Students focus on developing strategies for solving the addition facts including reasoning strategies. Students build on their invented strategies to reason from facts that they know (e.g., make ten, use doubles). They describe strategies used to get to know and then solve a word problem. Students also start a year-long coin-collecting and exchanging activity. They also collect and analyze information about the birth months of their classmates.
