Common Core State Standards for Multiplication
Fourth Grade: Multiply a whole number of up to four digits by a one-digit 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.
Fifth Grade: Fluently multiply multi-digit whole numbers using the standard algorithm.
