This kit contains almost everything you need to help your students learn, practice, and demonstrate their understanding of addition and subtraction concepts. Included in this download are 90+ pages of activities, worksheets, QR Codes, games, and mini-posters.
The topics covered in this kit (each with posters and activities) are:
- introduction to addition, subtraction, and equations
- friendly numbers and fact families
- properties of addition:
- commutative, associative, identity
- solving addition problems (carrying and non-carrying)
- solving subtraction problems borrowing and non-borrowing
In my own classroom, I am working on motivating my students to be self-directed learners, so I designed this kit as a way to allow them to move at their own pace through addition and subtraction concepts. To this end, I have a plastic container that I labeled “Addition and Subtraction” and have laminated copies of the mini-posters and QR codes, folders with the activities photocopied inside, and self-directed learning rubrics for each student that connect to my school’s measurement topics for addition and subtraction. My students are thus able to work at their own pace through these lessons and also to track their own progress.
Here's a more detailed look at the mini-posters and activities included in this kit.
