Using arrays to model division and find equal groups

By CCSS on Apr 24, 2017

This lesson is designed to teach students to use arrays to model division and find equal groups.  There are a number of barriers to this for students who are blind or visually impaired, including some of the following:

  • math being such a visual subject
  • accessibility of materials
  • materials needing to be adapted
  • many examples in student texts and workbooks are meant to be visual and braille versions can be (and have been) confusing
  • student is provided a copy of the notes, but what is written on the board isn’t always on the notes
  • knowledge of place value
  • solid understanding of multiplication facts 0-10
  • understand and be able to use the distributive property
  • understand and be able to use a multiplication table
  • recognize patterns on a multiplication table and in multiplication facts
  • describe patterns
  • creating equal groups

Materials

Procedure

Access to this lesson can be provided using some of the following strategies:

  1. Use assorted manipulatives instead of making pencil drawings
  2. Put manipulatives on a Grid Board
  3. Use a MathWindow
  4. Use adapted multiplication table
  5. Use a Draftsman
  6. Use a hundreds chart
  7. Dycem to keep materials from slipping
  8. Work trays to keep track of materials

Variations

Functional skills can be incorporated into this lesson, including:

  • working together
  • problem solving
  • reading/following directions
  • listening skills
  • cooperation
  • asking for help when needed →to clarify directions, when task is unclear, when there is misunderstanding
