First time hs-ing..but what do I do with 4 yr old??

To be honest, that idea was taken from my second son's kindie teacher last year, he came home loving it...and sure enough, my little one lovs it too. He saved it in his room until I finally sneaked in and threw it away...the ants love that sort of artwork too!! lol

 

Give your 8 year old an activity to do with the 4 year old and give them a timer, set the timer for 20 minutes or how ever long you think they have the concentration. Then the 8 year old has to "teach" the 4 year old while you get one-on-one with the 6 year old.

It may work too for the 6 year old to "teach" the 4 year old for 15-20 minutes while you get quality time with the 8 year old.

But in the main try and do activities that all three can work on together. Don't think that the older two are in school and the 4 year old isn't and is in the way. Teach all three together. It's also helps to teach the 8 year old to work independently.
