I’m teaching one class of 7-year-old (kindergarteners) once a week. Right now, they’re still working on learning the alphabet. I was at Home Plus (where else?) on day and saw a bucket of alphabet magnets. The price wasn’t too outrageous (about what I’d expect in a US toy store) so I bought a set. It worked out perfectly. There were 4 sets of letters and 4 kids in the class. As they learn new letters, I add them to a plastic bag.
At the beginning of each class, we sing the ABC song a few times as a warm up. Then we do rock scissor paper (to avoid fighting over colors). When that’s all done, each student has a bag of magnets. They go up to the board and have to put them up in correct order. They struggle with things like the b and the d and the q and the p, so we sing and look at our big ABC poster.
Here are a few pictures of them from the first time they did the activity.
