Unit 4 is typically a seven-week unit taught from February to April.
Mathematics is the study of patterns and relationships. In this unit, students explore the patterns that exist in the multiplication and division of multi-digit numbers and within the measurement system for time.
In Grade 3, students multiplied multi-digit by single digit numbers and practiced a variety of strategies for multiplication and division. Earlier in Grade 4, students developed fluency with single digit multiplication and division and applied their knowledge of factors and multiples to whole numbers and fractions. In this unit, students examine the patterns in multiples of ten and the inverse patterns that occur in division. They refine and apply the strategies learned in Grade 3 to multiply multi-digit numbers and divide multi-digit by single digit numbers. Students also recognize that the context of a division problem determines how any remainder will be used.
Grade 3 students learned to tell time to the minute and to determine elapsed time using clocks and calendars. In this unit, students tell time to the second and investigate equivalent periods of time. They determine elapsed time without the use of manipulatives and use elapsed time to determine start and end times.
