Fractions: Whole Numbers and Comparisons
Grade 3 Mathematics Learning about fractions and how to compare them
I Can Statements
I can write whole numbers as fractions I can compare fractions with the same denominator I can explain which fraction is greater or smaller I can use fraction vocabulary correctly
Whole Numbers as Fractions
The number 3 can be written as 3/1 Any whole number over 1 equals itself Practice: Write 5 as a fraction Use fraction strips to see why this works
Fraction Vocabulary
Numerator: the top number (how many parts) Denominator: the bottom number (total equal parts) Greater than: > Less than: < Equal to: =
Comparing Fractions: Same Denominators
{"left":"When denominators are the same, compare numerators\n3/7 vs 5/7\n3 is less than 5\nSo 3/7 < 5/7","right":"The bigger numerator wins!\n2/9 vs 7/9\n7 is greater than 2\nSo 7/9 > 2/9"}
Which is Greater?
Compare these fractions: 4/8 or 6/8 Think about the numerators! Use your fraction vocabulary to explain your answer
Hands-On Practice
Use fraction strips to create same denominator pairs Write 5 comparison problems Share with your partner Explain your reasoning using fraction vocabulary
