Even the photo has the pen in it. 95 dollars for cards and no pen. Not a good deal at all.

I can't believe you guys don't even send a pen with the complete math set. You should put a disclaimer saying you must order a pen. It's deceiving. I have 8 sets now and no pen. Extremely deceitful.

My students love to grab a box and a pen when they've completed their assignments early. Great for independent play.

Both of my homeschooled kids have used these to strengthen their recall on number facts. An excellent teaching supplement.

This is SUCH a great product that all of my children can use with their own pen and ability level of cards. Wish I had one of these for every student in my classroom too!

My students absolutely love these! I love that they get to play a game and review necessary math They're a great independent activity because you can turn the volume down and students can still see if they are correct or not because there is a light.

I like this activity because the students can check themselves. I like using it and having them solve and the first to solve then gets to see if they are right with their power pen. It is also great for students to do on their own.

I love these for independent practice. With the pen notifying of wrong/right answers, my children are able to quiz themselves.

Both of my daughters enjoy using these cards and challenging themselves.

Love using these to help.with my intervention students, especially right before state testing.

I love using these for independent math work time. Students are able to answer questions and find out if they are correct or incorrect without having to ask an adult. Great for remedial support and even extension.

This is a really nice alternative to doing math problems with a paper and pencil. The reading comprehension stories are really neat to. My son and I did further research on the reading comprehension and my son actually said, that was actually kind of fun. He also chose it over going outside
