Perhaps you should try some spelling variations:
"teaching and mathematica" » "teaching in mathematics", "teaching con mathematica", "teaching en matematica", "teaching of mathematica"
"teaching in mathematica" » "teaching in mathematical", "teaching in mathematics", "teaching con mathematica", "teaching of mathematica"
"teaching las matematicas" » "teaching of matematicas", "teaching for matematicas", "teaching the matematicas"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"teaching in mathematica\") OR (\"teaching and mathematica\"))) OR (\"teaching las matematicas\"))~".
• Removing quotes may allow a broader search: (((( teaching in mathematica ) OR ( teaching and mathematica ))) OR ( teaching las matematicas ))~.
• Adding a wildcard symbol may retrieve word variants: (((("teaching in mathematica") OR ("teaching and mathematica"))) OR ("teaching las matematicas"))*.
