Grade 4 Unit 4: Multiplication & Division

Unit 4: Multiplication & Division


Content Emphasis/ Big Ideas

The focus of this unit provides students with foundational knowledge and skills that will be needed for more advanced work with multiplication and division. Students will work on building fluency with multiplication facts through 12 x 12 and the corresponding division facts by exploring strategies for deriving facts. In context students will estimate, represent, solve, and justify single step and multistep problems (two-digit by one-digit and three-digit by one digit) multiplication problems.

Students are also expected to apply addition and multiplication properties to think flexibly in order to choose appropriate strategies to solve problems accurately and efficiently.  Students will also estimate, represent, solve and justify division with whole numbers. Students will apply their understanding of addition, subtraction, and multiplication when engaging with increasing and decreasing patterns.

Standards:

  • 4.CE2 a-e, g (i, ii only), h-k 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. (PRS 2)
  • 4.PFA1 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. (PRS 6)
