The purpose of the foundations is to promote understanding of preschool children’s learning and to guide instructional practice.

The Foundations…are for all children, including children learning English and children with disabilities. They describe the knowledge and skills that young children typically exhibit:
– at around 48 and 60 months of age;
– as they complete their first or second year of preschool;
– with appropriate support; and
– when attending a high-quality preschool program.

High-Quality Programs Include
– environments and experiences that encourage active, playful exploration and experimentation
– purposeful teaching to help children gain knowledge and skills
– specific support for children learning English
– specific accommodations and adaptations for children with special needs

Strand - Substrand Order
• There is a developmental progression from three- to four-years-old within a substrand.
• The order in which the strands and substrands are presented is not meant to indicate a developmental progression.

Young Children and Shape:Two Studies
• Hundreds of children, 3 to 6 years old
• First study used same tasks as used in previous research with older students
![Page 30: 1 How Can Administrators Support Staffs Understanding of Geometry?](https://reader030.vdocuments.mx/reader030/viewer/2022013011/5515511555034673228b64ac/html5/thumbnails/30.jpg)

CirclesCorrectness
• 92% - 4 year olds
• 96% - 5 year olds
• 99% - 6 year olds
• Few youngest chose ellipse and
curved shape
• Described as “round”
• Thus, easily recognized but
difficult to describe
• Matched shapes to visual prototype

Squares• Only slightly less
accurate in identifying squares:82%, 86%, and 91%
• Youngest lower on nonsquare rhombi but not on “tilted squares”
• Minority reasoned about properties, but was relationship between such responses and correct selections

Geometry Must Move Beyond “Basic” Shape Naming to:
• Parts & Properties
– Shape attributes
– Include analysis and description
• Mental images and transformations
• Composing and decomposing

Let’s Play
• Use the materials on your table and the direction card to play the game.
• You have 20 minutes to play the game and to identify what foundations the game addresses and what kind of documentation you might gather to demonstrate children’s growth and development.
• Share your game with the group.

Division of Early ChildhoodPractices are individualized for each child based on:
• child’s current behavior and abilities across relevant domains instead of the child’s diagnostic classification
• the demands, expectations, and requirements of the child’s current environment
• team planning that incorporates the input of family and various providers
• staff knowledge of validated strategies including prompting and fading procedures to ensure acquisition of skills
• IEP consideration and/or requirements

Physical space and materials are structured and adapted to promote engagement, play, interaction, and learning by attending to children’s preferences, interests, using novelty, responsive toys, providing adequate amounts of materials and using defined spaces.

• What does it say about children with disabilities?

Geometry Foundations and Children with Disabilities
Children may need:• assistance to manipulate objects• adaptive materials that are easy to grasp• to demonstrate knowledge in alternative ways without
directly manipulating objects• clearly defined work space• materials that are easily distinguishable by touch

Walk and Talk
• Misconception: Math is about numbers, therefore, understanding the language of instruction isn’t so crucial.
• Reality: Math is abstract in nature and requires specific vocabulary to talk about it!
![Page 59: 1 How Can Administrators Support Staffs Understanding of Geometry?](https://reader030.vdocuments.mx/reader030/viewer/2022013011/5515511555034673228b64ac/html5/thumbnails/59.jpg)

Through using language creatively and interactively, children develop the thinking necessary to communicate mathematically to solve real problems with their everyday experience.

60
Scaffolding as a Strategy
When children are given opportunities to build on their existing knowledge base, words in their new language are more easily mastered because they are linked to familiar concepts.
![Page 61: 1 How Can Administrators Support Staffs Understanding of Geometry?](https://reader030.vdocuments.mx/reader030/viewer/2022013011/5515511555034673228b64ac/html5/thumbnails/61.jpg)
61
Minor Adjustments
• Check for understanding.
• It is more than eye contact.
• Use of primary language, use of icon, use of actual object.
• Use follow-up questions.

Bringing it Back to the Classroom• Share information from today’s session. Include the research and the
importance of Geometry.
• Provide some of the resources shared today and give teachers time to read and discuss the information.
• Host a math make and take workshop providing all the materials and time needed for teachers to make games.
• Focus on making small changes guided by a consistent, coherent, grand vision.
• Allow teachers to learn and reflect on new approaches, implement them, and discuss.
• Provide teachers with high-quality mathematics references and classroom materials.

Topics for Discussion• How does this fit with our current experience and knowledge?
• What are the barriers to implementation?
• What more do we need (geometry materials, model strategies)?
• What are realistic expectations for Geometry content for providers?
• Are there special considerations for English-learners?
• How does this information impact children’s IEP goals?

Geometry in the World
Pat H.’s preschool was studying
bees.
Children noticed the hexagon.
T: Why do you think they
chose?
C1: It popped in their heads.
C2: They found one under a
tree.
Let’s see some of the others…
