Module 5
Numbers 10-20; Count to 100 by Ones and Tens


 
Overview

Throughout this module students will:
  • Count to 100 by ones and by tens
  • Count forward beginning from a given number within the known sequence (instead of having to begin at 1)
  • Write numbers from 0 to 20.  Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects)
  • Count to answer "how many?" questions
  • Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones
