1.M.1.6. Comprehension: Students are able to compare and order concrete objects by temperature and capacity.

SD.1.N. Number Sense: Students will develop and use number sense to investigate the characteristics of numbers in a variety of forms and modes of operation.

1.N.1. Analyze the structural characteristics of the real number system and its various subsystems. Analyze the concept of value, magnitude, and relative magnitude of real numbers.

1.N.1.1. Comprehension: Students are able to read, write, count, and order numerals to 50.

1.N.1.1.a. Say the forward and backward number word sequences in the range 0-50.
