This is a bundle of materials I use for teaching regular AR preterite verb endings (including car, gar, zar verbs). Here's what's included:
ER / IR preterite note handout
ER / IR preterite board game
An Un Minuto Loco activity
ER / IR preterite battleship
A Ticket In on the verbs dar and ver
A Tira Seis game
All of these activities are also available in my Así se dice Level 1, Chapter 8 bundle.
