Parenting advice for a 2 year old

Im writing this because I need to opinions on the situation I’m having with daycare now my sons been in a couple of in-home daycare‘s of people we trusted and never really had a problem with it. This August he started a daycare at a Christian school and I’ve been getting letters of concerns with my child hitting and pushing other kids. My child’s a only child at home he doesn’t really have that behavior at home he does have his tantrums but he is 2 and 100% a wild Goofy boy. The superintendent and Teacher wants to meet with me and my husband to discuss his behavior but I don’t really know what to do I mean he’s been going there for three months and every time I drop him off he is screaming he already knows where he’s going when we pull into the place I mean I just don’t understand how he doesn’t like it and teacher make me feel like my child is doing something bad whenever I’ve asked the teacher multiplications if he was the only one do it and she said no. I guess what I’m asking for is some perspective if anyone’s gonna do this with your two-year-old at daycare what you guys did and how you guys handle
