Caleb loves writing on the dry-erase easel (who wouldn't, right?), so that's where I typically have him practice spelling. He actually loves for me to give him words to spell/write on there.
Pretty sure what he loves the most, however, is giving himself a "grade" after he has finished. And, I had started the habit of writing a 100% (using the 2 zeros to make a smiley face of course) on the board after checking his work.
Although now, 100% is just not sufficient for him. Since Daddy taught him that the number 1 million has SIX(!!) zeros, he's all about that number. So today's spelling "test" got a 1,000,000%.
