General
Students will learn the multiplication strategies for the times 3 facts. Instruction and practice will cover drawing arrays, skip counting, and adding one more group to a times two fact.
Standards
CCSS.Math.Content.3.OA.B.5
Learning objective
Students will be able to solve times 3 multiplication facts.
Introduction
Students will discuss the meaning of “tri” as it relates to the number 3—the multiplication facts they will be learning.
Instruction
The first strategy discussed is working with an array: objects in columns and rows to represent multiplication facts. Students will match arrays to multiplication facts. They will also shade them on graph paper. Next, students practice skip-counting the multiples of 3. This is followed by more fact practice. Students are then encouraged to build on what they know by using times 2 facts. For example, for 2 × 6 = 12, add one more group of 6 for 3 × 6 = 18. Students also review the commutative property as they complete another practice exercise.
Quiz
Students respond to ten multiple-choice and true/false questions.
Closing
Students will create story problems with answers that are multiples of 3. They will share these with a classmate.
Instruction materials
To complete the story problem project, you will need:
- Construction paper
- something to color with
