Multiplication Tables Placemat, Large, Multicolor

I won't list all of the features of the periodic table since there is a picture of what is included on the chart, but I will highlight my favorite aspects which I think would be most informative to others. This gets 5 stars because of its durability, size, information organization, and usefulness. The size of the periodic table of elements is approximately the size of a dinner place mat. It's a perfect size in my opinion, because it is big enough to see everything clearly while not too cumbersome to handle. I reference this while typing and reading and I have no problem holding it up and setting it aside repeatedly. The periodic table is very laminated. I say 'very' because it feels like it's been laminated 5 times and there are no uneven corners or bubbles. I am not afraid of it peeling or spilling anything on this, simply because it feels so solid and well-constructed. *I just noticed that it says 'PAINLESS LEARNING PLACEMATS' in small print on the corner. The information is very well-organized. I cannot express in words how much this simple chart has helped me with my online chemistry course. I have to look at the table of elements constantly for group numbers and masses, and going back and forth between tabs on my browser was very time consuming and, quite frankly, irritating. This chart has saved me so much hassle, and I love the fact that everything is color coordinated. I know which groups are noble gasses, nonmetals, transition metals, ect... just based on the color. Truthfully, if I lost mine and the only replacement available was $30, I would purchase it without even thinking. That's how much use I have gotten out of this. But luckily for all of us, this chart--including shipping--is available for only $4!! If you're taking a chemistry course, this is a MUST. It will save you the hassle of flipping to the front of your chemistry book a million times or trying to make out the small letters on your computer screen. I normally don't rave about products this much, but everything I have said is genuine. 5/5 LOVE IT!

This is a nice Periodic table placemat. Size is reasonably big, quality is good . However the key to help your child to learn Periodic table is to make it as much 'fun' as possible. SOME TIPS: You don't have to be focused on grades to teach Periodic table. Kids of all ages , beginning even 2nd or 3rd grade can absorb concepts surrounding Periodic table elements ( who does not understand water).It is sad we teach our kids about dead presidents right from the beginning but periodic table way up after elementary school. 1. Teach the kids just 10 Elements. Begin with simple ones like Hydrogen, Oxygen ( with Water as Example). 2. Google for H2O Chemical Formula. See how nice the images are. 3. Ask them to find what the oxygen we breath is made of 4. Ask them about Photosynthesis and that takes them to learning Carbon (and Oxygen) 5. Have them search for products on an IPad that has the elements in periodic table ( table salt > Sodium etc). Let them search in google and figure out. 5. Repeat the same for next 5 products. SUMMARY: Let the kids enjoy learning about Periodic Table, This is one area that you do not have to wait for teachers to begin teaching. Leave the brute memorization to get better grades for later years. Since I brought up Presidents, Here is a nice product to learn about American Presidents as well US Presidents Pocket Flash Cards . If indeed your children are in middle/high school, get them a dissection box (with clear rules on where to use it, how to dispose it off) and they will not only enjoy the process, but also have a chance to tell to their friends at school. Let them lose the fear of biology 20 PCS ADVANCED BIOLOGY LAB ANATOMY MEDICAL STUDENT DISSECTING DISSECTION KIT SET WITH SCALPEL KNIFE HANDLE BLADES #10 + #11 ( HTI BRAND) and Frey Scientific Choice Preserved Grass Frogs, Single Injected, 3.5"-4" (Pack of 10)

Great for kids learning division. We also have addition, subtraction, and multiplication.

These placemats are brilliant, I absolutely love them. I purchased the Periodic Table, Map of United States and the World Map. These are the size of any regular placemat and I thought it would be a good conversation piece for my teenage kids and I. It totally worked, they don't even realize that I did this on purpose but they can't help but look at it and have small talk with me about it. It is colorful, informative, wipes clean, the rear side is blank so you can quiz yourself using a dry-erase marker and great for all ages. In addition, I play bar trivia with friends so I am also trying to brush up on my general knowledge :-).

This placemat is the perfect balance between a regulation sheet periodic table and a poster size. It is 17.5 inches by 12 inches and coated in really heavy plastic. Has Atomic number, symbol, name, atomic weight, valence shell configuration (and big enough to actually read), boiling, melting point, density, crystal structure and is color coded. It does stop at 112 and we are up to (in theory 118) but that is not going to be addressed in most beginning chem classes. Also 110, 111 and 112 do have names now Darmstadtium, Roentgenium and Copernicium respectively. So a new update would be nice (hence one star off, as it was published in 2000) , but again, for beginning students this will not be an issue. *Update of review It has been updated, I just ordered a second as my first kid is going off to college to major in chemistry, and the second kid will need her own periodic table at home. The new version has 114 and 116 and the names for 110-112 are added. The rest up to 118 are not listed. However, it does have a shinier laminate, which my kids did not like as much. The old version had a non shiny surface.

Great portable quality product -- periodic table for learning- as a teacher these were purchased for individualized learning stations- they are a great price, water proof, and a great easy to read design - I purchased a bunch.

My son had this as his placemat at the table all during the year he took chemistry and then got a perfect 800 on his Chemistry AP test!! Need I say more?? Good price and great results from seeing everyday.

Rather than whining about dinner taking too long (seriously, I am not making gourmet meals here, but food takes time to get ready!!!), my kids are looking at their placemats entertained AND learning something new! My 3 year old already knows how to count to 100, but this placemat let's him see the numbers written out and the pattern of counting. It's perfect! This placemat is really sturdy, easy to clean and nice pictures that are appealing to kids. I bought a bunch of these placemats and each meal my kids get to pick out which one they want. I also like that these are super easy to keep clean and the shifting of plates, bowls, silverware, cups is not scratching my table! Why didn't I buy these sooner!?!?!
