No real number multiplied by itself gives a negative result. So what’s the square root of −1? Mathematicians call it i. It’s an imaginary number, but it is used in electrical engineering, signal processing, and more! So if someone says math isn’t imaginative, tell them about i.

In math, sometimes we solve real problems with numbers that don’t even exist. For example, no real number multiplied by itself gives a negative result. So what’s the square root of −1? Mathematicians call it i. It’s known as an imaginary number, but the math built on it powers

What’s a penny worth? Not much today, but with compound interest, where money invested earns you money on what you invested and what you earn, it can add up over time. In 1,000 years at 4% interest, a cent becomes over 1 quadrillion dollars (12 0’s)! A penny for your thoughts?

Grade levels are a social construct. Feeling like your child is “behind”? Behind who? Every child learns differently. That’s why we use CTCMath. It meets each child where they are. Start your free trial: CTCMath.com

My PSA for today? Grade levels are a social construct. 👀 The pressure homeschool moms feel when their kid is “behind” is real. But behind who? Behind what? A system that was never designed with your child in mind? Your kid is not a data point. And their learning journey was

What’s an old penny worth? Not much today, but with compound interest, where the money you invest earns you money on what you invested and what you earn, it can add up over time. In 1,000 years at 4% interest, a cent becomes over 1 quadrillion dollars (12 zeros)! A penny for

Did you know April is Mathematics Awareness Month? 40 years ago, President Reagan made it official. We think it's worth celebrating. Because when a child finally gets math — really gets it — something changes. Not just in their grades. In the way they see themselves.

Christy Faith is asking a question every homeschool parent needs to hear. Have we been teaching math wrong? Not just recently. For a very long time. You've probably heard of the science of reading. That movement changed how the world teaches kids to read. Researchers are now

CTCMath just won the Blue Ribbon Award for math from the Homeschool Influencer Network at The Old Schoolhouse. The real credit goes to the families who trusted us. Try it free: CTCMath.com

CTCMath has been awarded the Blue Ribbon Award for math by the Homeschool Influencer Network at The Old Schoolhouse. We're grateful. But the real credit belongs to the families who trusted us — and the students who did the work. If you've been wondering whether CTCMath is the

Artemis II sent humans further from Earth than anyone has traveled in 50 years. That doesn't happen without math. Trajectory. Fuel ratios. Re-entry angles precise to fractions of a degree. Get it wrong by a tiny amount — the crew doesn't come home. Space runs on equations.

Up to 40% of primary teachers struggle with math anxiety. Students often develop it too. The sobering reality - and why this conversation matters. Watch this.

Nathan King puts it perfectly. Hand a violin to a student who's never been taught how to play. Tell them to make something beautiful. It doesn't work. Not because they lack talent. Because they haven't been shown how. That's exactly how inquiry-based math works. We put the

Explicit instruction. It's not about silence and copying. It's about order. Model. Engage. Practice. Coach. Then explore. Get the order right and everything changes. Watch this.

Nathan King clears up one of the biggest misconceptions about explicit instruction on Christy Faith's podcast. It doesn't mean sitting in silence copying from a board. It means doing things in the right order. Model how to do the math. Let students engage with it. Give them lots

Archimedes stepped into his bath and water spilled over the edge.That's it! He realized how people could measure any irregular shape using water. Volume = water displaced. He ran through the streets shouting "Eureka!" Just think: next time you're in the bath you're doing math.

Math fact: Infinity plus one still equals infinity. Wait... what? You can add ANYTHING to infinity and it doesn't get bigger. One million plus infinity? Still infinity. It's like infinity is mathematically unbeatable. P.S. Math is way weirder than school makes it seem.
