The Question
A problem well stated is a problem half solved.
-John Dewey
How do we develop a tool that will both identify students who
are struggling in early numeracy skills, and tell us where to
begin instruction?

Stages of Early Arithmetical Development
(Early Numeracy Assessment for Teaching and Intervention, Wright, Martland, Stafford, 2001)
“Progression across the stages involves the child using
counting in increasingly sophisticated ways to solve additive
and subtractive tasks.”
Similar to Catherine Fosnot’s “Learning Landscape”.
“Stages provide the means of understanding the progression
of children’s early number learning from perceptual counting
strategies to sophisticated knowledge of addition and
subtraction in the range from 1 to 100 and beyond.”

What’s on the Horizon?
Solve the following equation:
371 -169 =
Turn and talk with the person next to you to explain how you
solved it.

What’s on the Horizon?
371 -169 =202
Here is how one third grader solved this problem in his head:
First I took the 300 and subtracted the 100 and got 200. Then I
knew that 71 was really close to 69; so I counted up from 69 to 71
and got 2. I added the 200 and the 2 and got 202.
371-169 = (300 +71) - (100+69)= (300-100) + (71-69)

Number Knowledge:
Computational Strategies
•Able to say/read number.
•Use nested numbers to
decompose and compose.
•Able to cross decades fluently.
•Able to see nested numbers.
•Able to use distributed
property.
•Understands Base Ten System.

S.E.A.L.
Stages of Early Arithmetical Learning
STAGE 0 - Pre-perceptual or Emergent Counting
Cannot count visible items
Does not know the number words or cannot coordinate the
number words with items
STAGE 1 – Perceptual Counting
Can count visible items, but not those in screened collections
Can match the number words with the items
May involve seeing, hearing or feeling items
STAGE 2 – Figurative Counting
Can count the items in screened collections
Starts counting from one to count items (repetitive
counting)

S.E.A.L.
Stages of Early Arithmetical Learning
STAGE 3 – Initial Number Sequence or Counting on
Uses counting-on rather than counting from “one” to solve
addition problems
Uses count-down-from strategy, NOT count-down-to
STAGE 4 – Intermediate Number Sequence
Uses count-down-to
Chooses more efficient strategy of count-down-from and
count-down-to
STAGE 5 – Facile Number Sequence
Uses a range of non-count-by-one strategies
Sees a number within another number in an explicit sense

Looking at the Data:
• What does it tell us about the class?
• What does it tell us about the individuals?
• What questions do you still have about the
class and/or individuals?
