Mathematical Processes

Number and Algebra

Problem Solving:  Use equipment appropriately when exploring  mathematical ideas. Logic and Reasoning:  Classify objects. Communicating Mathematical Ideas:  Devise and follow a set of instructions to carry out a  mathematical activity.  Record and talk about the results of mathematical  exploration.

Make up, tell, and record number stories, up to 9, about given  objects and sequence pictures. Form a set of up to 20 objects. Read and write any two­digit whole number. Rote count to at least 50. Make sensible estimates and check the reasonableness of answers. Model and explain addition calculations with a sum of up to 20. Using up to 20 objects, model and explain subtraction calculations.
