A nine-year-old's craft projects should keep the general goals of safety in mind but allow for greater flexibility on the part of the child. Close supervision should not be the cornerstone of the project. Aside from creativity, self-expression and skill development should be the objective. Having fun is always great, but crafts for children at this age should aim to have an educational aspect.
Anything that involves numerical values can work for math studies. Addition and subtraction are basic skills, but multiplication and division have been introduced around the age of nine. Crafts using simple calculations are fun and can reinforce these principles. Create any type of chart using poster board, foam core or foam objects. Make a chore chart; parents and/or teachers can list chores the child is expected to do each day. The child can decorate the chart with stickers, glitter and drawings and use stickers to indicate a completed chore. Leave an area so that the child can calculate allowances or payment using math skills. At the end of the week, the child can count the stickers and earn a reward.
Science can be endless. The uses of magnets are popular at this juncture Studies of nature, specifically animal species are popular study units. Have children assemble animal models. Most craft stores sell a variety of wooden or foam kits requiring assembly of animals, insects and reptiles. Kits using basic chemicals such as volcano "eruptions" are also available. With these types of projects, the adult and child can read the instructions together but the majority of the project can be completed by the child while the adult looks supervises the use of items such as scissors or messy materials.
By age nine, reading comprehension takes a valuable step into the student's life. A 2004 by the University of Tennessee found that oral reading allowed for greater comprehension in children of this age group. After a book is read out loud, comprehension can be tested by allowing the children to create a diorama. Use shoe boxes, clay and other materials to create a scene, a conclusion or a depiction of events from a story. Creating a 3D project can help a child convey his understanding of a story.
