For October I am recommending two books written by the same author, Barbara Park.
First, Junie B. Jones Has a Monster Under her Bed. This book is perfect for this spooky time of year. It's main character, Junie B., is a kindergartner, and always getting into some crazy situation which she seems to survive using the most unique strategies.
Second, Junie B. Jones, First Grader, Boo and I Mean It! This book is one in the first grader series.
Both series has many titles and they will make readers, both young and old, giggle with delight!
They are published by Scholastic, New York and can be found in the beginning reader's section of your local book store as well as your public library.
Craft - Fabulous Foam
Look for foam sheets, foam shapes, or foam craft sticks in your local craft shop. They are cheap and fabulous for children to work with. You can easily cut out shapes to make holiday pictures (use can use children's beginning coloring books for patterns), and it works well with most types of glue. Because they are light, they also make wonderful garland decorations, ornaments, or mobiles. They are ideal for adding to cards or scrapbook pages too. Use them for making place cards for your Halloween or Thanksgiving table. Here is a cute fast project I made as a window decoration using foam craft sticks and some construction paper.
