If you already have the title and abstract for your article, you can use the following tools from Elsevier and Springer to help you pick a right journal among those that belong to the respective publisher
http://journalfinder.elsevier.com
http://journalsuggester.springer.com
The output of these tools shows inter alia average article processing times and impact factors of the journals and, if I recall correctly, also publication fees and open access fees. In many journals you can publish free of charge if you do NOT make your article open access (i.e. it is available only to journal subscribers), but this should be checked for each journal separately.
Once you make a short list of potentially suitable journals, you can check whether they are covered by Scopus here
You may also like to have a look at the ranking of the journals in mathematics education before you choose the one for your submission. This list also complements the one from Scopus in Abdelrahman’s answer.
Le recomiendo la revista de MEXICO REDIE y una que publica el CLAME(Consejo Latinoamericano de matematica Educativa) en el evento RELME Reunion Latinoamericana de Investigacion Matematica, cordial saludo Lourdes
