  18. Connections to Higher Math

  19. Counting Additive Multiplicative Proportional Reasoning Algebraic Reasoning

  20. Math is Figure-out-able • Look to most efficient strategies • Teachers build own numeracy • It’s about relationships: • Among numbers to solve problems • Between teachers and students to build young mathematicians
