The above image is of a concept map I created in my Investigating Mathematics and Learning class about subtraction. I used the bubbl.us website to create the concept map which includes things like terminology and manipulatives used during subtraction. If you click on the image, it will link you to a PDF version of the concept map.

The following standards were met when creating this concept map:

ISTE Standards

2. Design and develop digital age
learning experiences and assessments

d. Provide students with multiple and varied
formative and summative assessments aligned
with content and technology standards, and use
resulting data to inform learning and teaching

3. Model digital age work and learning

a. Demonstrate fluency in technology systems
and the transfer of current knowledge to new
technologies and situations
