The Mathletics development team is pleased to announce the release of a brand new interactive. Walking back and forth, from Dr Marian Small, is the newest addition to Mathletics for Foundation level students and teachers.

Engaging in this task provides students with an opportunity to practice the counting sequence, observe the effect of moving forward and backward on a number line and explore, informally, the inverse relationship between addition and subtraction.

new interactive

Designed to develop conceptual understanding of addition and subtraction through problem-solving and reasoning, Walking back and forth includes an interactive, a student printable page, teacher notes and an assessment rubric.
