Foundations for Success

“Most children acquire considerable knowledge of…mathematics before … kindergarten.

…related to their mathematics learning for years thereafter - even high school.”

5

Young children can learn amazingly broad, complex, and sophisticated mathematics.

Surprise #2: Children’s Math Potential

Preschool Potential

Finishing, Cory shows adult, who asks:“How many triangles did you use?”

Cory counts: “24”

“24 what?”

“Triangles.”

“How many squaresdo you have?”

• Yes, you can! 8 from 4 is negative four 64 -28 -4

• “…and 20 from 60 is forty: 64 -28 -4 40

• …and negative four and 40 is 36” 64 -28 -4 40 36

“In the curriculum, a view of all children as having the capacity to engage with deep and challenging mathematical ideas and processes from birth should be presented.”

“Mathematics is viewed not only as useful and as a way of thinking, seeing and organising the world, but also as aesthetic and worthy of pursuit in its own right (Zevenbergen, Dole, & Wright, 2004).

All children are viewed as having an ability to solve mathematical problems, make sense of the world using mathematics, and communicate their mathematical thinking.”

Surprise #3: Surprise to Educators

• What young children can learn is a surprise to most early/primary educators.

• Therefore, they do not challenge children or use formative assessment effectively (especially “ends”).

Not Just the Poor

Equity

• Especially low-income children who hear about 1,500 number words a year

• Compare to middle-income: 93,000

• Middle hear 60 times as many words!

Small Numbers and Counting

• Finger plays:

• One, two, buckle…

• When I was one…When I was one, I was so small, (hold up 1 finger)

I could not speak a word at all. (shake head)

When I was two, I learned to talk. (hold up 2 fingers)

I learned to sing, I learned to walk. (point to mouth and feet)

When I was three, I grew and grew. (hold up 3 fingers)

Now I am four and so are you! (hold up 4 fingers)

• Later: Five Little Monkeys, etc.

“Of the assessment approaches available, formative assessment offers most promise for generating a rich picture of young children’s

mathematical learning (e.g., NCCA, 2009b; Carr & Lee, 2012).

Strong conceptual frameworks are important for supporting teachers’ formative assessments

(Carr & Lee, 2012; Ginsburg, 2009a; Sarama & Clements, 2009). ”

Math, Literacy, and Play

• Curricula focus lead to stronger emphasis in subject-matter

• Children in content-focused classrooms more likely to engage at high-quality level during free play

• Those focusing on both math and literacy more engaged at high level than neither or only one!

47

Play with Ideas

• Regular play with blocks, puzzles, socio-dramatic play (with self-regulation), and

• Enhancement of math in that play, and

• Intentional, planned, math (LTs)...and

• Play with mathematics
