  1. Out with the Old… First Grade Mathematics

  2. Out with the Old… • Estimation • • Groupings of 2’s, 5’s, and 10’s to count collections • • Fair Shares • • Specified types of data displays • • Certain, impossible, more likely or less likely to occur • • Venn Diagrams • • Extending patterns There are about 15 cookies in the jar.

  3. In with the New! • Comparison Symbols (<, >) • Defining and non-defining attributes of shapes • Half-circles, quarter-circles, cubes • Partitioning circles and squares; Relationships among halves, fourths and quarters • Use of a symbol for the unknown number in an equation • Properties of Operations – Commutative and Associative • Counting sequence to 120; writing numerals to 120 • Unitizing a ten (10 can be thought of as a bundle of ten ones, called a “ten”)

  4. Use of a symbol for the unknown number in an equation 4 + 5 + 6 =

  5. Properties of Operations – Commutative and Associative

  6. Counting sequence to 120; writing numerals to 120 56, 57, 58, 59, 60, 61

  7. Unitizing a ten (10 can be thought of as a bundle of ten ones, called a “ten”)

  8. Comparison Symbols (<, >) Compare these two numbers. 42 __ 45 greater than (>) less than (<) equal to (=)

  9. Defining and non-defining attributes of shapes Defining Attribute: This shape is a triangle because it has three sides that are closed. Non-Defining Attribute: This shape is a green and tall.

  10. Partitioning circles and squares; Relationships among halves, fourths and quarters
