Foundational Math Strategies Fall 2014

Objectives  I can understand the math CRA approach.  I can use concrete and representational strategies to teach number knowledge.

Table Talk  What math skills do students lack most?  Share out  The ability to compose and decompose numbers fluently.  Basic facts: Teaching math without basic facts is like trying to read only knowing 20/26 letters.

Foundational Skills Three key areas that must be in place: 1. Conceptual understanding 2. Number sense 3. Accurate computation

C-R-A Approach

Number Knowledge  Number knowledge builds number sense.  The more we investigate numbers the better we understand math and how to teach it.  One strategy we can do to help with students’ understanding of number knowledge is to start each math lesson with a number knowledge exploration.

Number Knowledge  Show eight ways to represent the number 18  Show eight ways to represent the number 1

Flow Map

Number ID, Counting, and Comparing and Ordering Concrete  Tens bracelet  Number line  Ziploc bags  Unifix cubes  Base ten blocks Representational  Number line  Hundreds charts

Place Value  Create human place value chart  Concretely represent the value of each place with base ten blocks  Show the relationship between each place (ten times the next place)

Addition and Subtraction Concrete  Base ten blocks  Unifix cubes Representational  Number line  Decomposing

Multiplication and Division  Concrete- use base ten blocks to multiply  Decompose numbers (distributive property)  Fearsome fifteen
