I would like a clarification of which grade level is the first grade level to introduce and work with decimals. It is my understanding that it is in 4th grade. As a person that provides professional development to teachers, the Progressions, Illustrative Mathematics, and this Forum are where I refer teachers to clarify their understanding of what the Standards are asking the students to learn and what it might look like. There are two Illustrative Tasks for 2nd grade that I am concerned send the message to teachers that they are to add $1.35 + $1.25, “Pet Shop” and “Choices, Choices, Choices”. I would like to teach the teachers the correct expectations for money and the use of decimals in 2nd Grade. Thank you!
