can afford: 6 food packs at $3.75 each 2.5 kg oxygen at $15.40/kg 3 tool kits at $12.80 each Write as an inequality: Cost ≤ $100
Mission Accomplished!
