Have you done any further research with your hinged number line? <br />You might be interested in a Stanford study that was done in 2015 in neuroscience regarding understanding negative numbers and how the brain uses symmetry to understand abstract concepts. https://news.stanford.edu/2015/07/06/symmetry-math-schwartz-070615/ <br />Thanks for sharing this and your thesis!Lindahttps://www.blogger.com/profile/07043369911584866519noreply@blogger.comtag:blogger.com,1999:blog-969821499728229660.post-88438730449533078472017-10-01T14:52:16.587-04:002017-10-01T14:52:16.587-04:00There are directions on the back for same-sign pro...There are directions on the back for same-sign problems. I explain it to my students this way... when we were kids and were adding 8 + 8, we didn't think about signs because they were the same. Now with -8 + -8 the signs are still the same, so we add and keep the sign like we did when we were younger.
