Notes for Session 4, Part A


Note 2

If you are working with manipulatives, notice that a merger requires a physical action. If no physical action is required, you can be certain that it is a "parts of a whole" type of addition.

Note 3

Many different types of problems require addition, and you should become familiar with each type so that you know when to use this operation. Learning the names of the different types of addition problems, however, is not the important part of this session.

As you probably noticed, some of the addition problems actually require subtraction. It is important to recognize the relationship between addition and subtraction.

Note 4

As with addition, many different types of problems require subtraction, and it's important to become familiar with each type. Again, though, learning the names of the different types of subtraction problems should not be your burning goal in this session!

Note 5

As with addition and subtraction, you should become familiar with all the different types of problems that require multiplication -- but don't put too much effort into memorizing their names. It is important to recognize the relationship between multiplication and division.

Note 6

Finally, you should become familiar with all the types of problems that require division so that you recognize when to use it. But knowing the names of these different types of division problems is not the important part of the session. It is important to recognize the relationship between multiplication and division.
