Kids love to read jokes, it's a great way to practice those new skills they're learning. Plus if they understand the joke, you know their comprehension is good too!
Once you have copied them, laminate them, then cut them out and tape the color heart on top of the black and white heart. The students will read the joke first, then lift the heart to see the answer.
Oh my! I wish you would have asked me that before giving me a lower rating. I'm happy to check into that and make it right for you. I'm so sorry. I am not at my home computer right now, but when I get there, I'll be happy to check into that for you.
P.s. mgarling, please email me at email@example.com and I will be able to get you a new set. For now, I've deactivated the jokes.
