Instructions

Play through this interactive game to learn about Read And Write Decimals To The Thousandths. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Use tenths, hundredths, thousandths, 0.n, 0.nm, 0.nmt to name decimal numbers to the tenths (the last digit to the right is in the tenths place value), hundredths (the last digit to the right is in the hundredths place value) and thousandths (the last digit to the right is in the thousandths place value).

Interchange between decimal number names to numerals and expanded form.

Compare decimals by comparing place value or expanding to compare (Is nine and fifty two tenths = to 9.52? No, because 9 + 52/10 = 9 + 50/10 + 2/10 = 9 + 5 + 2/10 = 14 2/10. 9.52<14 2/10.)

Express decimal numbers in word form.

A multi-digit number is expressed in expanded form when it is written as a sum of single digit multiple powers of ten (ex: 256.23 = 2 x 100 + 5 x 10 + 6 x 1 + 2 x 1/10 + 3 x 1/100).

What are the place values to the right of the decimal? What are the denominators of the decimals you used in the game if they are written as fractions? How do you use your knowledge of place value to write numbers including decimals in expanded form? What trick did you use to place decimals from smallest to largest on the number line?
