Which is why I got really excited when I saw this Halloween decoration the other day at Michael's:

You can display this decoration 51 days before Halloween! Or can you?

What if this decoration can't display each number between 1 and 51? Would that constitute as some sort of false advertising?

This is fantastic. I remember your initial post with the wooden blocks, but these Halloween blocks add a whole new dimension to math being scary for students. Mwoohahaha!

ReplyDeletePlease tell me you bought this.

My only suggestion: don't tell students that the wooden block on the left is a zero and a nine. Have them figure out if it's a six or a nine. I think you gave them too much information by writing:

LEFT: 0, 9, _, _, _, _.

This reminds me of Jimi Hendrix: "If 6 was 9"

Great song!

BTW, here's the arrangement I came up with to account for Days 00-31. Let me know how I do.

DeleteLeft Block: 0, 1, 2, 6/9, 7, 8

Right Block: 0, 1, 2, 3, 4, 5

Days missing if you did a 99 day countdown:

33-35, 43-45, 53-55, 66-69, 76-79, 86-89, 96-99

I put the clues there because some of students were confused about what was being asked. They had never seen these cubes before and I had to explain how they worked.

DeleteI did not buy it. It's $15 and is of poor quality. The stickers seemed like they would peel right off.

Your work looks correct to me. How many other ways could have have done it?

One thing I thought of was, what if we didn't need to use both blocks to represent days 1-9? What number should I replace the zero with to make it the numbers continuously go as high as possible?
