Rainer's Scribe

today in class we did mental math, minute 21.


we learned about pentominoes. a pentomino is made up of 5 squares. there are only 12 unique pentominoes. rotation symetry ( rotating) still makes an identical shape of the same pentomino while reflection symetry make the flipped image of the pentomino. also the pentominoes are named after the letter they look similar to.

the growing post is due monday. you must create your own post or you may do it on pencil. for an example look at mr.reece's growing post on the grade 7 math blogorama. questions are due on monday, may 15th.

next scribe is ^_^
