A worksheet for students to use when learning to write two-digit numbers in expanded form.
Use this place value teaching resource in the classroom to help students decompose two-digit numbers and understand that two-digit numbers are comprised of tens and ones.
Print out a group set and slip them inside of dry erase sleeves for students to use with a dry-erase marker during math centers and then wipe clean.
Students roll two dice and select one die as their ‘tens’ and one die and their ‘ones’. Students record the 2-digit number they have rolled, make it using Base-10 blocks, draw what they have made, and write it in expanded form.

Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
10 can be thought of as a bundle of ten ones — called a "ten."
The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones.
The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four, five, six, seven, eight, or nine tens (and 0 ones).
Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
