This is a great and easy activity to get kids conjugating (I do it with speaking, but it could be easily done with writing as well).
The document is 3 pages. Print them and copy them onto card stock. Laminate if you wish. Each card has a sentence in English and the translation in French, using either VOIR or RECEVOIR.
Give all kids a card. The idea is for them to circulate around the room, giving different partners a sentence in English. The partner has to translate it back orally (or written, if you prefer). The first person tells them if they're right or wrong, and then they trade cards and continue on to the next person.
This activity can last 5-10 minutes.
