This Illuminations lesson is the third of an eight-part unit titled “Begin With Buttons.” In this lesson, students review classification, make sets of a given number, explore relationships between numbers, and find numbers that are one more and one less than a given number. They apply their knowledge of classification as they play a game similar to bingo.

This lesson is referenced in the Illuminations unit plan titled “Begin with Buttons” and is related to the Illuminations lessons titled “Button Trains,” “Many Sets of Buttons,” “How Many Buttons?,” “More and More Buttons,” “Numbers Many Ways,” “Lost Buttons,” “Shirts Full of Buttons,” and “Begin with Buttons: Looking Back and Moving Forward.”

Mathematics (2004)

Grade 1

  • Goal 1: Number and Operations - The learner will read, write, and model whole numbers through 99 and compute with whole numbers.
    • Objective 1.01: Develop number sense for whole numbers through 99.
      • Connect the model, number word, and number using a variety of representations.
      • Use efficient strategies to count the number of objects in a set.
      • Read and write numbers.
      • Compare and order sets and numbers.
      • Build understanding of place value (ones, tens).
      • Estimate quantities fewer than or equal to 100.
      • Recognize equivalence in sets and numbers 1-99.
  • Goal 5: Algebra - The learner will demonstrate an understanding of classification and patterning.
    • Objective 5.01: Sort and classify objects by two attributes.
    • Objective 5.02: Use Venn diagrams to illustrate similarities and differences in two sets.

Kindergarten

  • Goal 1: Number and Operations - The learner will recognize, model, and write whole numbers through 30.
    • Objective 1.01: Develop number sense for whole numbers through 30.
      • Connect model, number word (orally), and number, using a variety of representations.
      • Count objects in a set.
      • Read and write numerals.
      • Compare and order sets and numbers.
      • Use ordinals (1st-10th).
      • Estimate quantities fewer than or equal to 10.
      • Recognize equivalence in sets and numbers 1-10.
  • Goal 2: Measurement - The learner will explore concepts of measurement.
    • Objective 2.01: Compare attributes of two objects using appropriate vocabulary (color, weight, height, width, length, texture).
  • Goal 5: Algebra - The learner will model simple patterns and sort objects.
