Represent decimals to tenths less than one with area models. Convert between fraction, decimal, and unit form.
While “mathematicians and scientists often read 0.5 aloud as ‘zero point five’ or ‘point five,’” refrain from using this language until you are sure students have a strong sense of place value with decimals (NF Progression, p. 15).
Use what you notice in (a) to write a similar sentence that starts “1 one is the same as…”
Use what you just learned in (a) and (b) above to fill in the missing place value.
a. Imagine the following model as a zoomed-in ones cube. Partition and shade it to represent the following fractions.
i. 2 tenths
ii. 3 tenths
iii. 5 tenths
b. Fill out the following table.
