What does this 4th grade measurement unit cover?

It introduces metric and customary units of length, mass, weight and capacity, and how to convert a larger unit into a smaller one by multiplying. By the end a child should know that 1 foot is 12 inches and 1 kilometer is 1,000 meters, and solve simple conversion word problems.

How does RepeatWatch help with unit conversions?

Use Repeat one on a Numberock song to memorise conversion facts, or set an A–B loop on one worked conversion. Slow to 0.75× when a chart is on screen, save each unit type on keys 1–9, and use Stop after N loops for short sessions.
