Starting at a given number, count forward and backwards within 120 by ones. Skip count by 2s to 20 and by 5s to 100.


Clarifications


Clarification 1: Instruction focuses on the connection to addition as “counting on” and subtraction as “counting back”. 
Clarification 2:Instruction also focuses on the recognition of patterns within skip counting which helps build a foundation for multiplication in later grades.

Clarification 3: Instruction includes recognizing counting sequences using visual charts, such as a 120 chart, to emphasize base 10 place value.

Purpose and Instructional Strategies

The purpose of this benchmark is for students to interact with patterns found in counting. In Kindergarten, students recited number names to 100, counted forwards within 100 and backwards within 20. In Kindergarten, students also built the understanding that successive numbers refer to quantities one larger, and built the foundation for addition and subtraction (MTR.5.1).
  • Instruction builds the foundation for strategies of addition and subtraction through counting forwards and backwards (MTR.5.1). 
  • Instruction includes skip counting within this benchmark which builds to repeated addition, the basis for multiplication (MTR 3.1).

 

Common Misconceptions or Errors

  • Students may omit numbers when counting in a sequence.
  • Students may not understand how to use visual charts to answer questions.

 

Strategies to Support Tiered Instruction

  • Instruction includes the use of a bottoms-up hundreds chart. Using the chart, the teacher asks students to find a number, like 8. Once they point or identify the number, students count forward by one until they reach 25. Student should locate and identify each number on the chart as they count. 
    • For example, the teacher asks the student what happens when they come to the number 10? 20? What do they notice? Repeat this activity counting backward starting at 57 and have them count by one until they reach 35. 

  • Instruction includes the use of a bottoms-up hundreds chart. Students identify specified numbers on the chart and understand that values increase as they move to the right and up on the chart, as well as decreasing or counting backward would require tracking left and down. Students may need additional instruction once they reach the end of a row, they start back on the left as they count up or back on the right as they count down.

 

Instructional Tasks

Instructional Task 1 (MTR.1.1, MTR. 3.1, MTR.5.1, MTR.6.1

  • Part A. In a small group, present students with the portion of the 120 chart below. Use the questions to facilitate discussion. Allow students time to independently think then share with the group. Encourage students to justify their thinking. 
  • Part B. Provide students with a blank hundred-twenty chart and a highlighter and ask them to complete Emma’s pattern, as shown below. 

  1. What pattern do you notice? 
  2. Should any other numbers be shaded on her chart? 
  3. What other numbers do you think she could shade on a 120 chart? 
  4. If Emma continues the pattern, would 75 be shaded or not shaded? 

 

Instructional Task 2 (MTR.7.1

  • Jeremiah and Michael are going to the store with these coins in their pocket. What is the total value of the coins?

Students use a counting strategy to find the difference between two numbers.

Counting Backward

Students are asked to count backward by ones, first from 10, and then from larger numbers within 1000. 

Using Counting On Strategies

Students are encouraged to use Counting On to solve Add To (Result Unknown) word problems.

How Many Fish?

Students read three-digit numbers aloud, write three-digit numbers they hear the teacher say, count 116 fish on a page, and write the number of fish corresponding to their count.

Addition and Subtraction Equations

Students are asked to write equations that correspond to counting strategies used in word problems.

Beads On A Necklace

Students are guided to use counting to find the sum of two numbers.

Students will make a personalized calendar of patriotic holidays to reference throughout the academic or full calendar year. 

Guess Who: True American Edition

In this integrated lesson plan, students will identify US coins, express their values using the cents (¢) symbol and state their equivalency to the US dollar while recognizing symbols and individuals that represent the United States.

Counting Coral Reef Babies

Students will listen to the book Over in the Ocean in a Coral Reef, by Marianne Berkes. They will participate in an inquiry to figure out how many baby animals are in the book. They will show the number of animals in the book in groups of ten and some left over. This lesson is a beginning place value and addition lesson for first grade. 

Best Babysitter

Teams of students will use math to solve an open-ended, real-world problem to help their parent or caregiver choose the best babysitter. Students will apply mathematical skills of place value (two-digit number tens and ones) and counting to perform math calculations while analyzing data sets. This MEA will facilitate students demonstrating higher level critical thinking and problem solving during class discussions and in writing.

No Kidding Hurricane Kit

Children are challenged to create hurricane kits from a list of $5 supplies and a fixed budget. In a twist, students are asked to revise their kits to account for diverse families including families with young children, families with elderly adults, and families with pets. They are given an increased budget and a checklist for each type of kit.  The expectation is that students can determine which supplies would be useful in an emergency hurricane kit and that they can skip-count by 5’s to make sure they stay within their budgets.

Problem-Solving Tasks

Name Description
Counting Circles II

This activity is designed to target trouble spots that children have with counting so it is important to keep the sequence short and focused. If the majority of the class is struggling with the getting past 30 into the next family, or the "teen" numbers, or crossing the century from 99 to 100 this activity can be used to target a specific area and then move on to the next trouble spot. This activity is also effective for skip counting sequences.

Choral Counting II

The purpose of this task is for students to practice counting in a variety of ways.

“Crossing the Decade” Concentration

The purpose of this task is to help students learn the number sequence. One of the most common areas that young children struggle with when learning to count forward is crossing from one family to the next, for example getting to 29 in the counting sequence and not knowing what comes next or stating a random decade number. This game supports student development in this area.

Where Do I Go?

This activity is designed to be a short, repeatable activity to build student flexibility with the number sequence. Begin by randomly giving each student in the classroom one card from one of the sets you have made. Challenge the students to get themselves into order as quickly as they can.

Start/Stop Counting II

The idea is not for the student to figure out the counting sequence but to hear it and practice it repeatedly in a facile manner. It is important to keep the counting moving quickly and smoothly so offering support to the students from the teacher by giving the number name to a student if they are struggling or having the whole group count with them until they can be independent is appropriate.
