What does crossing the midline mean?


What is crossing the midline?


The ability to cross midline reflects the degree of bilateral integration development.  Mature midline crossing patterns should be demonstrated by ages 4 – 6 years.


How do I know if my child is having problems with this?


Well there are a few observations you might frequently see such as:


If asked to draw a line across the paper your child will turn the paper so that there is no need to cross the midline.


Your child will begin writing with the dominant hand and upon reaching the centre of the body they will change the pencil to the other hand.


Your child may have difficulty visually scanning from the dominant to the non-dominant side - this may be evident when reading or copying from the blackboard.


What can I do to improve this skill?


Here are a few fun activities to try at home!


Place bracelets on each arm and encourage the child to remove them with the opposite hand


Wrap one arm loosely in toilet paper and encourage the child to remove the paper with the opposite hand


Place finger puppets on one hand so they can be removed with the opposite hand


When passing objects hold them initially at a distance so as to encourage reaching past the body’s midline to grasp them


Blue-tac pictures to the wall that have to be retrieved by reaching for them in different directions


Walk sideways along a line/rope/balance beam - crossing legs over each other


Cut out right and left feet shapes - place these to the child must cross his legs when walking on the shapes


Playing percussion instruments / cymbols / triangle / clapping hands etc


Bi-lateral activities: threading beads / folding paper / sewing cards / small wind-up toys / cutting and pasting


Side sitting on floor when doing fine motor activities so that one hand has to cross the body


Banging blocks together in midline


Draw large circles / horizontal figure 8 on the chalkboard without lifting the chalk and keeping the elbows as straight as possible


Sitting on the floor, draw a circle around you with chalk not changing hands and without turning your whole body around


Nesting cups – pulling apart and putting together


Streamer circles and other patterns (using a ruler or piece of wood and fix a long plastic streamer to it eg. can cut up garbage bags for this) - hold with both hands or one in each hand


Removing lids from containers


Construction games.


Dress-up games.


Simon says e.g. cross you legs / touch your left ear with your right hand / swing your arms side to side across the body.


Passing beanbags from one hand toe the other across the body - try to do this blindfolded


Planting seeds in the garden


Reach across the body - hitting a suspended ball with bat or hand eg. tennis ball in the toe of a stocking hung from the clothesline


Use cardboard tube as a bat, held with 2 hands, to hit thrown objects to either side of the body


Enjoy the activities!
