Richard Skemp was a mathematician who
many years ago published an important
discussion paper regarding math. The gist of
it was that it was that for deep
understanding, both rules and reasons are
important; but reasons should come before
rules. The relational understanding must be
before the instrumental understanding.
Developing Early Number Sense
Rote counting
 Rational counting
 Cardinal numbers
 Subitizing
 Ordinal numbers
 Measurement
 Nominal numbers

Developing Early Number Sense
Rote counting Includes: NWA, NWB, skip counting
 Rational counting Leads to 1:1 correspondence

with and without touch
Cardinal numbers
 Subitizing
group to tell how many without counting
 Ordinal numbers
 Measurement
 Nominal numbers
address, phone number, etc.

Look and Talks
What is a look and talk?
 Five Little Monkeys Wash the Car
 Big Books- Kindergarten Math in Focus

◦ Use the questions from Math in Focus teacher
resource book
“Math Talk” resource
 Singaporemath.com

◦ Search: Big books- teach math through
nursery rhymes
Number Bonds (Part-Part Whole)

For a deep understanding…
◦ Multiple models
◦ Varied purposeful practice
“The Story of 4” example
 Triangle fact families
