Unit: Math – Multiplication Foundations
Day 2: Equal Groups to Equations
Materials:
Counters (chips, cubes, etc.)
Whiteboards
Markers
Standards:
CCSS.MATH.CONTENT.3.OA.A.1
Interpret products of whole numbers
Introduction (5 minutes):
Review equal groups from Day 1
Ask students: “How can we show these groups as numbers?”
Direct Instruction (10 min):
Model writing repeated addition and multiplication equations
from equal groups
Example: Show 3 groups of 2: repeated addition 2 + 2 + 2 = 6,
multiplication 3 × 2 = 6
Guided Practice (10 min):
Students build groups with manipulatives and write both
repeated addition and multiplication equations
Ask: “How many groups?” “How many in each group?”
Activity (10 min):
Students match pictures of equal groups to the correct
repeated addition and multiplication equation or Students build
groups and write both equations with a partner
Closing:
Review: “Repeated addition and multiplication are two ways to
show equal groups.”
