Summarize this article:

Once you think the child is ready to use the needles, cast on and knit a row of stitches for the child. Then, show the child how to insert the needle into the stitch to create a new knit stitch. Have the child watch you do this 5 to 7 more times. Go slowly and ensure that the child can see you insert the needle and loop the yarn around it. If the child wants to try knitting, hold the child's hands in yours so you're both holding the needles. Knit a few stitches together before letting the child hold the needles. Encourage the child as they try to insert the needle and loop the yarn. If the child doesn't want to try to knit without you holding the needles, don't force them to. You can always take a break and try again later. Once the child is successfully doing the knit stitch without any assistance, show them how to do the pearl stitch. Instead of inserting the needle inside and behind the existing stitch, show the child how the needle goes down and in front of the stitch. Slowly knit 5 to 7 purl stitches with the child watching you. If the child is having a hard time remembering how to handle the needle when making a knit stitch, sing this rhyme and show them the movements that go with it:  In through the front door (Insert the needle through the front of the stitch) Around the back (Loop the yarn around the needle) Out through the window (Use the needle to pull the loop through the stitch) And off jumps Jack (Slide the old stitch off of the needle).

Summary:
Use knitting needles to teach the child the knit stitch. Let the child try the knit stitch. Show the child how to knit the purl stitch. Sing a rhyme to help the child remember the stitches.
