Hi Samantha, Great blog on math board games. I work for LogicRoots, a company that work tirelessly to make math a fun subject for kids. We have made original math board games, app and card games that give upto 20 times more practice in math. More than that, kids are motivated to practice math more and more and bond over a fun game. Through the reviews of our games on Amazon, we were overwhelmed to see that our games have helped children with ADHD and dyslexic students as well.
I was just wondering that if you would like to test our game and check out for your self if they really work. Please contact me and we can take this further.
Structural relationship of vitamin D 3 (cholecalciferol) and vitamin D 2 (ergocalciferol) with their respective provitamins, cholesterol, and a classic steroid hormone, cortisol (see inset box). The two structural representations presented at the bottom for both vitamin D 3 and vitamin D .2 are equivalent; these are simply different ways of drawing the same molecule. It is to be emphasized that vitamin D 3 is the naturally occurring form of the vitamin; it is produced from 7-dehydrocholesterol, which is present in the skin, by the action of sunlight (see Figure 2). Vitamin D 2 (which is equivalently potent to vitamin D 3 in humans and many mammals, but not birds) is produced commercially by the irradiation of the plant sterol ergosterol with ultraviolet light.
