Over the years I have created many Memorama sets, some of which are always handy for my fast finishers to play with and others which I bring out during certain themes to reinforce the vocabulary we are focusing on. When we play as a whole group, I like to add an additional twist, an additional layer to our playing to kill two birds with one stone as it were.
-I call on a kiddo to name a number- I then flip the corresponding card over and we name the picture.
-I call on a second kiddo to name another number- I flip that card over and we see if we have a match. If we do, '¡Yupiiiii! ¡Un par!. If not, 'Ay, ay, ay' or '¡Caracoles!'.
I continue in this manner for the duration of the game (I usually only play as a whole group for 10-15 minutes as my youngers tend to get squirrelly). We then count up the number of matches and I record how many...sometimes we play to get our best number of matches over the course of a few classes or we play in competition with other classes in that grade level. I love being able to incorporate numbers into the activity- as an alternative, you could affix letters of the alphabet or small pictures of well known vocabulary!
