My wife is a kindergarten teacher and absolutely loves TeacherPayTeachers. For younger kids, the quality of stuff she finds is much higher than what I guess you find for older kids&#x27; math. She uses is not because she can&#x27;t make materials, but because the ~$1 it costs to purchase material cuts about an hour or two out of her several hours of planning and creating materials a night that she does between 5-10 on weeknights.
