  • 10. Week 4
    Focus Skill
    This week’s focus skill is rounding,
    ordering, and solving problems
    using decimals to the thousandths
    place
  • 11. Focus Skill
    Let’s review rounding with
    Decimals:
    1) 578.67
  • 12. Focus Skill
    Now review how to compare decimal numbers. Remember, we use < > = to compare.
    2) 9 O 7.2
  • 13. Focus Skill
    Compare:
    7 O 7.00
    101 O 100.97
  • 14. Focus Skill
    Now we will order decimal numbers. Make sure you know if it is smallest to largest or largest to smallest.
  • 15. Focus Skill
    Let’s try one:
    Order from least to greatest:
    4.5; 8; 4.35; 11; 1.3
  • 16. Focus Skill
    Order from greatest to least:
    21; 15.12; 89.1; 37.99; 21.5
  • 17. Focus Skill
    Now we will add and subtract with decimals.
    Write the rule in your notes:
    When adding or subtracting decimals, line up the decimals
  • 18. Focus Skill
    Let’s try one together:
    8.3 + 6.7 =
    8.3
    + 6.7
    .
    Line up the decimals
  • 19. Focus Skill
    You try one:
    7.3 + 11.4 =
    .
    + .___
    .
    Line up the decimals
  • 20. Focus Skill
    You try one:
    61.1 + 25.93 =
    .
    + .___
    .
    Line up the decimals
    Add missing zeroes
  • 21. Focus Skill
    You try one:
    44 + 1.8 =
    .
    + .___
    .
    Line up the decimals
    Add missing zeroes
  • 22. Focus Skill
    Subtraction works the same way:
    8.3 - 5.1 =
    8.3
    - 5.1
    .
    Line up the decimals
  • 23. Focus Skill
    You try one:
    5.2 - 2.4 =
    .
    + .___
    .
    Line up the decimals
  • 24. Focus Skill
    You try one:
    90 - 15.7 =
    .
    + .___
    .
    Line up the decimals
    Add missing zeroes
  • 25. Focus Skill
    You try one:
    10.8 – 8.21 =
    .
    + .___
    .
    Line up the decimals
    Add missing zeroes
  • 26. Focus Skill
    Your turn:
    Line up the decimals
    Add missing zeroes
    4.5 + 2.4 =
    7.2 – 5.5 =
    12 + 6.6 =
    9.1 – 6 =
    77 + 8.12 =
