Measurement and Data
Solve problems involving measurement and conversion of measurements from a larger unit
to a smaller unit.
4.MD.1 Know relative sizes of measurement units within one system of units including km, m, cm;
kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in
a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table.
For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in.
Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...

 Students make more  Students make 1 or 2 errors  Part 1: 1 L = 1,000 mL; 1 L, 250 mL; 1,250
than 2 errors.
OR their explanation is not
mL; 1L, 750 mL= 1,750 mL; 2 L = 2,000
accurate.
mL; 2L, 400 mL = 2,400 mL; 2L, 756 mL;
2,756 mL; 3L = 3,000 mL
 Part 2: The sentence is logical and accurate.
