CCSS for Math

The Common Core State Standards for math include standards for mathematical processes to help students think like a mathematician.  These practices are:

  1. Make sense of problems and persevere in solving them.
  2. Reason abstractly and quantitatively.
  3. Construct viable arguments and critique the reasoning of others.
  4. Model with mathematics.
  5. Use appropriate tools strategically.
  6. Attend to precision.
  7. Look for and make use of structure.
  8. Look for and express regularity in repeated reasoning.

The CCSS for math are designed to be more focused, coherent and rigorous.  Ideally, under the CCSS students would be asked to do things like: explaining the meaning of a problem, asking “does this answer make sense?”, breaking a problem into smaller parts, asking clarifying questions, using math tools, looking for patterns when solving problems, and finding their own mistakes.

Your child’s teacher will be learning more about the CCSSM this year and work to realign their curriculum to these standards.  Feel free to talk to your child’s teacher to understand what is being taught at school and what you can do at home. Talk to your child about thinking like a mathematician.  Explain to your child why it is important to be a problem solver, to enjoy mathematics, and to see how it is a major part of their world today and always.  Finally, find ways to have fun with Math with your child – dig right in and work through some mathematics problems!

The following are required fact fluencies.  Note that facts with sums of 20 or less should be memorized.  However, solving equations with sums more than twenty should still be quick and effortless.
