Engaging First Grade Mathematics: From Basics to New Concepts

This resource focuses on essential first-grade mathematics concepts, transitioning from traditional methods to modern techniques. Topics include estimation, grouping, fair shares, and data displays, while introducing new elements like comparison symbols, shape attributes, and the relationship of fractions. Students will explore patterns, counting sequences up to 120, and operations properties through hands-on activities like unitizing and using symbols for unknown values. Designed for comprehensive understanding and practical application in the classroom.

Presentation Transcript

  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
