In room 207, we are in the midst of comparing numbers, utilizing our knowledge built on place value. My students struggle in the abstract thinking sense of how large a number truly is, so we are working hard to support and modify assignments in order for each child to be successful. Some utilizing base 10 blocks, others looking at the highest place value first and comparing, and for some that means providing the picture representation of base 10 blocks and additional scaffolds in order to compare numbers.
Here is one activity we are using in order to help students visualize how a number actually looks, using 4 ways written they can see the standard form, written form, base 10 block construction, and expanded form. This provides students with the knowledge to access all of these strategies when comparing numbers.
I hope your students find this useful, enjoy!
