Today in class students took an adding, subtracting, multiplying, and dividing decimals quiz.
Today in class students told me that you do not have to line up the decimals when multiplying or dividing them. In fact, you will mess up your answer Mrs. Jankowski! Again. the only thing new here is using positive and negative numbers. The same rules for multiplying and dividing integers applies here:
+ times + = + + divided by + = + - times - = + - divided by - = + + times - = - + divided by - = - - times + = - - divided by + = - Answers to HW: 11. - 5.1 16. - 11.478 12. 0.8 17. 37.3 13. - 6.5 18. 0 14. - 12.8 19. 15.18 15. 2.7 20. - 15.36 Today in class students told me that you have to line up the decimal in order to add and subtract them. They learned that when combining a positive and a negative decimal - you are really finding the difference between them. The sign of the answer, positive or negative, comes from the bigger number.
Answers to HW: 1. - 4.3 6. - 3.17 2. 6.07 7. 10.2 3. - 0.2 8. - 3.47 4. - 5.19 9. 16.9 5. 5.005 10. - 4.8 In class today students practiced converting fractions to decimals and decimals to fractions as they determined their value and placed them in order from least to greatest. We worked on problems #12 - 15, 20 - 22, 26 - 34 on p. 176 in a textbook in class. Students copied down, or took a picture of, the problems they did not yet complete to do for homework.

In class today students practiced converting fractions into decimals and decimals into fractions. We also learned a trick for turning repeating decimals into fractions: just put the repeating number(s) over 9(s). The video link will show you how the math works. Answers to HW: 13. 2 1/5 19. 1/3 14. 1 3/5 20. 1/11 15. 2/25 21. 7/9 16. 27/100 22. 46/99 17. 1 19/25 23. 1/200 18. 5/33 24. 2/5 In class today students converted fractions to decimals by reading the decimal and writing the number over the 10, 100, or 1000 place value in the denominator. We also reviewed the Integers test today which has been completed and corrected.
Today in class students added to their knowledge of converting fractions to decimals. In addition to reading the fraction 3/10 as "three tenths" and finding the equivalent fraction with a denominator of 10, 100, or 1000, today we divided the fractions to find the decimal form. We practiced 12 problems in our groups of three today.
Answers to the problems: 1-6 were on the board in class 7. 0.54 repeating 8. 0.14 9. 4.216 10. 0.35 11. 0.009 repeating 12. 0.008 In class today students reviewed fractions (part of a whole), place value, and began to convert fractions to decimals by reading the fraction and assigning the numbers by their place value and also by converting the fraction into one with a 10, 100, or 1000 in the denominator and then reading it.
