This packet includes Memory (Concentration) cards for 47 of the most common irregulars (6 game sets of 16 cards each—‘to be’ gets two), along with instructions for preparing and playing memory games and a couple of other useful games to practice irregular past tense verbs.
These games make great change-of-pace or end-of-class activities. Most are quite fast, once the materials have been prepared, and simple to learn.
With six sets of cards, you can have the whole class play a memory game (make an extra few sets for a large class), then have them trade sets for a second game or another day.
Memory also makes a great review if some students finish their work early (or even for one student who needs extra practice. It can be played by one player or up to four.)
If you would like other irregular past tense games in addition to memory card games, consider getting "Games to Practice Irregular Past Tense Verbs"
($4.75) instead. It includes all these memory cards and game ideas, with two past tense sentence scrambles and a team gap-fill race as well.
