Our second grade team has worked really hard all year on ballpark estimates (aka rounding). Unfortunately, I have one student who just doesn't get it. Sometimes she is able to get it right, but other times 84 rounds to 60 and sometimes 32 rounds to 50. I'm not sure why, but she just doesn't seem to have the number sense to help her with this task. While I only have a few months left with her, I was thinking ahead to next year and how I can improve my teaching. I looked in the second grade common core standards, but I didn't find rounding. I did, however, find it in the 3rd grade standards:
NBT 3.1 - Students will use place value understanding to round whole numbers to the nearest 10 or 100.
Our district is not in a financial position to update our curriculum to align to the new standards. So, I will still be teaching rounding in the form of ballpark estimates. I started thinking about adding additional resources to my classroom and decided to make something. I'm calling it Ribbit, Ribbit, Round It.
