Grade 4

Share the Headline Story with the class. Encourage students to find creative ways to answer the question.

Karly has 2 dozen eggs to give to her friends. She wanted to share them fairly, so she kept any eggs that were left over. Another time, she began with 23 eggs. How could she have shared the eggs in both cases?

When Karly had 2 dozen eggs, she could share them among 1, 2, 3, 4, 6, 8, 12, or 24 friends and have no leftovers. If Karly had 1 egg left over, she must have given 23 eggs to 1 friend or 1 egg to each of 23 friends. If Karly had 4 eggs left over, she must have given eggs to 2, 5, 10, or 20 friends. We can make a table of ways that Karly could have shared her two dozen eggs.

When Karly was sharing 23 eggs, she could do it without leftover eggs only if she gave all her eggs to 1 friend, or if she gave 1 egg to each of 23 friends. If she had 3 eggs left over, she must have given eggs to 1, 5, 10, or 20 friends. We can make a table of ways that Karly could have shared her 23 eggs, too.
