Grade 4 GT Mathematics
Unit 4: The Number System (6.NS)
Throughout this unit, students use the meaning of fractions, the
meanings of multiplication and division, and the relationship between
multiplication and division to understand and explain why the
procedures for dividing fractions make sense. Students use these
operations to solve problems.

What will my child learn?
Students will:
Apply and extend previous understandings of multiplication and division to divide fractions by fractions.
6.NS.A.1
Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem.
6.NS.B.2
Fluently divide multi-digit numbers using the standard algorithm.
6.NS.B.3
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.
6.NS.B.4
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2).
