Math Games: Metric Lenghts

Walt: Create and use appropriate units and devices to measure length, area, 

volume and capacity, weight (mass), turn (angle), temperature, and time.

In this game I'm matching the measurements of each one that is related. I found this easy because what I knew was 100 cm=1 metre and 1000 metres= 1 kilometres, 1000 millimetres= 1 metre and 10  millimetres= 1 centimetre. But level 5 was getting harder than I thought, they used 200 metres, millimetres, centimetres and kilometres. Next I think I would want to learn more about this so I can become more knowledgeable about lengths. So it can stick in my brain.
