Instructional Ideas

• Create laminated sets of these templates or place them in plastic sheet protectors, allowing children to use dry erase makers while practicing two-digit addition
• This template can also be used when teaching about two-digit subtraction without borrowing
• Use this template as an instructional tool, projecting it for the whole class to see as you demonstrate how to perform two-digit addition

Classroom Considerations

• A plus (or minus) sign is not included on the template, but can be written in by hand before making copies

Pros

• Template is large, making it easy for young children to fill in the necessary information
• Provides space for recording the vertical addition problem as well as room to record the value of the tens and ones place in each number

Cons

• Written instructions are not included on the template itself, requiring the teacher to provide a clear demonstration of how it is used
