Chris the Coyote sits by a cozy campfire and opens his satchel.
"Let me tell you about the night of the big camping trip," he begins.
"Twenty-nine friends came, and each tent holds only 4."
"Oliver said 29 ÷ 4 = 7 R 1. Then he frowned."
"Seven tents leave one friend outside! So they set up 8 tents."
"Next, Bennie packed 50 apples into bags of 6 for breakfast."
"He filled 8 bags, and 2 apples rolled into his pocket for later."
"The remainder means something different in every story," Chris says.
Read the question to decide what to do with a remainder.
Tents: 29 ÷ 4 = 7 R 1. Everyone needs a spot, so round up to 8 tents.
Bags: 50 ÷ 6 = 8 R 2. Only full bags count, so there are 8 bags.
Left over: there are 2 apples that are not in a bag.
Some problems take two steps. A letter can stand for the unknown.
Oliver has 3 boxes of 24 books, plus 15 more books.
n = 3 × 24 + 15. First 3 × 24 = 72. Then 72 + 15 = 87.
Estimate to check: 3 × 20 + 20 is 80, close to 87.

What a trip! Tomorrow Freddy has a review game.
