The first step to teaching the above is strengthening the small muscles in the hands and wrists that are used in handwriting. This process is often referred to as building fine motor skills. You can encourage fine motor development by having your child use art supplies like crayons, paints, markers, glue and scissors.
Homeschool worksheets are a vital part of the student's homeschool experience. They allow the child to test his or her knowledge, and they offer them a practical application for their learning.
Lacing activities, stringing beads and cheerios, playing with playdoh, scooping sand or rice, and activities like pouring and stirring are also great fine motor activities.
Since 3rd grade math relies on the concepts that were learned during kindergarten, first and second grades, don't be afraid to start your child at a lower level.
