These lessons, with videos, examples and solutions, help Grade 4 students learn the 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), …

### Suggested Learning Targets

• I can describe the relative size of units (100 m are in a km, 100 cm are in a m, 16 ounces are in a pound).
• I can represent a larger unit with smaller units (36 m = 360 cm, 4 yards = 48 inches).
