  2. KEY WORDS Fraction

  3. LESSON #1 Student outcome: I know what a fraction is A fraction is a number that stands for part of something. Usually a fraction represents one of the following: A number representing part of a set of items. A number representing part of a whole. Fraction Explaination http://www.coolmath4kids.com/fractions/fractions-01-what-are-they-01.html http://www.learnalberta.ca/content/memg/index.html?term=Division02/Fraction/index.html Fraction Interactive

  4. LESSON #1 Student outcome: I can find patterns in equivalent fractions Equivalent Fractions: fractions that are “equal” http://www.coolmath4kids.com/fractions/fractions-04-equivalent-01.html Page 167 – Connect (students will use colored counters to create = fractions) What fraction can you find for green squares? How many equivalent fractions can you find for green squares? Answer: 6/12 Answer: 3/6, 2/4, 1/2

  14. LESSON #1 Student outcome: I can find patterns in equivalent fractions Assignment Student Practice Book: Page 68-69 Textbook: Page 168 – 169 # 1, 5, 6a, 7a, 8a, 9

  15. LESSON #2 Student outcome: I can compare and order fractions Strategy #1: use fraction strips to compare

  16. LESSON #2 Student outcome: I can compare and order fractions Strategy #2: use fraction circles to compare

  17. LESSON #2 Student outcome: I can compare and order fractions Strategy #3: use a number line to compare

  18. LESSON #2 Student outcome: I can compare and order fractions Strategy #4: make equivalent fractions (same denominator) Comparing Fractions Game Compare 321342 5 4 3 5 6 3 http://www.thatquiz.org/tq/practice.html?fracineq

  19. LESSON #2 Student outcome: I can compare and order fractions Using all 4 strategies to compare fractions try and solve which fraction is greater. 3/4 or 7/8 Fraction strips 2. Fraction circles 3. Number line 4. Same denominator

  20. LESSON #2 Student outcome: I can compare and order fractions Strategy #4: make equivalent fractions (same denominator) Assignment Student Practice Book: Page 70-71 Textbook: Page 172 – 173 # 2, 3, 5, 7, 10, 12

  21. LESSON #3 Student outcome: I can understand a problem and pick a strategy to solve it. Strategies Toolkit Connect (Page 174) Practice (Page 175) # 1, 2, 3

  22. LESSON #4 Student outcome: I can relate fraction to decimals with denominatorsof 10 and 100 Try to make the fraction have a denominator of 10 or 100 5/10 is 5 tenths or 0.5 9/100 is 9 hundredths or 0.09

  23. LESSON #4 Student outcome: I can relate fraction to decimals with denominatorsof 10 and 100 What happens when the denominator is not 10 or 100? Make an equivalent fraction that does have a denominator of 10 or 100 2/5 is equal to 4/10 or 40/100 2/4 is equal to 50/100 (any fraction with a denominator of 10) 3/4 is equal to 75/100

  24. LESSON #4 Student outcome: I can relate fraction to decimals with denominatorsof 10 and 100 How do you change a decimal to an equivalent fraction? 0.45 = 0.8 = 0.67 = 0.10 =

  26. LESSON #5 Student outcome: I can order and compare decimals to hundredths Lets find fractions that and their equivalent decimals using the chart below Fraction/Decimal Game http://www.venturaes.com/curriculum/HOM3/HOM3_Activity_8.html

  27. LESSON #5 Student outcome: I can order and compare decimals to hundredths Lets divide the number line into equal parts (or create benchmarks) Halves Thirds Fourths Fifths

  28. LESSON #5 Student outcome: I can order and compare decimals to hundredths Explore Page 180 (work with students through explore section) Connect Page 180-181 (discuss with students) Assignment Student Practice Book Page 74 – 75 Textbook Page 181 – 182 # 1, 3, 4, 6, 7,

  29. LESSON #6 Student outcome: Iwill understand thousandths

  30. LESSON #6 Student outcome: Iwill understand thousandths How would we say each decimal and write it as a fraction? Ex #1 0.123 Ex #2 0.056 Ex #3 0.009 Ex#4 1. 450 Ex #5 14.773

  31. LESSON #6 Student outcome: Iwill understand thousandths How would we say each fraction and write it as a decimal? Ex #1 123 1000 Ex #2 56 1000 Ex #3 9 1000 Ex#4 450 1000 Ex #5 1209 1000

  32. LESSON #7 Student outcome: Iwill be able to order and compare decimals Order numbers from least to greatest = (smallest to biggest) Order numbers from greatest to least = (biggest to smallest) Ex: 0.002, 0.89, 0.020, 0.704

  33. LESSON #8 Student outcome: Iwill be use decimals when I measure Review • What kind of comparisons can you make betweenmetres (m) centimeters (cm) and millimeters (mm)? • 1m = mm • 1m = cm • 1mm = m • 1cm = m • 1cm = mm • 1mm = cm

  34. LESSON #8 Student outcome: Iwill be use decimals when I measure Review • Solve • 50cm = mm • 83m = cm • 543mm= m • 789cm = m • 34.6mm = cm

  35. LESSON #9 Student outcome: I can relate decimals and fractions to division We need to split 5 pizzas among your 3 friends. How do we do this? How much does each person get?

  36. LESSON #10 Student outcome: I can estimate sums and differences using decimals Things to remember: ALWAYS line up the decimals Empty place values can be filled in with a ZERO Example: Find the sum of 3.56 and 1.009

  37. LESSON #10 Student outcome: I can estimate sums and differences using decimals Things to remember: ALWAYS line up the decimals Empty place values can be filled in with a ZERO Example: Find the difference between 12.898 and 1.3

  38. LESSON #11 Student outcome: I can add decimals Remember the 2 rules: Ex: 26.79 Ex: 345.8 + 2.60 + 23.14 20.00 8.00 1.30 0.09 29.39
