Unit 3 MultiDigit Multiplication and
Division Grade 4 Math 


Description: Students will multiply a singledigit number times a
multidigit number and a twodigit number by a twodigit number. Students may use strategies such as the
standard algorithm, arrays, area models, and mental strategies as well as
properties of multiplication to multiply. Students will also model, write and
explain division by onedigit divisors.
Students continue to become fluent with basic facts. Problem solving situations should be used whenever
possible including problems involving measurement. Area of rectangles provides one context for
developing such understanding.
