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