Invisible Math

Math is invisible?  What does that mean?

Well, these parts of math aren’t really invisible, but we do have plenty of 1’s that like to hide and only pop out when needed.

For example:                        y = 1y                              or                        -m = -1m

Last week my student’s were combining like terms, so it was crucial that they recognized those invisible 1’s.

On Friday, I was looking through some old interactive notebooks, and came across a few pages titled, “Invisible Math” from the beginning of semester 1.  Here is what the handout looks like:


How can you use this handout?

  • Three-whole punch this handout and give to students for them to put in their binders.
  • For teachers using interactive math notebooks, you have a few options.
    • Option 1:  have students cut out the cards and paste into their interactive notebook
    • Option 2:  have students fold in have and paste into the notebook.
