Grade 4 G/T Fractions

5.NF.3

About the Math

Full Standard

Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers (e.g., by using visual fraction models or equations to represent the problem). For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?

 

Learning Targets (I can)

  • Explain that fractions represent division with representations (i.e. 3 hoagies shared by 4 people is 3/4 of a hoagie per person)
  • Represent word problems that involve division of whole numbers.
  • Write an equation for a word problem (i.e. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? 50 ÷ 9 = ? or 50/9 = ?)
  • Represent and explain a remainder as a fraction. 

 

About the Math

When fractions represent division, the denominator acts as the divisor and the numerator is the multiplier. This means that 3/4 is three times what you get when you divide a whole into four parts. So if you were to divide 3 pancakes among 4 people ( 3 ÷ 4), each person would get 3 pieces or 3/4 of a pancake. Students need to understand that numerator is the same as the dividend and denominator is the same as the divisor. Essential vocabulary for this standard includes: mixed number, improper fraction, dividend, divisor, quotient, numerator, and denominator.

Instructional Tasks

TASKS

These tasks can be used with small group or whole group instruction.

  • What is the relationship between 7 divided by 8 and ⅞?
  • How do the numerator and denominator of a fraction compare with the dividend and divisor of a division expression?
  • Every kid in the car on its way to swim practice got ¾ of a sub. There were four kids. How many subs did the mom get?
  • Why do some people write ⅘ when they mean 4÷5 ?
  • Draw pictures or build models to show why ⅛ = 1 ÷ 8, why 8/3 = 8 ÷ 3 =, and why ⅜ = 3 ÷ 8
  • 15 friends want to share 3 watermelons equally. What fraction of a watermelon will each friend get?

 

 

SLIDE-BASED TASKS 

 These links are HCPSS created instructional tasks. These tasks are provided in Google slides. These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first (often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
