Measurement, Conversion, and Line Plots
Aligned to 4.MD.A.1 — Common Core State Standards for Mathematics.
What this lesson teaches
Units in the same system are related, so you can convert from a larger unit to a smaller one by multiplying. For example, since 1 foot is 12 inches, 3 feet is 3 times 12. You can also display fractional measurements on a line plot.
Worked example
Convert 4 feet to inches. There are 12 inches in a foot, so 4 times 12 equals 48 inches.
Practice questions
- How many inches are in 5 feet?
- How many minutes are in 3 hours?
- Convert 2 hours to seconds.

Medición, Conversión y Diagramas de Puntos
Las unidades del mismo sistema están relacionadas entre sí, por lo que puedes convertir de una unidad mayor a una menor multiplicando. Por ejemplo, como 1 pie equivale a 12 pulgadas, 3 pies equivalen a 3 veces 12. También puedes mostrar medidas con fracciones en un diagrama de puntos.
Ejemplo: Convierte 4 pies a pulgadas. Hay 12 pulgadas en un pie, entonces 4 por 12 es igual a 48 pulgadas.
