-Addition and subtraction are related. Addition is used to name the whole when the parts of the whole are known. And subtraction is used to name a part when the whole and the remaining part are known.
-Multiplication and division are connected. Multiplication should be taught the students start writing repeated-addition equations to represent what they did as an equation. Division should be introduced shortly after that.
-There are properties for addition/subtraction and multiplication/division to help remember and learn how to add/subtract and multiply/divide.
-Models can be used to help visualize a problem. This helps children better understand math sometimes because it helps them see it worked out and to give meaning to a number sentence.
How do these ideas inform your understanding of teaching and numbers?
These ideas help inform my understanding of teaching and numbers because it made it a lot clearer on the importance of how multiplication and division are related and why they should be taught together. It also talked about models and how they are good tools for teachers to use to help visualize math problems for students. I will definitely use models in my classroom because I believe that all students learn differently and some students will need models to help understand the meaning. There are also different properties to follow that I will teach my students because some students learn better through memorizing these properties and applying them.
