- For elementary school students
- Color-coded numerals on white cardstock. Lamination and cutting required.
Note: Millions cards are considered support material and are not automatically included in classroom sets.
Montessori color-coded cards for composing six-digit numerals. Color-coded cards representing millions, hundred thousands, ten thousands, thousands, hundreds, tens, and units. Visualization of place value, visualization of zero as place holder, aid in the understanding and reading of multi-digit numerals

Secure small cards with rubber bands and store in same sorter as large or in separate hardware drawers, boxes, or envelopes.
Scope and Sequence Chart (Click here)
The teacher's experience and the sequence of skills in the students' basic math program are the best guides in determining which skills should be introduced first. In general, the scope and sequence chart above can be used as a guide.
A number of sets for younger children are "color coded." Some teachers present all the levels with an exercise set, while others prefer to present all the blue (two-digit) exercises, progress to the pink (three-digit), and culminate with the green (four-digit).
Other skills such as Roman Numerals require no prerequisites other rhan an understanding of place value. Such exercises can be presented any time.
