Mental Math Warm‐Up

• One hundred four minus sixty seven = ?

• Twenty seven times twelve = ?

• Two hundred thirty six divided by half = ?

What’s the Plan?

• Discussion: What is at the heart of “I hate fractions”?

• Understand the basics of the progression of fraction sense across grades K‐5

• Believe in the power of “Fractionese” (MP3)• Experience some activities designed to help students make sense of fractions through language and math tools (MP1 & MP5)

*We won’t have time to cover every standard.

Mental Math Warm‐Up

• One hundred four minus sixty seven = 37

• Twenty seven times twelve = 324

• Two hundred thirty six divided by half = 118…or maybe 472?

Why do students say “I hate fractions”?

• 1 minute think/write time

• Timed Pair Share – 30 seconds each

• Whole‐class share

Page 6: Fraction Ghostbusters.pptx [Read-Only] · Fraction Ghostbusters. ... 3‐5 NUMBER AND OPERATIONS ‐ FRACTIONS 3 ... color it on your pattern block triangle paper ...

Why do students say “I hate fractions”?

• 1. They don’t understand fractions.• 2. They feel stupid.• 3. They haven’t grasped the concept and/or become fluent at the skill.

• 4. Past experience with teachers that don’t love and/or understand fractions.

What is a fraction?

• As math teachers, we should have a pretty good idea of what a fraction is, right?

• In language any 3rd grader could understand, please define “fraction.”

What is a fraction?

• dictionary.com – 1. Mathematics. a number usually expressed in the form a/b. 

• a ratio of algebraic quantities similarly expressed. • 2. Chemistry. (in a volatile mixture) a component whose range of boiling point temperatures 

allows it to be separated from other components by fractionation. • 3. a part as distinct from the whole of anything; portion or section: The meeting started with 

a fraction of us present.

• merriam‐webster.com ‐ a : a numerical representation (as 3⁄4, 5⁄8, or 3.234) indicating the quotient of two numbers 

• b (1) : a piece broken off : fragment (2) : a discrete unit : portion

• mathisfun.com ‐ Part of a whole. 

• the bottom number (the denominator) says how many parts the whole is divided into 

• the top number (the numerator) says how many parts we have.

Kindergarten

• K.G.6 Compose simple shapes to form larger shapes.

Page 11: Fraction Ghostbusters.pptx [Read-Only] · Fraction Ghostbusters. ... 3‐5 NUMBER AND OPERATIONS ‐ FRACTIONS 3 ... color it on your pattern block triangle paper ...

First Grade

• 1.G.3 Partition circles and rectangles into two and four equal parts, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of.  Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal parts creates smaller shares.

Page 12: Fraction Ghostbusters.pptx [Read-Only] · Fraction Ghostbusters. ... 3‐5 NUMBER AND OPERATIONS ‐ FRACTIONS 3 ... color it on your pattern block triangle paper ...

Second Grade

• 2.G.3 Partition circles and rectangles into two, three, or four equal parts, describe the sharesusing the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

How can teacher‐leaders help?

• Spread the word among  your grade‐level colleagues.• Form a team for school/district vertical articulation.• Follow‐up, follow‐up, follow‐up.• Stress common use of fraction (and decimal) vocabulary: equal parts, whole, equivalent, “fractions are numbers”

• Don’t underestimate the power of estimation.• Understanding concepts is important for learning, but don’t forget the PRACTICE.  Fluency builds confidence!
