4th Grade Skills, when mastered, open a new world of math to your child.

This year is when your child moves from recognizing fractions to actually doing computations with them.  Where the decimal point will no longer be a mysterious dot on the page, but present new meanings to the word number!

Where geometry is no longer simply shapes on paper, but the knowledge behind everything they look at or touch.

This is a very exciting time in your kids elementary math education.

Many teachers no longer issue homework to their classes. My question is, how is a student to reinforce what is being learned if home is taken out of the equation?

You (if you are a parent) know the value of 'home' and practice - so congratulations to you!

This list of skills is based on the 4th grade level expectatoins from Washington State OSPI

These Grade Level Expectations are organized by basic math subject area for 4th Grade, based on Washington States OSPI.  If you would rather have a basic math skills requirements list organized by subject area, that includes every requirement from Kindergarten to 6th grade in one downloadable document please visit my Grade Level Expectations section.
