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 =
