Grade 4 Unit 6 Multiplication and Division Pt 2
Unit 6 Multiplication and Division Pt 2
Content Emphasis/ Big Ideas
In this unit, students apply their knowledge of multiplication and division concepts that were previously taught in Unit 4. Through the use of arrays, base-ten blocks, and story contexts, students develop their own strategies and algorithms for multiplying and dividing large numbers. Connections between algorithms, including student-generated algorithms and the traditional algorithm, are explored.
Standards:
- MTH.G4.4.b Estimate and determine products of whole numbers (2 digits × 2 digits).
- MTH.G4.4.c Estimate and determine quotients of whole numbers, with and without remainders (1 digit divisor and 3-digit dividend).
- MTH.G4.4.d Create and solve single-step and multistep practical problems involving multiplication and single-step practical problems involving division with whole numbers.
- MTH.G4.15 Identify, describe, create, and extend patterns found in objects, pictures, numbers, and tables (numerical).
- MTH.G4.16 Recognize and demonstrate the meaning of equality in an equation.
Skills:
- Estimate & Solve 2 digit X 2 digit multiplication

Hands On Math At Home
Collect and graph data around you: colored foods (M&Ms, skittles, fruit loops), types of vehicles in parking lots, sock colors in the drawer, etc.
Use data to determine probabilities and likelihood-what is the probability of pulling red skittle?
