Understanding months isn't very complicated. In here i will first explain what months are .
Obviously the English months began with January end with December. I'm
going to write the month out and English. Then translate to Spanish.
Ex. fecha de hoy es trienta de octubre dos mill diez . - Today is october 30th, 2010.
The way I would teach time in Spanish is to show my students an example of the clock in English and show them the same clock only in Spanish then I would make them solve the rest of the problem with the information of Spanish numbers that they know. I also would use hints of what stay the same and what changes.
1:00= es la una
1:10pm= Es la una de la tarde
1:10am= Es la una y diez de la mañana
2-12= son las dos-doce
see I leave a hint to leave the"es la"(only use this for one) by bolding it and I also bold "de la""son las"(use for 2-12) and "y ___ de la". I would also put pictures and explain more that once.
