Summary and Synthesis

We have been learning about addition and subtraction problem types. I have never heard of join, separate, part-part whole or compare.I think this is an interesting way to look at problems. It took me awhile to understand the differences of and what each one meant. These four are different structures of a problem and they describe the way a number sentence will be written. This is good for teachers because they know where to start when giving their students addition and subtraction problems. The teacher will also know what types of problems to give to the students and also what types of problems the student struggles with.
