Maryland Math 4.GR.A.1
The Standard
Apply the relationship between measurement units within a given measurement system (customary: in, ft, yd, oz, lb, sec, min, hr; metric: cm, m, km, g, kg, mL, L) to convert measurements from a larger unit to smaller unit.

What This Standard Means
What Students Need to Do
- Students change measurements from larger units to smaller units within the same system. They multiply by the number of smaller units in one larger unit and label the answer.
What Mastery Looks Like
- A student can turn 3 yd into 9 ft or 108 in and show the steps. They can also turn 2 kg into 2,000 g using the correct conversion factor.
Common Misconceptions
- Students may divide instead of multiply when changing to smaller units. They may use 10 for every metric conversion or confuse 3 feet per yard with 12 inches per foot.
How to Assess It
- Exit ticket: Convert 4 yd to ft and 3 L to mL. Show the multiplication and label both answers.

Ways to Teach It
Give pairs a yardstick and a 36-inch paper strip to mark each foot and count how many inches make one yard.
Have students write one sentence explaining why 2 kg is 2,000 g rather than 20 g, using a multiplication equation.
Play conversion bingo: call out 3 hr, 2 lb, or 5 m, and students cover 180 min, 32 oz, or 500 cm.
Show a 2 L soda bottle and have students write its capacity in milliliters on a party supply list.
