Common Core State Standards

CCSS.MATH.CONTENT.3.OA.A.3
Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities.

CCSS.MATH.CONTENT.3.OA.C.7
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division or properties of operations.

CCSS.MATH.PRACTICE.MP1
Make sense of problems and persevere in solving them.

CCSS.MATH.PRACTICE.MP4
Model with mathematics.

Learning Objectives

I can use multiplication to compare two quantities.
I can explain how multiplication helps me find which group is larger and by how much.
I can solve word problems that use multiplication to compare.
I can demonstrate understanding by completing a worksheet independently or with support.

Success Criteria

Students can correctly solve multiplication problems comparing two groups.
Students can explain why one quantity is greater than another using multiplication.
Students show the ability to work on problems without giving up (MP1).
Students use drawings or arrays to model the math problems (MP4).

Materials

Dry erase boards and markers (for quick work and visual practice)
Multiplication comparison worksheet (custom made, see below)
Visual aids: arrays and images showing groups (dots, stars)
Dyslexia-friendly colored overlays and large print worksheet version
Timers (for pacing discussions and worksheet segments)

Lesson Plan

1. Introduction & Engagement (5 minutes)

Warm-up: Ask students to think about two groups of objects (e.g., 4 baskets with 5 apples each vs. 3 baskets with 7 apples each).
Pose the question: "Which group has more apples? How do you know?"
Facilitate a brief class discussion, encouraging students to think about repeated addition and multiplication.
Introduce the concept: "We can use multiplication to compare groups quickly instead of counting one by one."

Differentiation: Provide a hands-on example with physical counters for students who need concrete visual support. Use dyslexia-friendly fonts and colours on boards.

2. Explicit Teaching & Modelling (8 minutes)

Demonstrate how to write and solve multiplication sentences to compare two quantities. Example:
- Group A: 4 baskets × 5 apples = 20 apples
- Group B: 3 baskets × 7 apples = 21 apples
Show how comparing 20 and 21 answers which is larger and by how much.
Model using arrays on the board to visualize groups and quantities.

Differentiation:

For advanced learners: Challenge them to create word problems with larger numbers or to explain using multiplication properties (commutative).
For struggling learners: Use smaller numbers and more visual support (dots, stickers).

3. Guided Practice (7 minutes)

Distribute the worksheet (see below).
Work through the first 2 problems together as a class using multiplication to compare.
Encourage students to draw pictures or arrays if it helps them.
Walk around to provide support and reassurance.

4. Independent/Pair Work (7 minutes)

Students complete the remaining problems on the worksheet individually or in pairs.
Use dyslexia-friendly overlays and large print as needed.
Provide encouragement to use "I can" statements aloud as they work.

5. Review and Reflect (3 minutes)

Ask students to share one problem they liked or found easy.
Have them explain how they used multiplication to find which group was bigger or how much bigger it was.
Reinforce success criteria and "I can" statements.

6. Extension Activity (For Advanced Learners)

Create your own word problems comparing two groups using multiplication with numbers beyond 10.
Illustrate with arrays or repeated addition and explain your thinking to a partner or the class.

7. Differentiation Strategies

Learner Type	Supports
Dyslexic learners	Dyslexia-friendly fonts and overlays, large print worksheets, multisensory approach (counters, drawings)
Visual learners	Use of arrays and visual grouping aids
Struggling learners	Smaller numbers, extra modeling, scaffolding questions
Advanced learners	Extension problems, creating own word problems, explanation focus

Multiplication Comparison Worksheet

Name:___________________ Date:_____________

Instructions: Use multiplication to compare the two groups. Write a multiplication sentence for each group. Circle the group that has more objects and explain how you know.

Example:

Group A: 5 boxes with 4 toys each
Group B: 4 boxes with 5 toys each

5 x 4 = 20 toys
4 x 5 = 20 toys
They have the same number of toys!

Group A: 3 bags with 6 marbles each
Group B: 4 bags with 5 marbles each
Group A: 7 baskets with 2 oranges each
Group B: 5 baskets with 3 oranges each
Group A: 6 packs with 4 crayons each
Group B: 3 packs with 8 crayons each
Group A: 2 trays with 9 cookies each
Group B: 3 trays with 5 cookies each

Bonus: Write your own problem and solve it using multiplication.

This lesson plan promotes engagement with multiplication through comparison, uses visual supports and flexible learning options for diverse needs, and aligns fully with 3rd grade Common Core standards to master problem-solving and fluency in multiplication.
