I try to make my lessons fun. I do themes/find a way to work in subjects she's interested in. This year it's fables, fairy tales and tall tales and I am ridiculously excited.
I've managed to find most of my curriculum and now I will go and find music/songs/visual aids and crafts that match the lesson. I also read picture books on the subject so she's more familiar with the subject from another person's narrative, just Incase mom got it wrong. (I actually check everything numerous times, I just panic lol).
For example, when we read the Little Red Hen, we'll probably bake some bread with our lesson. It's teaching her the fable, math, cooperation, following directions and basic life skills.
When we're doing the Emperor's New Clothes we'll be making these little dolls with clothes (fabric glue and cloth). Then I'll tie in to my "fashion" from around the world (world culture introduction, I have a little diva, she didn't get it from me but she's fancy). That'll link to geography and the 7 continents.
I also do a lot of "body breaks".
We dance. Air guitars, chicken dances, you name it. It's good for little ones to move (we both have ADHD) and redirect their focus. If she gets stuck or doesn't understand something/frustrated we do a body break. If we've been working hard for a while, body break.
"Shake the Sillies Out" is a huge hit for little ones. On YouTube, you can find hundreds of free songs people have created to help. Nursery rhymes, days of the week, season, months, etc. Lots of singing and playing helps. At 3, they won't have the muscles to really write so color, use sugar in a tray to make letter shapes. Colors, numbers, patterns and blocks are great for little ones.
Have fun. Make it fun.
Also, my kid may be weird but she'll look at me blankly until April, right when I think she's learned absolutely nothing and I'm a complete failure. Then everything comes together beautifully so there's a lot of questioning yourself if your little one is like mine, but they absorb and they're smart.
You've got this. I personally enjoy it and she does too. She's a year ahead in math and we only do 3 days a week, 3 hrs or so a day. She actually asks to do school. Sometimes, for fun, we'll do "night" school, because we can. (Apparently glow sticks, low lighting and the secretive conditions of darkness make her unbelievably giddy. Kids are a trip).
