  1. Monday, April 9th Warm UP Please complete Warm up Find the quotient 1. 12.44 ÷ .2 2. 101.5 ÷ 5

  2. Direct Variation Test Reteach TOMORROW Retest WEDNESDAY

  3. Homework for the next two weeks Signature by WEDNESDAY This is your homework for the next two weeks! If you would like to work ahead then you may do so!

  4. When is the Math Superbowl Wednesday, April 25th

  5. Morning Tutoring Get pass from me if you want to come in and review!

  6. CRCT Review • Everyday for two weeks we will be covering 1-2 topics from this semester. • You will have a daily classwork grade. • Every Friday will be game day!

  7. Decimals and Fractions

  8. Part 1: Decimals What rules do you remember?

  9. Place Value Review

  10. Comparing & Ordering Decimals Steps Compare any TWO decimals at a time fill in zeroes so that each number has the same amount of place values Start at the left and compare the digits Look for the first place where they are different and rank them. Compare the next numbers using steps 1-4

  11. Real Life Application Tia reported on a star for her science project that has a magnitude of 11.3. Maven reported on another star that has a magnitude of 11.03. Which star has the smaller magnitude? 2. It takes Pluto 246.7 years to orbit the Sun, and it takes Neptune 164.8 years. Which planet takes longer to orbit the Sun?

  12. Partner Work Take the cards and put them from least to greatest

  13. Addition and Subtraction Riddle…. “Line up your decimals, add in your zeroes, find the sum, don’t be a bum…..line up your decimals, add in your zeroes, now it’s time to subtract, don’t get this out of wack”

  14. Adding 1. 3.45 + 6.12 + 12.09 2. 14.56 + 6.7912

  15. Subtracting 1. 14.03 – 6 2. 10.07 - 8.456

  16. Problem Solving Your mom gave you exactly $20.00 to spend at the Braves Game. One hot dog costs $4.45, a Coke costs$2, Nachos costs $5.60 and Dip’n Dots costs $4.59, what will the bill come to? Will you have enough money to buy all the food?

  17. Multiplying Decimals

  18. Recipe • Write your decimals vertically • Multiply your two numbers • Add up the decimal places to the right of each number. • Answer to step 3 is the amount of places you move your decimal to the left.

  19. Multiply, Then place the decimal point. 1 decimal place + 1 decimal place 2 decimal places Just Watch Find the product. 0.5  0.2 0.5  0.2 0.10

  20. You Try! 1. 12.6 x 2.1 • Write your decimals vertically • Multiply your two numbers • Add up the decimal places to the right of each number. • Answer to step 3 is the amount of places you move your decimal to the left.

  21. Practice makes perfect 2. .3 x .4 3. 1.34 x 2.5 4. .07 x .8 Complete and then help others in your group!

  22. What did Aladdin do wrong? Find the Product 3.4 x .03 3.4 .03 =102 =1.02

  23. Dividing Decimals

  24. Are you Ready for Some… Dividing A Monday Morning Party…. We’ve got Ms. Evans, the PP, and your minds, Let’s get these quotients started! M

  25. Remember! Vocab Review Quotient 0.15 0.75 5 Divisor Dividend

  26. Recipe • Set up divisor and Dividend • Look at the Divisor, move decimal place over to make a whole number • However many places you moved the decimal in step 2, you move the decimal in the dividend • Divide as you would with a whole number

  27. Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers. Just Watch #1 Find the quotient. 0.84 ÷ 3 0. 2 8 3 0.84 – 6 24 – 24 0

  28. Divide. Move decimal place over once for divisor Move decimal place over once for dividend Just Watch #2 Find the quotient. 5.2 ÷ 1.3 Dividend=5.2 1.3=Divisor 1.3 5.2 4 13 52 –52 0 5.2 ÷ 1.3 = 4

  29. 1 Move decimal over once in divisor Move decimal over once in dividend Divide. Let’s Try Together! Find the quotient. 1. 6.6 ÷ 1.1 1.1 6.6 6 11 66 -66 0 6.6 ÷ 1.1 = 6

  30. Practice makes perfect b. 0.72 ÷ .3 c. 2.96 ÷ .04 d. .32 ÷ 8 Complete and then help others in your group!

  31. What did Johnny Depp do wrong? Estimate 22.15 ÷ 5 4.43

  32. Part 2 Fractions

  33. 3 types of fractions • Simple: value less than 1 • Mixed: whole number and simple fraction. Value is greater than 1 • Improper: Numerator is greater than the denominator. No whole numbers. Value greater than 1.

  34. What did mickey do wrong?

  35. How do we add when we don’t have common denominators?!?

  36. Make EQUIVALENT Fractions!!!

  37. To add or subtract unlike fractions, first rewrite them as equivalent fractions with a common denominator. Remember! Fractions that represent the same value are equivalent.

  38. How do we do this? • You can use any common denominator. But it will be easier to find the least common denominator to add and subtract unlike fractions. • The least common denominator (LCD) is the least common multiple of the denominators.

  39. Time to + and -!!! Steps for unlike denominators • Find the LCD for the two denominators by looking for LCM • Make equivalent fractions by multiplying both the numerator and denominator by the same number (to get LCD) • Add the numerators, leave your denominator • If needed, simplify

  40. 11 13 9 3 11 22 3 __ __ __ __ __ __ __ 24 12 24 8 8 12 24 Just Watch - Multiples of 12: 12, 24, … Multiples of 8: 8, 16, 24, … The LCD is 24. – Write equivalent fractions with a common denominator. – Subtract.

  41. 4 5 7 1 4 12 1 __ __ __ __ __ __ __ 21 7 21 3 3 7 21 Let’s Try Together! - Multiples of 7: 7, 14, 21, … – Multiples of 3: 3, 6, 9, 12, 15, 18, 21, …The LCD is 21. – Write equivalent fractions. Subtract.

  42. What did CL do wrong?

  43. 1 1 3 5 1 1 1 7 3 5 13 1 1 1 3 __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ 2 6 4 6 3 12 24 4 8 8 6 24 8 8 12 cup Pick 3 Add or subtract. Write each answer in simplest form. 1. + 2. – 3. – 4. + 5. Bonnie is making oatmeal bars and the recipes calls for cup of brown sugar. If she has cup of brown sugar, how much more does she need?

  44. How do we add and subtract Mixed numbers?

  45. Add your bigs Then Add your smalls

  46. 2 1 5 8 2 3 1 __ __ __ __ __ __ __ 4 12 3 3 12 4 12 Just Watch 5 – 1 The LCD of 3 and 12 is 12. 5 5 Write equivalent fractions with a denominator of 12. –1 – 1 ______ ______ Subtract the fractions and then the whole numbers. 4

  47. 1 3 1 7 1 6 3 __ __ __ __ __ __ __ 7 14 2 2 14 7 14 You try! 4 – 1 4 4 The LCD of 2 and 7 is 14. Write equivalent fractions with a denominator of 14. –1 – 1 ______ ______ Subtract the fractions and then the whole numbers. 3

  48. Who did the problem correctly?

  49. Regrouping

  50. Renaming fractions I need to rename to have enough fourths to take away from Here’s how you do it! • Subtract 1 from your big • add your numerator to your denominator • Answer to step 2 is your new numerator
