# Math Mondays: 2 + 2 = 6

Is this true? Of course, most of us would immediately say no. And many of you may already be thinking that I shouldn't be teaching math (just like I think when I see someone create a polygon unit that features circles!) And you might very well be right.

For example 2 unicycles + 2 bicycles = 6 wheels. Ah ha!

Once kids realize that they can think a bit unconventionally, they can get really

creative. We do this exercise periodically just to keep our brains flexible. Sometimes students write equations for each other and then trade; sometimes they challenge me with them. Sometimes, we take time to illustrate our solutions. The one shown to the left is one of my favorites: 2 deciduous trees in the winter + 1 evergreen tree in the winter equals one tree with leaves.

I love this activity because:

**But**.. occasionally, I will post something like the equation 2 + 2 = 6 and ask students to make it true. The first time I do this, I invariably get responses of disbelief. But when I'm patient and just let everyone think through it a bit, someone will get creative and that's how it starts.For example 2 unicycles + 2 bicycles = 6 wheels. Ah ha!

I love this activity because:

- Students think creatively
- There is not one right answer
- It's active learning
- You can use it at all levels - it's not just for addition (I've had students create some pretty complex equations with this)
- You can use it as a bell ringer, fun math center idea, or when you finish early. It's even great on field trips or when waiting.
- No equipment required.

Math joke that goes with your post: When does 10 + 3 = 1 ?....

ReplyDeleteOn a clock! (Your post reminded me of that brain stumper that one of teachers did when I was in elementary school.)

Ooh... I like that one. I will have to use that this year. Thank you for sharing.
