In this unit, students deepen their understanding of number relationships by identifying and describing arithmetic patterns. They make connections between patterns and properties of operations. Students also begin to apply their understanding of pattern to strengthen computational skills and strategies.
Key Concepts:
 We can use our understanding of place value to multiply multiples of 10.
 We can find patterns in the number system and explain them using properties of operations.
 Picture graphs and bar graphs can have scales other than 1.
Prior Knowledge Needed:
 Represent and solve problems involving multiplication and division; Grade 3, Unit 1; 3.OA.A
 Apply properties of operations as strategies to multiply and divide; Grade 3, Unit 2; 3.OA.B.5
 Display measurement data by making a picture graph and bar graph with a scale of 1; Grade 2, Unit 9; 2.MD.10
Units on the Horizon:
 Developing strategies for multiplication and division (Grade 3, Unit 9)
 Using multiplication and division to solve measurement problems (Grade 3, Unit 14)
 Using multiplication and division strategies with larger numbers (Grade 4, Unit 2)
