Math in Our World: Two Little Libraries

Two little libraries. The one on the left has 2 blue books and 5 orange books inside. The one on the right has 3 blue books inside.

There are two little libraries in my neighborhood. My neighbors use them to share books. Sometimes I donate books to the little libraries. Sometimes I take books home to read.

I love to help keep the little libraries clean and organized.

  1. Use pictures, models, or numbers to show what you know about the books.
  2. What do you notice? What do you wonder?
  3. What math questions can you ask about the little libraries? Answer all the questions you can!
  • Use blue and orange blocks or other small objects to represent the books.
  • Count on to find how many books there are in all.
  • Use what you know about doubles to put the blocks into equal groups.
  • Show your work to someone. Use numbers and math words to explain your thinking. Did they understand?
  • Ask whether they have any other questions you can answer!

Find some books at home or draw some. Put the books into two or more groups. Make up your own story problem!
