Today’s Agenda

Research- Progression of Mathematical

Reasoning

KY Academic Standards that build the

sequences of multiples

Foundation of Number Word Sequences

SLIDE 5

Progression of Mathematical Reasoning

SLIDE 6

Development of Reasoning

SLIDE 7

Standards

KY.2.NBT.2~ Forward/Backward Number Sequences ➔ Count forwards and backwards within 1000; skip-count by 5s, 10s, and 100s. KY.3.OA.9~ Identify Arithmetic Patterns

SLIDE 8

Number Word Sequences

Learning number word sequences should continue beyond 1st grade. Students need to learn:

NWS of decuples, centuples, and 1000s
NWS by 2s, 3s, 4s, etc, which become

central to developing strategies for multiplication and division

SLIDE 9

Verbal Aspect is Important

SLIDE 10

Just Do It! Don’t Skip Skip-counting!

As students come to know basic facts in any

peration, they progress through three

phases (Baroody, 2006):

Phase 1: Counting
Phase 2: Deriving
Phase 3: Mastery
