The squish-o-matic machine is busy squishing numbers as kids practice taking an expanded-form number and writing it in standard form. After that, kids must take a number in standard form, and the squish-o-matic machine will convert it to expanded form. Using the squish-o-matic, kids will effortlessly understand place value and playfully manipulate expanded forms of numbers.

Expanded form is a way to represent numbers by showing the place value of each digit. In expanded form, a number is separated into the value of each digit. For example, the number 1234 would be written as 1000+200+30+4. This helps kids understand the place value system, showing them how each digit in a number has a different value depending on its position or place in the number.
