Patterns in Mathematics-Number Patterns

This set of two interactive challenges from the Annenberg Teachers' Lab helps learners develop reasoning skills with number patterns by looking systematically at specific examples, and then by making predictions and generalizations. In "How Many Valentines", students try to figure out the number of valentines sent by an entire class. In "Mystery Operation", solvers try to determine what the computer's mystery operation is by entering a pair of numbers and studying the outputs. Background discussion, a rationale, grade-level information, connections to standards, and solvers' comments are included for each activity.
