# Snowy Subtractions

Description

This colourful game provides opportunities for students to practice the Jump or Inverse Strategy.

This resource includes a reproducible recording sheet, with number lines, which not only assist the students in finding the answer, but it makes a great formative assessment tool.

It was designed for the Year 2 Mental Subtraction Strategies Unit, but could be used in the Year 1, for extension or Year 3, for consolidation.

Fast finisher, numeracy rotations, laminate for multiple usage.

Suitable for
• Fast Finishers
• Relief Teachers
• Parents
Lesson Structure
• Rotations / Group Work
