First Grade Unit 1: Counting and Numbers

Unit 1 - Counting and Numbers

Content Emphasis/ Big Ideas

In this unit, students count objects and write numerals up to 100. Students also explore counting backward from 30 and reason about the magnitude of one- and two-digit quantities. While working on these counting skills, students are asked to describe the patterns they notice in our number system.

Standards:

Count forward orally by ones to 100, starting at any number between 0 and 100
Write the numerals 0 to 100 in sequence and out-of-sequence
Count backward orally by ones from 30
Count forward orally by ones, fives, and tens to determine the total number of objects to 100
Given up to 100 objects, compare two numbers between 0 and 100 represented pictorially or with concrete objects, using the words greater than, less than or equal to
Given up to 100 objects, order three or fewer sets from least to greatest and greatest to least
Given an ordered set of ten objects and/or pictures, will indicate the ordinal position of each object, first through tenth
Given a familiar problem situation involving magnitude, select a reasonable order of magnitude from two given quantities: a one-digit numeral and a two-digit numeral (e.g., 5, 50)
Given a familiar problem situation involving magnitude explain the reasonableness of the choice
Identify, describe, extend, create and transfer growing and repeating patterns
