Math Grade 5 Quiz Reading and Writing Decimals to Thousandths Using Various Forms – 5.NBT.A.3.A

Under this standard, students are expected to understand how to read and write decimals to the thousandths place using base-ten numerals, number names, and expanded form. This includes recognizing how the value of a digit changes depending on its position in a number and being able to break down a number into the sum of its parts using multiplication by powers of ten. For example, the number 347.392 would be broken down into 3 × 100 + 4 × 10 + 7 × 1 + 3 × (1/10) + 9 × (1/100) + 2 × (1/1000).
