This activity focuses on school supply vocabulary and can be used with any textbook - Realidades, Expresate, etc.
The students will look at an infographic found here (http://leonardo1452.com/wp-content/uploads/2011/08/Regreso-a-clases1.png) and using basic math skills and some internet searching, will compare and contrast the cost of going back to school in the United States versus going back to school in Mexico. This is an excellent activity to use to get students thinking and opens the floor up for great discussion. It also has some new vocabulary for school supplies and clothing that the kids had fun with.
I left this with a substitute and the kids did well on it so it makes a great sub plan. They used their phones to complete the activity and I wrote the exchange rate on the board so they just had to do some basic math.
