Question image

Your teacher gives you four square pieces of paper and asks you to cut each piece of paper into 4 equal-sized pieces. You try these four patterns for your cuts. Which squares show equal-sized pieces?

1

A, B, and D only, not C

2

A, B, C, and D

3

A and D only, not B or C

3

All four are the same size!

All four square patterns are divided into equal-sized pieces. Pattern A is divided into four equal-sized rectangles. Pattern B is divided into four equal-sized squares. Pattern C is divided into two rectangles and two squares and all four parts are equal in size. Pattern D is divided into four equal-sized rectangles.

Problem 1

  • Meghan, Zoe, Jack, and Gabriel are sharing these pieces of watermelon.

  • Some of the friends like watermelon more than others.

  • Meghan wants to eat the most pieces of watermelon.

  • Jack wants to eat the same number of pieces as Gabriel.

  • Zoe wants to eat more pieces than Gabriel.

Meghan eats 3 pieces of watermelon.

There are 7 pieces of watermelon. Meghan wants to eat the most pieces of watermelon. Jack and Gabriel want to eat the same number of pieces, and Zoe wants to eat more pieces than Gabriel. Give Jack and Gabriel 1 piece each, give Zoe 2 pieces, and then there are 3 pieces left for Meghan.

Problem 2

  • Tony and his family visit a state park.

  • They grill 5/6​ pound of hamburger for lunch.

  • The hamburger is made into 1​/6​-pound patties.

  • How many hamburger patties do Tony and his family have?

This is what 5/6 looks like.

If each hamburger is 1/6 of a pound, how many hamburgers do you think they could make?

New vocabulary term: Unit Fraction

unit fraction tells the part of a whole that each piece represents. The numerator of a unit fraction is always 1.


For this problem, the hamburger is made into 1/6​​-pound patties. 1/6​​ is a unit fraction.The unit fraction represents 1 hamburger patty, or 1/6​​ pound of hamburger.

Multiple Choice

What addition equation can you write to model the weight of hamburger as a sum of the weights of the patties? Remember, they have 5/6 pound of meat and 1/6 pound of meat makes a hamburger.

1

5/6 + 1/6 = 6/6

2

1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6

3

3/6 +3/6 = 6/6

13

We would use 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 5/6

  • Each patty weighs 1/6​​ pound, and there is a total of 5/6​​ pound of hamburger.

  • Use the unit fraction to write an addition equation equal to the total weight of the hamburger.

  • 1 + 1 + 1 + 1 + 1 = 5, so the same goes for fractions with common denominators.

  • REMEMBER THAT DENOMINATOR MEANS THE BOTTOM, OR THE RIGHT NUMBER!

Question image

What is a way we can break 7/12 into pieces so Tony's family can walk their dog? Use an addition equation.

17

Here are some ways we can break up 7/12 into different addition equations:

  • 1/12 + 6/12 = 7/12

  • 2/12 + 5/12 = 7/12

  • 3/12 + 4/12 = 7/12
