When I was just learning to read, my teacher had a sock puppet named Mr. Easy, whose face was a lower-case e with a dot in the enclosure to form his "eye". Mr. Easy's job was to help the vowels say their name. He would tack himself on to mat and call out to the vowel: "Tell me your name!" And we, being 5 or 6 and eager to help the vowel, would call out "A. Your name is A!" And Mr. Easy would then turn to us and ask us what word the a was trying to make. And we would shout the answer, laughing and having a great time. And thus mat became mate, them would become theme, bit would become bite, and to this day I remember Mr. Easy.
This is not intended as a glowing little remembrance, but to point out that whatever device a teacher uses to bring an idea to life is a good idea. Kids like games, they like fun, they like cartoonish characters, and they actually love solving problems. Whether the teacher uses a sock puppet or a jumping game, the important thing is that good teaching involves engaging children in a way that makes a lesson fun and memorable.
