But, I feel like it is important to restructure my classroom and what I am teaching to align with common core. Its not about simply memorizing letters and numbers anymore. There are many different aspects to reading and math.

Eunmi Yang's curator insight,

This video shows a powerpoint with visuals that can help the students understand composing and decomposing numbers. The video shows a visual representation of the number and then shows how tens are composed and why they are composed when a number is added to it. I believe that this is an effective way of teaching because the students are able to see what is really happening when they are composing numbers and so they are able to understand why something happens when they are using the algorithm method. This video is kind of like the base ten method that I used when I was teaching composing to my 3rd graders and I think that this is a great lesson to also have in addition to the base ten method lesson.
