Math Mammoth Place Value 1 focuses on place value and two-digit numbers and is primarily meant for first grade level math.

When children count, they basically just learn numbers as some kind of continuum that goes on without end. With simple counting, your child might not catch on to the inherent structure of the number system. Our number system is based on the idea that if you have lots and lots of objects, the efficient way to count and denote them is with groups of tens, hundreds, and thousands Ñ not individually.

The crucial point in understanding the concept of place value is therefore that a certain position represents a certain size group. The digit in each position tells us how many groups of that size there are. For example, in the number 2,381, an adult already knows that the 8 represents eight tens, and not just "8" and that the 3 represents three hundreds, and not just "3". The place of the digit tells us the size of the group, and the digit itself tells how many of that group.

The initial lessons of the book that introduce tens and ones use a 100-bead abacus extensively. This 100-bead abacus or school abacus simply contains ten beads on ten rods, for a total of 100 beads. It is not the special abacus used by the Chinese or the Japanese. Each bead simply represents one. The 100-bead abacus lets children both "see" the numbers and use their touch while making them.

You will need to purchase this school abacus separately, such as on Amazon, or make your own.

The abacus is used in the first lessons, but it is not the only model used in the book. We also use base-ten blocks as a visual representation of two-digit numbers. If you own a set of base-ten blocks (manipulatives), you can use them along with the visual exercises, if desired.

Moreover, we also use number lines and the 100-chart. Number lines help to visualize how numbers continue indefinitely and also relate to the concept of measuring. The 100-chart helps the child to be familiar with the numbers below 100 and find patterns in the number system.

While most of the lessons in the book focus on place value, students also practice adding and subtracting multiples of ten, and rounding numbers to the nearest ten. The two lessons near the end of the book about tally marks and graphs are real-life applications of two-digit numbers. The last lesson about regrouping can be challenging, thus is optional.

A Revolution of Faith and Freedom
Format: Hardcover
Eric Metaxas’s Revolution: The Birth of the Greatest Nation in the History of the World presents the American founding as far more than a political dispute over taxes or power—it is portrayed as an epic struggle between liberty and tyranny, virtue and corruption, good and evil. Through vivid storytelling and rich historical detail, Metaxas casts the Revolutionary era as a moral drama in which ordinary men were called to extraordinary courage against overwhelming odds in their fight for freedom. The book compellingly shows how patriots like Samuel Adams, Patrick Henry, John Adams, Abigail Adams, Benjamin Rush, James Otis, Henry Knox, Paul Revere, John Hancock, Thomas Paine, George Washington, Martha Washington, and others, understood the conflict not merely as resistance to British overreach, but as a defense of God-given liberty against arbitrary, and often brutal, power. A particularly striking theme throughout the book is the Founding Fathers’ deep reliance on Divine Providence. Metaxas highlights how many believed that human rights flowed not from kings or governments, but from God Himself, and that the outcome of the Revolution ultimately rested in His hands. Prayer, biblical conviction, and appeals to Providence are woven into the narrative, reminding readers that the Founders often saw themselves as instruments in a larger story unfolding under God’s sovereign care. Indeed, Providence often revealed His hand in altering the weather and divinely guiding the patriots as they fought the British forces. The result is a sweeping and engaging account of America’s birth that frames the Revolution as both a historical and spiritual struggle, fought with courage, conviction, virtue, and faith.

A New Classic
Format: Kindle
I pre-ordered, so I was able to get the PDF and start reading early. Of all the books I own on the American Revolution, I think this one stands to become my "go to." It is encyclopedic in scope, but deftly avoids becoming a drudgery or a slog through a mire of textbook facts. Somehow, Eric has managed to include a great deal of detail without losing any of the drama. It’s the story that rises to the fore in a gripping tale that just happens to be true (and much more than that, is our heritage). All the trademark “Metaxas” hallmarks are here: judiciously placed humor and lightheartedness that never descends into silliness, seriousness that somehow never lacks in winsomeness, depth that never smothers. He manages to portray both the soberness that the subject deserves without losing the hopefulness that the story of the Revolution should inspire in us. And along the way, you’ll find yourself better understanding what “went down” and (just as importantly) what it means to you today. Excellent work. If you think another history book on the American Revolution cannot inspire you or keep your attention, this one is up to the challenge.

The History Teacher I Always Wished For
Format: Hardcover
With his trademark wit and his eye for those wonderfully absurd details that most historians tend to overlook, Metaxas drew me deeply into the story. I found myself laughing out loud one moment and profoundly moved the next. The tiny anecdotes and humorous asides were not distractions at all — they were precisely what made these towering figures suddenly feel human and unforgettable. Eric makes these historical figures flesh-and-blood again. He brings both heroes and villains vividly to life in a way that makes the drama of America’s birth feel immediate, thrilling, and deeply personal. In short, Eric Metaxas is the history teacher I always wished I had. At 600 pages, this book reads with the ease and momentum of a paperback novel, yet carries extraordinary depth and scholarship. In the end, I came away with a renewed love for American history and a deeper gratitude for the souls who made this great country possible.
