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:
4.CE.2 The student will estimate, represent, solve, and justify solutions to single-step and multistep problems, including those in context, using multiplication with whole numbers, and single-step problems, including those in context, using division with whole numbers; and recall with automaticity the multiplication facts through 12 × 12 and the corresponding division facts.
4.PFA.1 The student will identify, describe, extend, and create increasing and decreasing patterns (limited to addition, subtraction, and multiplication of whole numbers), including those in context, using various representations.
Skills:
- Estimate & Solve 2 digit X 2 digit multiplication
- Estimate & Solve quotients 1 digit divisor and 3 digit dividend
- Practical Problems involving multiplication and division

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?
