Trinomial by Trinomial

(3 + 2 + 5) x (3 + 2 + 5) = ...? using the distributive law - not PEMDAS!

Binomial by Binomial

Can you figure out the equation he's writing?

Why Montessori Matters

Happy kids learning with materials!

 Squaring: one successive square to the next.

 Detective Triangle Game!

 Noun Sorting.

 Addition Working Chart.

 Small Constructive Triangle and Hexagon Box.

Bead Bar layout: multiplication of 4.

Hard at work!

Stamp Game also works for division, and the blank multiplication working chart challenges you to put "answers first."

Stamp Multiplication.  Can you figure out what the problem is from the layout?  Hint - multiplication is how many times we "take" a number...

The Timeline of Measurement



The Timeline of Measurement provides the cultural context for the study of measurement systems. How did measurement systems begin? Why did they change through time? What is the difference between the customary system and the decimal system? And, of course, we now know that "King Henry Doesn't (USUALLY) Drink Chocolate Milk!"

Number concepts

New students get a solid, concrete foundation of number concepts.

The Peg Board

Older students get a concrete introduction to multiples and factors before we introduce how to use them for LCM and GCF. Students love the "race" of the multiples...who will "win"?

1st grader and 3rd grader

The bead chains allow for a concrete representation of skip counting, squaring, and eventually, cubing. The bead frame allows for a complete understanding of "magic zeros." Are you really just "adding" or "moving" the zero when multiplying by a base ten? Montessori students know the answer and the reason!

Some fun with the beads!

Montessori students walk away with a solid mathematical foundation and, more importantly, a lifelong love of math and learning!

7 Triangles of Reality!

After several separate lessons on lines and angles, we used discovery-learning to find the 7 Triangles of Reality.  The kids used the Geometric Stick Box to see if they could create our grid of angles and lines.  Is a right, scalene triangle possible? Yes! How about an obtuse equilateral? No! Our "Presentation of the Stars" helped provide the cultural context of angle measurement as a degree = a day on the path of a star...
