Does anyone use any of her products for math centers or activities? Someone on another site referenced her materials, so I looked them up. There is a ton of stuff, so I am just wondering if anyone could give an opinion of what is good or not so good about this stuff! It looked REALLY good to me, but I didn't spend a lot of time looking. Thanks for any info!

Marcy Cook is my math hero! We do a tile teaser every morning. I have all of her other books and use them regularly. If you have the chance, take one of her workshops. She's a great presenter!

There's so much to choose from. Can anyone tell me what book or books and manipulatives to begin with?

These are my favorites: COLOR IT ON THE HUNDRED CHART MATH MODELS WITH MAGNETIC MATERIALS TILE TEASERS COMMUNICATING WITH TILES FINDING X ...ALGEBRA BEGINNINGS MENTAL MATH WITH TILES & THE HUNDRED CHART I have the kids make their own set of tiles with 2"x3" pieces of construction paper. They write the numerals with a black pen so that when the tiles are held up I can see them across the room. They keep them in an envelope in their math project folder. It's rare that we have to remake the sets during the year. I put up a tile teaser each morning and each student who comes up with a unique correct answer records their answer on a sticky note and puts it on the chart. We keep track of the number of days we have gone without a problem getting no answers (we call it a stumper) and the high number of solutions that one problem gets). Right now my class is trying to break the record held by last year's class of 8 days without a stumper and a high of 235 solutions.

Yes, a tile teaser is a math problem. Each one uses the digits 0 - 9 one time and the tiles are arranged to make true statements. I make a chart with the placement for the digits for that problem. For example: # + # = ## # x # = # # + # = # Students work with their own set of tiles and come up with solutions. It's a great way to get their math brains engaged before we start our formal lesson.
