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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("teaching in mathematical") OR ((("teaching to mathematica") OR ("teaching and mathematica"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"teaching in mathematical\") OR (((\"teaching to mathematica\") OR (\"teaching and mathematica\"))))*".
• Removing quotes may allow a broader search: (( teaching in mathematical ) OR ((( teaching to mathematica ) OR ( teaching and mathematica ))))*.
