Keep it short and simple

Very often parents are overly eager to have their children write one more work or even another
sentence. Try to resist the temptation of over achieving.

  • Keep lesson time within 10 to 15 minutes
  • Have you child practice writing for approximate 5 minutes in total

You can increase the amount of pencil time gradually, by adding drawing and coloring activities, so that your child stays interests and does not become overly tired.

Practice Makes Perfect
Practice regularly - daily if possible, or at least three times a week. Again, keep the lessons short and enjoyable by incorporating pre-writing skill worksheets or coloring and drawing instructions to your pre-writing practice.

  Progression Tip: As your pre-schooler continues to develop his writing skills, the movements he uses to write will come more from the wrist than from the entire arm.  

Rest & Relax
If you notice your child getting tired after 5 to 10 minutes, help him relax by having him shake his hands, make drawings in the air, or roll a piece of Modello inside his hands.

  Note: If your child is switching hands at this stage, he hadn't figured which is his master hand. This is not unusual, do not panic, and also do not make that decision for your child. Instead, encourage him to explore with both hands using some of the fun activities. Eventually he will decide on one hand.
