This video shows the benefits of working in a vertical surface for fine motor grasp patterns.
Some students find it easier to engage in writing and math activities when the paper is slightly elevated or on a slant. This helps with both their eye-hand coordination as well as their wrist position. To make a slant board at home, find a large binder (at least 2-3 inches) and use a large butterfly office clip to secure the paper.
Use a consistent schedule as much as possible, with clear expectations and timeframes.
Use sensory motor breaks to prepare the body/mind for focused work or as a break when engaged in a challenging/frustrating task.
Find natural ways to promote skills/development (it might not turn out exactly the way you want it), but let your child help you fold towels, bake cookies, sweep the floor, carry the trash out and other life skill based activities.
Keep in mind the goal of the task at hand. If you are working on learning proper letter formation, it might not be the time to worry about how well your child is placing that letter on the baseline. As they become more successful with one component of a task, then add in another element.
Set aside a time for electronics that will not interfere with school and therapeutic work.
If your child is struggling with an activity, consider how you can make it easier for them. If they are successful they may be more inclined to continue working on the task or engage in it again at a later time. Tasks can be made simpler by: having half of the task completed and then let your child finish the rest, take turns completing a part of the task or adapt the task to meet their skill level. And there is also the option of taking a break and coming back to it later.
Give plenty of praise and encouragement, even when it is not completely correct. Point out what they are doing well and their perseverance with a task.
Have fun with it!
