Any shoveling tips for a newbie?

I moved here from a warm climate and have never shoveled before. My partner that was being and raised here told me he would shovel or at least show me how but of course hasn't. I have a two year old and a small infant and climbing down our stairs and sidewalk is terrible. my two year old and myself both fell this morning and I imagine anyone trying to walk on our sidewalk has probably done the same.

I'm done waiting for my partner to get around to it but before I make myself look like a fool anyone have any tips? We have big sturdy plastic shovel and I finally found my mittens.
