Unit: 1 Renzoni
Domain: Operations and Algebraic Thinking
Week: 7
Day: 1 Monday 9-26-16
Suggested time/duration: 60 minutes
Standard: MAFS.2.OA.3.3
Determine whether a group of objects (up to 20) has an
odd or even number of members, e.g., by pairing
objects or counting them by 2s; write an equation to
express an even number as a sum of two equal
addends.
Learning Target(s):
Rigor: Procedural Skill and Fluency

show and explain how to pair manipulatives to demonstrate odd and even
numbers
 show and explain how an even number can be separated into two equal
groups (without altering one of the objects) while an odd number cannot be
separated into two equal groups.
 write an equation to express an even number as a sum of two equal
addends, also known as doubles
 identify numbers as odd or even and explain why.
SMP(s): 4. Model with mathematics 7. Look for and make use of structure 8. Look
for and express regularity in repeated reasoning
