Here are the Common Core standards for 4th grade math.
One of the big things we're learning this year is how to multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models. (CCSS.MATH.CONTENT.4.NBT.B.5)
Examples include:
9,847 x 6 =
and
94 x 78 =
