Addends, and sequences, and digits...Oh my!

Over the last several days in math we have covered the concepts in the title of this post. Students know that when an addend is missing, "you don't add, you subtract". Sequences lead to multiples of numbers, and studying of digits prepares students for place value concepts. While learning all these new concepts, we have also worked on objectives specific to each child.

Back to the Ole Grind...

With testing behind us and five more weeks of school remaining, it is time to squeeze in as much learning as possible. Math students will be making a subtle change this week. Seventh grade students will begin working in the Saxon 87 book and sixth graders will move up to the 76 book. Everyone seems excited about the change and the challenge.

Missing addend problems tend to confuse students. Using the following self-talk will help students become more comfortable with this type of problem.

First, in an addition (or subtraction) problem, where is the largest number found? (In addition, it's on the bottom; in subtraction, it's on the top.)
Second, does the problem give me the biggest number?
Finally, if I have the biggest number, subtract. If I don't have the biggest number, add.
Rule to remember: Adding gives bigger numbers; subtraction gives smaller numbers.

So Far in Math...

This week the math classes will get with off and running with pre-tests and placement tests behind us. Sixth graders started with sequencing numbers. This will "nimble" their reasoning skills as they recognize the relationships between a series of numbers. This week we take on place value, expanded numbers, and a review of the addition and subtraction algorithms. Most seventh graders completed testing and are ready to begin instruction for negative numbers.
