Imagine a golf coach who never plays golf. An English Literature teacher who doesn’t enjoy reading books. A lifeguard who can’t swim. Pretty absurd, right?

Math anxiety is a real thing, a new brain imaging study by Stanford researchers has confirmed. In a study in the journal Psychological Science, researchers found that there is increased activity in the brain region linked with fear in the brains of second and third graders with math anxiety. from Pocket Here is where I […]

If Levi Vaughan, a 5-year-old kindergartner in Braidwood, Ill., makes it through math class without a meltdown, it’s a good day. The transition to school has been tough in other ways for Levi, said Stefanie Vaughan, his mother, but math has been uniquely challenging. from Pocket Here is where I got this article from.

When do you know it’s time to try something different in your math lesson? For me, I knew the moment I read this word problem to my fifth-grade summer school students: “On average, the sun’s energy density reaching Earth’s upper atmosphere is 1,350 watts per square meter. from Pocket Here is where I got this […]
