Curriculum Context:
   1st Grade Classroom
    (lessons and activities
    are easily adjustable for
    wide range of learning
    levels of children)

   Hartford Public

   Time Frame: 2 hours a
    day for about 6 days.
Objectives:
   Work individually, with peers and with more mature
    learners.

   Students will be able to apply each area of math to real
    life situations.

   Blooms Taxonomy Students will spend time on the
    understanding (describe, identify), application (interpret,
    solve, write), and synthesis (formulate, organize, write)
    stage.
Objectives: (from CT Framework)

  – Students will be able to “use models and pictures to
    demonstrate understanding of equivalent forms of
    numbers .”

  – “Students will add, subtract with whole numbers,
    estimation and develop strategies for selecting the
    appropriate computational and operational methods for
    solving problems.”

  – “Students will use #’s to count, compare, order and use
    a variety of numerical representations to present,
    interpret, communicate and connect various kinds of
    numerical information.”
Addition (Day 1&2):

   Around the World game
          Students compete with one another to see who can correctly
           answer the problem on the flash card
Estimation (Day 6):
   Give brief lesson on estimation:
               Define estimation
               Show examples
