Strand: NUMBER AND OPERATIONS IN BASE TEN (1.NBT)

Extend the counting sequence (Standard 1). Understand place value (Standards 2–3). Use place value understanding and properties of operations to add and subtract (Standards 4–6).

Standard 1.NBT.1

Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.

• "Crossing the Decade" Concentration
This game is a version of the traditional memory or concentration game. Students will us a set of number cards for each of the pair of numbers that cross the decade, i.e., 19 and 20, 29 and 30, 39 and 40, 49 and 50, etc. Students place all the number cards that end with 9 face down in an 3x3 array on the left and all the number cards that end with 0 face down in a 3x3 array on the right. Working in pairs or trios, students take turns. The first student selects a card from the left array, stating the number name and the counting number that follows ("I have 39, I need 40"). When a student finds a matching pair he or she keeps that pair of cards. Play continues until all cards have been matched. The student with the most matched pairs wins.
• Choral Counting II
In this activity students work with a large number line and chant a counting sequence when led by the teacher using a pointer.
• Grade 1 Math Module 6: Place Value, Comparison, Addition and Subtraction to 100 (EngageNY)
In this final module of the Grade 1 curriculum, students bring together their learning from Module 1 through Module 5 to learn the most challenging Grade 1 standards and celebrate their progress. As the module opens, students grapple with comparative word problem types. Next, they extend their understanding of and skill with tens and ones to numbers to 100. Students also extend their learning from Module 4 to the numbers to 100 to add and subtract. At the start of the second half of Module 6, students are introduced to nickels and quarters, having already used pennies and dimes in the context of their work with numbers to 40 in Module 4. Students use their knowledge of tens and ones to explore decompositions of the values of coins. The module concludes with fun fluency festivities to celebrate a year's worth of learning.
• Grade 1 Mathematics Module 4: Place Value, Comparison, Addition and Subtraction to 40 (EngageNY)
Module 4 builds upon Module 2's work with place value within 20, now focusing on the role of place value in the addition and subtraction of numbers to 40. Students study, organize, and manipulate numbers within 40. They compare quantities and begin using the symbols for greater than (>) and less than (<). Addition and subtraction of tens is another focus of this module as is the use of familiar strategies to add two-digit and single-digit numbers within 40. Near the end of the module, the focus moves to new ways to represent larger quantities and adding like place value units as students add two-digit numbers.
• Hundred Chart Digit Game
This task is a bingo-like card game where students draw numbers and then mark the spaces on their card for both numbers that can be made with those digits.
• Number of the Day
This activity provides a connection between the counting sequence and an experience from students' daily lives. It helps to give the students a sense of how "many" each number is.
• Start/Stop Counting II
This activity has the teacher walking around the room while counting aloud from a number between 1 and 20. The teacher continues to count until he/she chooses a student by patting them on the shoulder. The student and teacher switch roles, the teacher sits in the studentâ€™s chair while the student resumes the count and walks around the room. At the teacherâ€™s signal the student selects the nearest student and switches places with another child who continues the count. Repeat this until each child has had a turn counting.
• USBE Core Guide for Domain: Number and Operations in Base Ten (1NBT1)
This math guide provides academic vocabulary, instructional strategies, teacher resources, and assessment tasks for the Number and Operations in Base Ten domain.
• Where Do I Go?
This activity involves a card game and is designed to be a short, repeatable activity to build student flexibility with the number sequence.
