Students are able to “stick with” problems and will try multiple methods to reach a solution.

Students understand that written numerals represent real world objects and quantities.

Students are able to explain their own mathematical ideas and strategies and they respond to the thinking of others.

Students use pictures, objects, numbers, and/or words to express their mathematical thinking and reasoning.

Students select the appropriate tools and resources to solve a problem.

Students use detailed and accurate mathematical vocabulary to communicate mathematical understandings.

Students notice attributes and structures in mathematics such as: sorts shapes by the number of sides or recognizes that 4+6=10 and 6+4=10.

Students identify patterns, make predictions and use repetitive actions that support computation: 12 + 5 is the same as 10 + 2 + 5.
