The "Grade 1 Subtraction" activity packet is designed to meet the curriculum expectations outlined in the Ontario Mathematics curriculum. This packet introduces students to single/double digit subtraction using a variety of activities and lessons. In this packet students are asked to subtract numbers within 20 (e.g., 12 - 6 and 6 - 5).
Section 1: Templates
This section includes several templates that can be used for students who are adding with manipulatives. The templates included are a hundreds chart, a fives frame, and a tens frame.
Section 2: Lessons and Activities
This section contains all lessons and relevant activity worksheets/activity suggestions. There are 5 lessons included in this packet. Each lesson includes a lesson introduction, a core learning activity and a lesson consolidation. Each lesson also has one or two follow-up activities that students complete to practice the skills discussed in the lesson introduction. You will need manipulatives for some of the lessons (i.e., snap cubes).
Section 3: Additional Activities
The additional activities section includes several additional activity worksheets that can be used by students to practice subtraction skills. These activities can be used for early finishers or if students need more reinforcement with subtraction at the Grade 1 level.
Section 4: Answer Keys
This section includes answer keys for all activities in the order that the activity worksheets are presented in the activity packet.
This packet would also be great for those students in Grade 2 who might need some reinforcement/review for subtraction skills developed in Grade 1. If you have any questions, please feel free to let me know.
