13. Decimals Operations using the Base-10 models Addition: 1.23 + 0.56 1. 0.7 0.09 1.79

14. Decimals Operations using the Base-10 models Subtraction: 1.79 - 1.52 0.27

15. Decimals Operations using the Base-10 models Your Turn! Add 0.74 and 0.58 1.32

16. Decimals Operations using the Base-10 models Multiplication: 0.24 x 5

17. Decimals Operations using the Base-10 models Multiplication: 0.24 x 5 1.20

18. Decimals Operations using the Base-10 models Division: 4.35 ÷ 3

19. Decimals Operations using the Base-10 models Division: 4.35 ÷ 3 =1.45

20. Decimals Operations using the Base-10 models Your Turn! Choose either... Multiplication: 1.2 x 3 Division: 3.28 ÷ 4

21. Decimals Operations using the Base-10 models Your Turn! Choose either... Multiplication: 1.2 x 3 = 3.6 Division: 3.28 ÷ 4

22. Decimals Operations using the Base-10 models Your Turn! Choose either... Multiplication: 1.2 x 3 Division: 3.28 ÷ 4 = 0.82

23. Decimals Operations using the Base-10 models Multiplying two decimals: 0.3 x 1.2 (3/10 of 1 and 2/10) 1.2 0.3 = 0.36

24. Decimals Operations using the Base-10 models Dividing two decimals: 1.8 ÷ 0.6 (1 and 8/10 split into groups that are 6/10 in size) 1.8 0.6 = 3 0.6

25. Decimals Operations using the Base-10 models Your Turn! Choose either... Multiplication: 2.5 x 0.8 Division: 3.6 ÷ 0.4

26. Decimals Operations using the Base-10 models Your Turn! Choose either... Multiplication: 2.5 x 0.8 = 2.0 Division: 3.6 ÷ 0.4

27. Decimals Operations using the Base-10 models Your Turn! Choose either... Multiplication: 2.5 x 0.8 = 2.0 Division: 3.6 ÷ 0.4 = 9

30. Percents Our goal is to help students understand find percent of a number..01

31. Percents 1% = 10%

32. Percents.01 Percents 1% = 14% = 57% = 38%

33. Percents A school in Los Angeles has a student population of 450 students. 14% of the students are receiving free or reduced lunch. How many students are going to receive free or reduced lunch? = 45 students = 18 students 45 + 18 = 63 students 450 ÷ 100=4.5
