Big Ideas: Each digit of a number has a value depending on its place within the number. The hundreds place tells you how many hundreds are in a number, the tens place tells you how many tens are in a number, and the ones place tells you how many ones are in a number. Though check writing is a skill that people need later in life, you can only write out checks if you know how to write out number names. In this task, students are "buying" a variety of toys while fulfilling a "must-haves" list in order to write out number words that students often have trouble writing. Vocabulary: digit, value, place, numeral, number, word form, number parts
