Children can test their math skills and learn the Pythagorean Theorem alongside young Pythagoras in this STEM adventure. Pythagoras' curiosity takes him from Samos to Alexandria, where he meets a builder named Neferheperhersekeper, who introduces him to the right angle. While building, Pythagoras uses geometry to learn how to measure angles and discovers all he needs to know about right triangles. With playful puns and wordplay Ellis creates the perfect STEM/STEAM resource for introducing young readers to a fundamental mathematical equation. A fun and accessible way to get young minds asking "what's your angle?".

Mouse and her friends want to play tug-of-war, but they'll need to use some everyday math to figure out how to make teams that are equal. As Mouse looks at various solutions she is not sure what it means to be equal. Nothing works until Mouse starts to think about it mathematically and divides the teams based on weight. Wonderful illustrations capture Mouse and her animal friends from whiskers to tails as they work to measure and equalize their teams based on size, weight, and effort. A perfect addition to any STEM/STEAM collection that shows readers how math can be used in everyday problem solving.

Crack the case with George Cornelius Factor in this entertaining math adventure that introduces simplified and reduced fractions with equal parts intrigue and humor. When a valuable fraction goes missing, George Cornelius Factor (a.k.a. GCF) vows to track it down. Knowing that the villainous Dr. Brok likes to disguise his ill-gotten fractions, GCF invents a Reducer-half ray gun, half calculator- that strips away the disguise, reducing the fraction to its lowest common denominator and revealing its true form. With the Reducer in hand, George seeks out Dr. Brok in hopes of retrieving the missing fraction. Back matter includes more detail on simplifying, or reducing, fractions.
