In second grade, we spend a lot of time representing numbers in different ways. I came across a Math Thinking Map on Pinterest that I loved but was unable to locate the original source so I created one myself (if you know the original source please let me know so I can give credit where it's due).
I have used this to help differentiate in my classroom; depending on the place value skills my students need to work on, some students complete the math thinking map using a 2 digit number, whiles others might complete it with a 3 or 4 digit number. You can also use it for a number of the day! Grab your free copy here or click on the picture.
Let me know if you use it in your classroom and how it works for you!
