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.

Solve simple addition problems to 20 by joining both sets and counting all the objects
2 + 3 = 5, 1 + 4 = 5, 3 + 4 = 7, 5 + 5 = 10, 2 + 5 = 7, 6 + 3 = 9, 8 + 5 = 13, 9 + 6 = 15
