### Common Core and Multiplication Tables

Much has been said and written about the use of Common Core standards in today's classrooms, particularly when it comes to CCSS math standards. Case in point: some educators claim that mastering multiplication tables is less important in the Common Core. But is this claim really true? Let's take a deeper look. Multiplication and the Common Core When it comes to multiplication standards, here's what Common Core has to say: CCSS.Math.Content.3.OA.C.7 Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers. In a nutshell, the more you care about developing higher-order mathematics, the more important fluency becomes. Now, let's deconstruct a few Common Core assumptions as they relate to math.

### 5 Principles of Cognitive Growth

In a 2011 Scientific American article, behavioral therapist Andrea Kuszewski reinforced a concept that continues to gain traction today--namely, that it's possible to improve one's native intelligence. In the past, even respected scientists assumed that intelligence was purely genetic and unlikely to change over time. Nowadays, neuroscientists and cognitive therapists recognize that fluid intelligence (e.g., the capacity to learn and process new information) is the reality. More importantly, people can boost their fluid intelligence by improving their working memory. But how? Five Principles According to Kuszewski, you don't have to be a genius to improve cognition. Even those with low IQs can grow in fluid intelligence. To quote the author, "what doesn't kill you (will make) you smarter."

### How To Evaluate Educational Software Games

Math video game characters Do you know how most people evaluate educational games? Quite simply--they don't. For example, consider Dragon Box, an affordable, highly engaging, and extremely educational math video game on algebra. If Dragon Box were a car, it would probably be named Car of the Year. So what percentage of algebra teachers or parents do you think will be adding it to their toolbox this year? At a rough guess: probably less than one percent. ST Math, Dreambox, and Big Brainz are three other great programs that can make a significant impact on children's education. Yet how many math teachers or principals have even heard of these programs? And how many have taken steps to evaluate them to see if they're truly helpful?

### Can Technology Stimulate Mental Development in Young Children?

A guest post by Dr. Eugene Emmer, medical entrepreneur and author Imagine Learning now publishes monthly guest posts in order to stimulate conversations about K12 education across the country. Opinions expressed herein are those of the individual author and may not necessarily reflect the official opinion of Imagine Learning.   As a physiologist and parent, I have long been interested in the impact of early childhood education on the child's developing brain. Over the years, an increasing number of scientists have devoted lab research to brain development and function. Their findings are not only fascinating, they also show how important proper stimulation is for the developing brain. For example, years ago I read an intriguing study that demonstrated a marked increase in hippocampal neurons in adult mice living in an enriched environment. Basically, the study showed that young rats raised in a stimulating environment had better-developed brains than rats raised in unstimulating environments. During this study, scientists raised two groups of rats. One group lived in an enriched environment that included toys, tunnels, wheels, and so on; the other group was raised in an empty cage with only food. Scientists showed that the rats raised in the enriched environment developed more hippocampal neurons than the rats raised in an empty cage. The stimulating environment had developed each rat's young brain much the same way that lifting weights develops muscle.
