Nowhere is there a system for teaching math that is more elegant and more straightforward than in Montessori; however, we educators must ensure that the children are deeply connecting with the materials if they are to grasp all that the materials have to offer. Without carefully designed activities that cause children to engage their “gray matter”, children can get the right answer without internalizing the patterns and processes involved. Lockhart Learning materials lead the children to a deeper understanding of key mathematical concepts and help conceptualize areas of mathematics that, in some cases, have come to prominence since Dr. Montessori’s time.

Making Math Facts MemorableMaking Math Facts Memorable
Do you feel that mastering math facts (+, x, -, ÷ tables) is harder for children now than it once was? You are not alone! Recent research indicates that activities with manipulatives are important in developing automatic recall; however many children will not spontaneously memorize facts solely from experience with them, nor from problem-solving activities. GOOD NEWS: we can use current thinking on brain-based learning to better support children without significant increase to the teacher’s record-keeping or instructional time!

Fraction Division as Invert and MultiplyShowing Fraction Division as “Invert and Multiply” with Materials

Helping children bridge from materials-based fraction division to the abstract process of “invert and multiply” has long confounded many Montessorians. But it is not difficult! It all has to do with what you do when the division is “done”. In a simple examination of how the quotient relates to the dividend, the abstract process can be clearly demonstrated. Download this FREE lesson (includes photographs) and start allowing your students to discover the relationship instead of having to show them!

Fourth and Fifth Powers of a BinomialThe Fourth and Fifth Powers of a Binomial

Montessori Elementary educators are eminently familiar with the binomial cube and the elegant way in which it concretely expresses the expansion of (a+b)3. The materials for (a+b) 4 and (a+b)5, logical extensions of the binomial cube, are less universally understood. They are often among the materials storage because no one knows how to use them. Download this FREE article, a transliteration of Maria Montessori’s discussion of these materials from Psicoaritmetica, to learn what these materials represent.
