  7. Find the Product 3 minutes 5.NBT.7 4 x 3 = 4 x 0.2 = 4 x 3.2 =

  8. 4 x 3.21 = 9 x 0.1 = 9 x 0.03 =

  9. 9 x 2.13 = 4.021 x 4 = 5 x 3.2375 =

  10. Compare Decimal Fractions 3 minutes 3.NF.3d > < = 13.78 13.86 0.78 78 100

  11. < > = 439.3 4.39 5.08 fifty-eight tenths thirty-five and 9 thousandths 4 tens

  12. Application Problem (7 minutes) Louis buys 4 chocolates. Each costs $2.35. 
Louis multiples 4 x 235 and gets 940. Place the 
decimal to show the cost of the chocolates and 
explain your reasoning using words, numbers 
and pictures.

  13. Concept Development (28 minutes)

  14. Problem 1 Dividing decimals 0.9 3 = tenths

  15. Problem 2 0.24 4 = hundredth

  16. Problem 3 0.032 8 = thousandths

  17. Problem 4 1.5 5 = tenths

  18. Problem 5 1.05 5 = hundredth

  19. Problem 6 3.015 5 = thousandths

  20. Problem 7 Compare the relationships How are they alike? 4.8 6 = 0.8 48 6 = 8 How can help you 
solve the other problem? 48 6 = 8

  21. Problem 8 How are they alike? 4.08 8 = 0.51 408 8 = 51 How can help you 
solve the other problem? 408 8 = 51

  22. Problem 9 How are they alike? 63,021 7 = 9,003 63.021 7 = 9.003 How can help 
you solve the other problem? 63,021 7 = 9,003

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

  24. Student Debrief (10 minutes) In 2a, how does your understanding of whole 
number division help you solve the equation with 
a decimal? In 4a, what mistake is being made that would 
produce 5.6 7 = 8 Correct all dividends in #4 so that the 
quotients are correct. Is there a pattern to the 
changes that you must make? Is there another decomposition of the dividend 
in 2c that could have been useful in dividing 
by 2? What about in 2d? Why or why not? 4.221 7 = ______. Explain how you 
would decompose 4.221 so that you only 
need knowledge of basic facts to find the 
quotient. When decomposing decimals in different ways, 
how can you tell which is the most useful?
