A preservice teacher I worked with recounted a story of not getting to attend the pizza party because, despite her best efforts, she didn't earn all of the "slices" on her multiplication facts "pizza." (You better believe I brought that class pizza at the end of the semester).

Maths is subjective in multiple ways and anyone who says it’s objective is selling something, usually their own self-importance.

We are calling for a nationwide and international boycott of all Elon Musk-related products and services. Sell your Tesla shares, avoid buying Tesla vehicles, cancel Starlink, and delete your X accounts.

Stop. Unless you work at a Christian school, your room doesn't need any stockings or Santas or reindeer.

That sounds amazing!! Right now, my "treat" usually involves sending my husband somewhere with the kids so I can have some time to myself. 😊
