Show children a large image of a J. Draw it on a chalkboard or cut it out of paper. Ask children to repeat after you as you say the name of the letter and the sound that it makes. You may also list some words that begin with J so children can hear the sound of the letter.
Ask children to hunt for the letter J. Pass out newspapers or magazines and ask children to cut out every J they find.
Help each child cut out a block letter J out of paper and glue their magazine letters onto it. These Js can be hung on the classroom walls as decoration and further reinforcement of the lesson.
Create tracing sheets with the letter J. Write the letter all over the paper using dashed lines. Use half lowercase and half uppercase letters.
Pass out tracing sheets. Ask children to trace over the letters using crayons or pencils.
Give children sheets of plain lined paper. Ask them to fill a few lines on their papers with letter J's. You may hang up a letter J for reference. Writing the letter without the help of a traced outline gives children practice forming it themselves.
Lead the class in jumping jacks or ask them to pretend to be jumping beans, bouncing around the classroom. Not only will children learn some J-related activities, but they'll get exercise.
Make art projects out of words that begin with J. Pass out paper and art supplies and ask children to incorporate several items. They might draw a classmate named Joey eating a jelly sandwich in the jungle, or draw unconnected images of J words.
