CCSS 4th Grade Numbers and Operations in Base Ten 5.1Multiply 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.Lesson to be used by EDI-trained teachers only.
To multiply is to do repeated addition of equal groups.•Factors are the numbers being multiplied.•The product is the answer to the multiplication problem.•There is a place-value strategy1 for multiplying by multiples of 10, 100, and 1000.
