This is a set of 24 task cards aligned to the first grade common core standards:
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).
Students will need to identify number when shown groups of tens and ones and separate numbers into groups of tens and ones.
QR Codes are included so that students can check their work.
*Update: 2 versions of the task cards are now included: one with QR codes, and one without
