Costas’ Method
Intellectual Functioning
Level 1 - focus on Gathering and recalling
– Level 2- focus on Processing and making sense of gathered information
– Level 3 - focus on Applying and evaluating information
The Eight Mathematical Practices
1. Make sense of problems & persevere in solving them.
2. Reason abstractly and quantitatively.
3. Construct viable arguments & critique others reasoning.
4. Model with mathematics.
5. Use appropriate tools strategically.
6. Attend to precision.
7. Look for and make use of structure.
8. Look for and express regularity in repeated reasoning.
The Octa-Habits

Multiple Models & Varied Practice/Experiences
(Zoltan Dienes)
Foundations of Number Sense C-P-A
Instructional strategies build understanding
through activities that move students in a
sequence from the Concrete (manipulatives) to
the Pictorial (visual models) and finally to the
Abstract (symbolic) level. - Bruner-
Counting Change
A student wanted to buy a $1 soda at a vending machine, but did not have the correct change. What is the greatest amount of change he could have and still not be able to make the exact change for the purchase?
Counting Change
Reasoning and Proof
Even wrong answers have reasons behind them
Communication
Being precise means that we understand that
coins and change are two different things. The
problem is not asking about coins, but change.
Foundations of Number Sense Perceptual Variability
Conceptual learning is maximized when
children are exposed to a concept through a
variety of physical contexts. Using a variety of
materials and experiences leads to an
understanding of mathematical abstraction.
Short, varied practice on a regular basis.
Perceptual Variability

Place value disks

and how).

Properties
CCSS K-8 math standards mention properties 66 times.
Properties are ways that numbers and operations
interact with one another.
Traditionally, these have been taught to students by
learning the definitions – this is changing!
Students need to be USING the properties in order to
appreciate them.
Using properties in math allows for flexible thinking,
which is linked to proficiency.
Number Talk General Goals
Increased discourse among students
Greater conceptual learning
Greater problem solving skills
Number Talk Progressive Goals
Goal: Improve computational fluency by
encouraging students to:
Use any strategy that makes sense to them
Then to be able to use more efficient strategies
that they have learned from their peers
And to finally progress to “just knowing it” or
using most efficient strategies for computation
Achieving Mathematical Discourse
1. Increase opportunities for students to question, explore, and challenge each other’s thinking
2. Discuss relationships between numbers and operations
3. Discuss many different strategies for solving different problems
