FAQ
What two conversion facts do students need for this worksheet?⌄
100 cm = 1 m and 10 mm = 1 cm — from these, students can derive 1000 mm = 1 m for direct meter-to-millimeter conversions.
How do students handle a conversion spanning all three units, like meters to millimeters?⌄
Multiply meters by 100 to get centimeters, then multiply by 10 to get millimeters — or directly by 1000 — showing that the base-10 system makes multi-step conversions manageable.
How does working across three metric units build number sense?⌄
Students see that the same measurement can be expressed as 1.5 m, 150 cm, or 1500 mm — reinforcing that number size depends on the chosen unit, not the physical quantity.
