If the Charlotte weather is keeping your kids inside, consider an obstacle course, like the one here in our gym.  You don't need fancy equipment to do it.  Obstacle courses are extremely fun for kids and they increase skills in: gross motor coordination, sensory processing, visual motor, sequencing, timing and even visual perceptual skills.   A three year old can handle about 3 parts, while older kids (3td grade) should be able to complete 5-6 part obstacle courses.  

On mine, I incorporated visual discrimination and matching with the white letters (face down) around the swing.  The child had to match letters (visual discrim) of her last name while laying on the swing on her belly (core strength).  She picked up the letter and propelled the swing with her arms (upper body strength) to match the letters.  

If you have some cushions, pillows, and old comforters, then consider making a big crash area in your obstacle course.  Kids love it and it is a great way to get some proprioception (think calming) on an indoor day. 

Yesterday, our Mini Charmer's class enjoyed our rice tubs that had letter stickers "hiding" in them.  The kids were instructed to find and then match letters (building a letter team) on the wall.  The boys liked counting and keeping current stats.    The "W" team ended up winning with the most! This activity helps with letter recognition (visual discrimination), sensory processing, pre-handwriting, fine motor dexterity and team work. 

On the other center, kids were instructed to pick out a stencil and use 2-3 marker colors to create the design on a coffee filter.  Once done, we put the filter over a white piece of construction paper.  The kids then used a spray bottle to squirt about 5 squirts on the design.  The colors bleed together to make a cool design.  Kids will lift the coffee filters this coming week to see what kind of design it made on the construction paper. This activity helps with pencil grasp, non-dominant stabilization, truck stability, finger/hand strength, and sensory exploration.  

Our occupational therapists enjoy working with kids and making therapy fun.  if your child is learning to recognize letters, up the challenge by offering letters turned this way and that in a bowl of non-letters.  This challenge in picture actually uses water beads, which is a sensory experience in itself.  The specific goal here is to increase visual discrimination (meaning, can the child recognize the upper case letter if it is turned a different way?).   Once they find the letter, have them place on a line and see if they can orient in the right direction and perhaps spell out their name or another word.  Have fun!
