    learn vocabulary and math facts/solve math problems on weekly math newsletter
    Students will be tested most Friday on the information presented on the summary newsletter
    required 15 to 30 minutes of at home reading from their IRLA book

    Why I Don’t Give a lot of  Homework

    While students are asked to read nightly, to study the math facts for addition, subtraction, multiplication, and division, close read weekly science or social studies news, and review weekly math summary, I do not assign extra ‘homework’. (Reading is the BEST way to learn and studying math facts is so important~ it is the foundation for ALL math)

     

    So why don’t I give a lot of  ‘homework’?

    Because school is for students, and home is for children. Children are still learners at home.  A learner does not need time-wasting, rote, and repetitive tasks. Children should not be overloaded with demands from teachers after working diligently in school all day.  Children should play at home.  They should have the time to participate in activities that exercise the body as well as the mind.  The learner should be encouraged to read to better understand the world around them and develop their overall intelligence.  Children should have the time to interact with families in a developmental ‘fun’ way instead of time wasted ‘being stressed (parents and child) completing homework’.  Children should have the time to learn through everyday household routines.  Above all, children should have the time to value their relationships and time to learn from those around them.  This is the most important ‘homework’ of all.

     

    So, I don’t give a lot of homework.  I would rather see my students be children who are still learners when the dismissal bell rings.
