Nine-year-old children are curious about the world, and are full of questions about how things work and why things are the way they are. They may ask about everything from why there is war to what we can do to help better the environment to why the sky is blue. They will be able to think critically, and will express their own opinions about things.

This is a great time to introduce a child to research tools such as kid-friendly websites and news magazines.

The library is also an excellent place to take your child to show him how to find information about things he is interested in.

Nine-year-olds also have longer attention spans. They will be able to focus on something for as much as an hour or more. At this age, children will develop interests and cultivate them with passion, and will love doing research to find out all about their favorite topic. Whether it’s reading suspenseful books, playing baseball, or finding out all they can about the world of Star Wars, your child will pursue his interests with admirable diligence and focus.

At school, 9-year-old children will generally work well in groups and will cooperate to work on a project or activity. They will want to work on a subject, topic, or particular part of the curriculum until they become skilled and master it. Parents can offer support and guidance by encouraging kids to keep going when they become frustrated.

Reading and Writing
Nine-year-old children are able to write and read skillfully, and will be able to express themselves using complex and sophisticated vocabulary and ideas. You can expect your 9-year-old child to be able to read different types of fictional and non-fictional works, including biographies, poems, historical fiction, suspenseful series, and more.

In fourth grade, your child may also be expected to produce various types of writing including book reports, essays, fiction, and historical fiction. Nine-year-olds will be able to use research material from the library and the internet to gather information for reports on various subjects including historical events and figures.

Numbers and Math
Math will become much more complicated in fourth grade. Nine-year-old children will tackle multiplication and division of multiple digits, learn fractions and geometry, and may begin algebra. They will learn how to make graphs and charts using data, and will work on word problems that require analytical and logical thinking.

By the end of fourth grade, nine-year-old children will know how to add and subtract fractions, know about different angles and how to measure them, and be able to collect, organize and share data in reports and presentations.
