Double facts are nothing additions in which a number is added to itself.

For example,

1 + 1, 2 + 2

Internalizing double facts are helpful building blocks in developing fluency in adding single digit numbers.

**Problem 1 :**

David has 10 candies. Daniel has the double of what David has. How many candies does Daniel have ?

**Solution :**

No. of candies that Daniel has = Double of what David has

= 10 + 10

= 20

So, Daniel has 20 candies.

**Problem 2 :**

John has 12 cookies. Jose has the double of what John has. How many candies does Daniel have ?

**Solution :**

No. of candies that Jose has = Double of what John has

= 12 + 12

= 24

So, Jose has 24 cookies.

**Problem 3 :**

Allen has 12 boxes of cookies. Lily has 4 more than the double of Allen has.How many boxes does Lily have ?

**Solution :**

No. of boxes that Lily has = 4 more than the double of what Allen has

= 12 + 12 + 4

= 28

So, Lily has 28 cookies.

**Problem 4 :**

Joshua traveled 8 miles and Peter traveled the double of Joshua. How many miles did Peter travel ?

**Solution :**

No. of miles that Peter traveled = Double of Joshua traveled

= 8 + 8

= 16

So, Peter traveled 16 miles.

**Problem 5 :**

Ethan has 4 pizzas boxes of cookies. Antony has 2 less than the double of what Ethan has.

**Solution :**

No. of pizzas = 2 less than the double of what Ethan has

= 4 + 4 - 2

= 6

So, Antony has 6 boxes of cookies.

**Problem 6 :**

Ryan traveled 8 miles and James traveled 3 miles more than the double of Ryan. How many miles did James travel ?

**Solution :**

No. of miles that James traveled = 3 miles more than the double of James

= 8 + 8 + 3

= 19

So, James traveled 19 miles.

**Problem 7 :**

Jonathan has 12 pencils. Samuel has 7 less than the double of Jonathan has. How many pencils does Samuel have ?

**Solution :**

No. of candies that Samuel has = Double of what Jonathan has

= 12 + 12 - 7

= 24 - 7

= 17

So, Samuel has has 17 pencils.

**Problem 8 :**

Dylan is 7 years old. Benjamin's age is 3 years more than the double of Dylan's age. Find the age of Benjamin.

**Solution :**

Age of Benjamin = 3 years more than the double of Dylan's age

= 7 + 7 + 3

= 17

So, Benjamin's age is 17 years.

**Problem 9 :**

Logan has $13. Brandon has $7 less than the double of Logan has. How much money does Brandon have ?

**Solution :**

Money that Brandon has = $7 less than the double of Logan has

= 13 + 13 - 7

= 26 - 7

= 19

So, Brandon has $19.

**Problem 10 :**

In a game Jackson has scored 15 points. Luke has scored 14 points less than the double of Jackson. Who is the winner ?

**Solution :**

Points scored by Jackson = 15 -----(1)

Points scored by Luke = 12 points less than the double of Jackson

= 15 + 15 - 14

= 30 - 14

= 16 -----(2)

Comparing (1) and (2), Luke has scored more points than Jackson.

So, Luke is the winner.
