Easy trick to make sure women are called on enough.

Have a penny with you and have it heads for when you call on a female student in your class. Make it tails when you call on a male. If it’s staying tails for a while then it’s time to call on a women. Or you could just call on a female student after every time you call on a male student. You also do not have to wait for a student to raise their hand to call on them. Several strategies by others have been mentioned. I used to have my students write their names on one side of an index card and leave the other side blank. Then I would randomly select from the cards to call on students to share out. It also worked for dividing students into groups and randomly calling on a student to share out from a group.
