Turn an expanded notation expression into one decimal number. Use place value to decide which digits go in the ones, tenths, hundredths, and thousandths places. Combine whole-number parts and decimal parts correctly when writing the number in standard form. Write decimals with zeros in the right places when a place value is missing.

Use place value to decide which digits belong in the ones, tenths, hundredths, and thousandths places. Write decimals correctly with a decimal point and zeros when a place value is missing. Combine the parts of an expanded form by adding them to make a single decimal number.

Break a decimal number into the value of each digit and write it as a sum. Match each digit to its correct place value, including tenths, hundredths, and thousandths. Use zeros as placeholders so the expanded notation still shows the correct value. Read a decimal number and explain what each part is worth in expanded form.

Break a decimal number into the value of each digit using place value. Write a number in expanded form using addition to show how the parts make the whole. Read and interpret digits in tenths, hundredths, and thousandths places. Include zero place values correctly when writing expanded form.

Read decimal numbers and say them correctly using place-value words like tenths, hundredths, and thousandths. Write a decimal number in word form using the word "and" for the decimal point. Spell number words correctly when writing decimals in words. Match each digit in a decimal to its correct place value so the word form says the right amount.

Turn a decimal written in words into the correct number with a decimal point. Use place value words like tenths, hundredths, and thousandths to decide which digits go where. Write decimals correctly when the words include zeros, like “three and five thousandths.” Read the word “and” as the decimal point when writing the number.

5nbt3a
Shade a 10 by 10 grid to show a decimal. Turn tenths and hundredths into a number of squares. Represent a decimal with a model.
5nbt3a
Write the same amount as tenths and as hundredths. See that one tenth is ten hundredths. Recognize ten tenths as one whole.
