# MATH IN CHILDREN'S HOUSE

AIM’s Montessori preschool program enables students to learn arithmetic into the thousands. The math program builds upon indirect preparation, especially in the sensorial area. It’s built around a systematic progression from very concrete materials to more abstract operations. Here is a list of different activities and levels of math that AIM preschool students discover:

## COUNTING TO 10 & BEYOND

3 ½-year-olds may start with math by using the number rods and spindle boxes to learn the numbers 1 to 10. They learn one-to-one correspondence and learn that the number "three" doesn’t mean the 3rd in a series, but the fact that three individual things are combined together. Children then get introduced to the colored bead bars. Here, the numbers 1 to 10 are represented by differently colored beads strung together in bars. Students soon associate the number with the color; they then add the colored 1 to 9 beads to the golden 10 beads to build numbers to 20.

## THE DECIMAL SYSTEM/PLACE VALUE

With the addition of the tens board, students begin to build numbers up to 100, and soon progress to working with the golden beads, which introduce our Montessori preschoolers to the decimal system, and enable them to understand numbers into the thousands (a skill not introduced in California public schools until late 2nd or early 3rd grade!)
