MODIFICATIONS   

Instructional

The teacher uses a sorting activity on the SMART board.  The worksheets contain word problems, math sentences, and pictures and fill in the blanks.

Students compare between a doubles fact and a non-doubles fact. Students can apply their skills in various ways/strategies

Students see the difference between a doubles fact and a non doubles fact. Students learn through multiple intelligences.
