This looks like a great game! I'm just starting probability with my class, and will definitely try it out! Just a suggestion... if you added labels to your posts you could indicate math skills making it easier for readers (like me!) to see if you have other posts about probability, or whatever, without scrolling through all of your posts.

Thanks for the idea! :)

1. Thanks, Erin! I'm not sure how to do the labels...I will check that out!

3. Wow....Just wow....
Im doing a school project on probability and im definitely going to use this,Thank you sooooo much!!!!!!

### Math Class - First Day Activity

Rectangle of pentominoes Many 6th graders seem to have a pretty negative attitude about math, so I try to do something interesting to "grab" them during our first class. Last year, during the first math class, we spent part of the period working with pentominoes. Before working with the pentominoes, however, we played a name game so we could learn each others' names (I find it impossible to start anything else if I don't know some names, and fortunately, I learn them fairly quickly). rectangle outline For the activity, I divided the students into groups of 3 or 4. The directions for the activity were not complicated - the task was to make a rectangle, using all of the pentominoes. I gave students an outline of the rectangle, as pictured to the left, so they would know the correct size of the rectangle. The squares in the grid are each one inch. The rectangle is 5 squares (inches) wide and 13 inches long (13 inches includes the row that has the "Pent

### Ratios Fold it Up!

Getting started with ratios! We pretested ratios, rates, and proportions last week, and I found mixed results in the item analysis. I was surprised to find that very few students were able to write a ratio (the pretest question was: there are 2 hamsters and 1 gerbil - write a ratio of gerbils to hamsters). It wasn't that they wrote the ratio as hamsters to gerbils rather than gerbils to hamsters....they either left it blank, or wrote something that did not resemble a ratio. So, I was glad that I had prepared a couple of Fold it Ups for them to use this week! I think this is the first time I've used this version of Fold it Up (with the triangles folded in) this year, and a few students commented that they like this version better than others (like the one I made for Wed...bummer), because this type won't rip as easily.
