Amina is a little girl who lives in a city called Minneapolis with her mom, dad, and baby brother, Alfie. Amina is a very happy girl. She loves her family and mathematics. But recently things have changed at school. Some of her schoolmates have started to say and do mean things to Amina and some of her friends because they are "different". It has been making Amina very sad. Luckily, Amina has a mom who reminds her that she and her friends are wonderful, just as they are.
