  14. Application Problem (8 minutes) Jordan measures a desk at 200 cm. James 
measures the same desk in milliliters, and Amy 
measures the same desk in meters. What is 
James measurement in milliliters? What is 
Amy's measurement in meters? Show your 
thinking using a place value mat or equation 
using place value mat or an equation with 
exponents.

  15. Concept Development (30 minutes)

  16. Opener three thousand forty seven standard form: _____________________

  17. Problem 1 Represent in standard and unit form. one thousandths one thousandth = 0.001 = 1 1000 1 = 1 x 1 1000  1000 0.001 = 1 x 0.001 1 thousandths notes Write in digits on place value chart. standard form: ________________________ as a fraction: ________________________ expanded form: using fractions ________________________ using decimals ________________________

  18. If you had 3 copies of 1 thousandths, how many thousandths is that? three thousandth = 0.003 = 3 1000 3 = 3 x 1 1000  1000 0.003 = 3 x 0.001 3 thousandths notes Write in digits on place value chart. standard form: ________________________ as a fraction: ________________________ expanded form: using fractions ________________________ using decimals ________________________

  19. Problem 2 represent a number thousandths in standard form and unit form thirteen thousandth = 0.013 = 13 1000 13 = 1000  0.013 x 0.01+ 3 x 0.001 1 hundredth 3 thousandths 13 thousandths notes thirteen thousandths standard form: ________________________ expanded form: using fractions ________________________ using decimals ________________________

  20. two hundred seventy three thousandths standard form: ________________________ expanded form: using fractions ________________________ using decimals ________________________ are these the same? 2 tenths 73 thousandths 273 thousandths 27 hundredths 3 thousandths ???

  21. one and six hundred eight thousandths standard form: ________________________ expanded form: using fractions ________________________ using decimals ________________________

  22. Problem 3 Twenty-five and four hundred thirteen thousandths notes represent a number in word, expanded and unit form 413 1000 25.413 25 = 25.413 1 10 1 100 413 1000 1 1000 25 = 2 x 10 + 5 x 1 + 4 x + 1 x + 3 x word form:__________________________ decimal unit form: ____________________ other unit forms: _____________________ 25.413 = 2 x 10 + 5 x 1 + 4 x 0.1 + 1 x 0.01 + 3 x 0.001 2 tens 5 ones 4 tenths 1 hundredths 3 thousandths 25 ones 413 thousandths

  23. 12.04 word form:__________________________ decimal unit form: ____________________ other unit forms: _____________________

  24. 9.495 word form:__________________________ decimal unit form: ____________________ other unit forms: _____________________

  25. Problem 4 write the standard, expanded and unit forms write the expanded and unit forms 
of each number 404 1000 four hundred four thousandths = = 0.404 404 1000 1 10 1 1000 = 4 x + 4 x four hundred four thousandths four hundred and four thousandths notes 4 1000 four hundred and four thousandths = 400 = 400.004 0.404 = 4 x 0.1 + 4 x 0.001 4 tenths 4 thousandths 4 1000 1 1000 400 = 4 x 100 + 4 x 400.004 = 4 x 100 + 4 x 0.001 notes 2

  26. write the expanded and unit forms 
of each number two hundred two thousandths nine hundred and nine tenths

  27. Problem Set (10 minutes) Do Your Personal Best (Complete independently!)

  28. Student Debrief (10 minutes) When might expanded form be useful as a 
calculation tool? Which tasks in #1 are alike? Why? What is the purpose of writing a decimal 
number in expanded form using fractions? 
What was the objective of our lesson today? How is expanded form related to the standard 
form of a number? Compare your answers to #1 c and d. What is 
the importance of the word and when naming 
decimals in standard form?
