Quote of the Week “ It turns out that math anxiety is contagious. When adults are anxious about their own math ability, it rubs off on their kids and it affects whether they choke or thrive. But just as we can put limits on others, we can take them off. My research team and I have shown that when we help parents do fun math activities with their kids -- like bedtime math, fun story problems to do with your kids -- not only do children's attitudes about math improve, but their math performance across the school year improves as well." Sian Leah Beilock Why we choke under pressure -- and how to avoid it
