Decimal Units (Capacity and Length) worksheets for Grade 3 (Elementary School)
What this unit covers
Relationships such as 1 L being 10 dL and 1 dL being 100 mL let a quantity in one unit be restated as a decimal in another. Conversions are lined up across capacity and length, from L to dL, cm to mm and km to m, together with moving between compound units and decimals, and word problems that rewrite before adding.
Multiplying where dividing was needed, or the reverse, turns 35 mm into 350 cm rather than 3.5 cm. If the number shrank while converting to a smaller unit, the direction is wrong. Confusing ten times with a hundred times also persists, as when 1 L 2 dL is written 1.02 L instead of 1.2 L.

- Learning Units of Length and Capacity — Build a Feel for Quantity Before Conversion
They know 1 L = 10 dL but freeze on the problem. Unit trouble isn't a memory gap — it's the missing feel for what 1 dL or 1 cm actually is. Here's how to build it at home.

"0.7 + 0.5 = 0.12". "2.5 × 10 = 2.50". Decimal errors come from place value. Here's how to teach 0.1 as "one tenth of 1", and what to secure at each grade.
