Construct viable arguments and critique the reasoning of others.

Math lessons are not tagged with the practice standards, so no weeks are listed.

What it means for your child

Your child learns to explain why an answer is right and to listen to and question other people's reasoning.

Try it at home

1. Ask, 'How do you know?' after your child gives an answer, even a correct one.
2. Solve a problem with a small mistake on purpose and ask your child to find and explain it.
3. Ask your child to compare their method with yours.
