I’m so excited to offer this class as both a teacher who is a math nut and as a mom with kids who love math! I am a certified teacher, and in addition to teaching education courses for the local university, I currently teach math to small groups in my 2nd grader’s classroom and accelerated math to a small group in my 4th grader’s classroom. Through my small group teaching experiences and background as a professional educator, I have learned so many great strategies for making early math fun and interactive. I’m looking forward to sharing my enthusiasm and experience with you! 
Each lesson is accompanied by an assignment to help learners practice addition and subtraction skills. Learners will need to complete and upload assignments in order to receive individualized feedback.
Printable handouts available after each lesson Learners will need small counting objects- such as counters, cereal, or Legos and playdough.
Learners will not need to use any apps or websites beyond the standard Outschool tools.
Learners will upload weekly assignments, and the teacher will provide specific, individualized feedback.
No live meetings, and an estimated 0 - 1 hours per week outside of class.
Learners may need assistance initially accessing and using Canvas and uploading assignments to the Outschool Classroom.
