## Abby and the number line

Students say some amazing things. Back Talk highlights the learning of one or two students and their approach to solving a math problem or prompt. Each article includes the prompt used to initiate the discussion, a portion of dialogue, student work samples (when applicable) and teacher insights into the mathematical thinking of the students. In this month's episode, a six-year-old rising first grader uses a computer simulation to understand addition and subtraction on the number line.

## Math by the Month: Speedy Gonzales

Do you remember clever, energetic Speedy Gonzales, “the fastest mouse in all Mexico,” one of the animated characters in the Warner Brothers Looney Tunes cartoon series? This month our “math by the month” activities, reminiscent of the spirited Speedy, will have your students calling ¡Ándale! ¡Ándale! ¡Arriba! ¡Arriba! (colloquial Spanish for “Come on! Hurry up!”) as they ask for more problem-solving scenarios based on this month's racing theme.
