The set contains one card each of the numbers 1-9, the decade numbers (10, 20, 30…), the hundreds (100, 200, 300...) and a 1000 card. This allows children to make all the numbers from 1 to 1999.
These Place Value Cards (aka Hide Zero Cards) allow children to see the value of each digit within a number. The small numbers in the upper left-hand corners of the cards shows the expanded notation to remind children that the “3” is really worth a “30.” The back of each card shows the MathRack’s visual representation of each number, to help children build spatial relationships for numbers.
If you want to print your own Place Value Cards (aka Hide Zero Cards), you can find the blackline master (for the 1-100 cards) on our Free Downloads section.
