Previously Published Data 

1.) Students will solve mathematics problems explaining differences and similarities in their Mathematics Journals.  

2.) Students will keep a section labeled "Connections" in their Mathematics Journals for recording the connections they see in their studies. For example: 

  • Horses + ears is like tricycles + wheels because they both have a special relationship. Each horse has 2 ears and each tricycle has 3 wheels.
  • Expanded notation is like building with blocks because you just multiply the number in that place with the block number. 800 is 8 x 100 
    • Previously Published Data 

    1.) Given a word problem, students will show two ways to solve the problem, explaining their differences and similarities. They may use pictures, words, and numbers.
