Counting & Place Value:

Page 1: Counting Forward and Backward Activity: Count Forward & Backward

Write numbers from 1 to 100 in order. Then, list numbers backward from 100 to 1. Challenge: Fill in missing numbers in a counting sequence. Page 2: Counting Forward in Tens Activity: Skip Counting by 10s

Complete the sequence counting by 10s starting from 10 to 100. Fill in missing numbers in a skip-counting sequence. Page 3: Counting Backward in Tens Activity: Skip Counting Backward by 10s

Start from 100 and count backward by 10s to 10. Fill in missing numbers in a backward skip-counting sequence. Page 4: Count Forward from a Given Number Activity: Counting from Any Number

Start counting from a number between 30 and 90. Count forward by ones to reach 100. Write the next five numbers. Page 5: Count Backward from a Given Number Activity: Counting Backward from Any Number

Start counting backward from any number between 50 and 100. Write the next five numbers backward. Page 6: Identifying Tens and Ones Activity: Place Value Breakdown

Given numbers (e.g., 56), break them into tens and ones (e.g., 50 + 6). Match the number with its correct tens and ones. Page 7: Number Blocks for Place Value Activity: Tens and Ones Blocks

Use number blocks to build numbers up to 99. Write the number in standard form, expanded form, and place value form. Page 8: Write Numbers in Expanded Form Activity: Expanded Form Challenge

Write numbers in expanded form (e.g., 45 = 40 + 5). Given numbers, students will split them into tens and ones. Page 9: Place Value Fun with Coins Activity: Using Coins to Represent Numbers

Use pennies (1), dimes (10), and quarters (25) to show numbers up to 100. Write the numbers in expanded form based on the coins. Page 10: Fill in the Place Value Chart Activity: Place Value Chart

Fill in a chart showing the number of tens and ones for numbers up to 99. Write the number in both standard and expanded form. Page 11: Matching Expanded Form Activity: Match the Number to its Expanded Form

Given a list of numbers, match them to their correct expanded form (e.g., 72 → 70 + 2). Page 12: Place Value Word Problems Activity: Solving Place Value Problems

Solve word problems involving identifying tens and ones in numbers (e.g., "You have 23 marbles. How many tens and ones do you have?"). Page 13: Tens and Ones Sorting Game Activity: Sorting Game

Sort numbers into “tens” and “ones” categories. For example, 53 goes in the tens box (50) and ones box (3). Page 14: Number Comparison Activity: Compare Numbers Using Place Value

Given two numbers (e.g., 45 and 54), determine which one is greater based on tens and ones. Page 15: Expanded Form with Addition Activity: Adding in Expanded Form

Break down numbers into expanded form and add them. Example: 30 + 12 = (30 + 2) + (10) = 42. Page 16: Counting in Groups of Ten Activity: Count in Groups

Count items in groups of 10, then identify the number of tens and ones. Page 17: Number Fill-in-the-Blanks Activity: Place Value Fill-in

Given a number (e.g., 67), fill in blanks for tens and ones. Page 18: Tens and Ones Coloring Activity Activity: Color the Correct Number of Tens and Ones

Color ten groups of ones or ten groups of tens to represent different numbers. Page 19: Place Value Riddles Activity: Solve the Riddle

Solve fun riddles about tens and ones (e.g., "I am 54, but my tens are 50. What am I?"). Page 20: Create Your Own Number Activity: Design a Number

Counting & Place Value

Curriculum Alignment

Subject: Mathematics
Grade Level: Year 1 (First Grade)
Standard: Common Core State Standards (CCSS) for Mathematics

  • CCSS.MATH.CONTENT.1.NBT.A.1: Count to 120, starting at any number less than 120.
  • CCSS.MATH.CONTENT.1.NBT.B.2: Understand that the two digits of a two-digit number represent tens and ones.

Lesson Duration

Time: 60 minutes
Class Size: 30 students


Lesson Objectives

By the end of the lesson, students will be able to:
🔹 Count forward and backward within 100.
🔹 Skip count by 10s forward and backward.
🔹 Identify tens and ones in numbers up to 99.
🔹 Write numbers in standard and expanded form.
🔹 Compare numbers based on place value.
🔹 Solve place value word problems through hands-on activities.


Materials Needed

✅ Whiteboard and markers
✅ Number charts (1–100)
✅ Number blocks for place value
✅ Plastic coins (pennies, dimes, quarters)
✅ Colored pencils/crayons
✅ Place value charts
✅ Printed activity sheets (for each student)


Lesson Breakdown

1️⃣ Warm-Up Activity (10 minutes) – Counting Relay

👟 Interactive Counting Race

  • Split students into two teams.
  • One team counts forward from 1 to 50.
  • The other team counts backward from 50 to 1.
  • Have students pass a small ball to the next player as they count in sequence.
  • Introduce a quick challenge: Missing number fill-in on the board.

2️⃣ Whole-Class Instruction (15 minutes) – Place Value Introduction

📖 Explaining Tens and Ones

  • Display numbers from 10 to 99 and emphasize the tens and ones place.
  • Use colored number blocks to visually separate tens and ones.
  • Example: Show 56 as 5 tens (50) + 6 ones (6).
  • Ask students, “What would happen if I add one more to 56?”

3️⃣ Group Work (15 minutes) – Hands-On Learning Stations

🔄 Students rotate through three stations (5 minutes per station).

🧩 Station 1: Skip Counting by 10s

  • Students complete number sequences by writing missing multiples of 10 (10, 20, __, 40).
  • Use a jumping game: Students physically hop forward in 10s.

💰 Station 2: Place Value Fun with Coins

  • Students use pennies, dimes, and quarters to build numbers.
  • Example: Show 63 using dimes for tens and pennies for ones.
  • Write numbers in expanded form (e.g., 63 = 60 + 3).

🎨 Station 3: Tens & Ones Coloring Activity

  • Students color groups of tens and ones to match given numbers.

4️⃣ Independent Practice (10 minutes) – Mini Challenges

✏️ Students complete the following activities in their workbooks:

  1. Counting Forward from Any Number: Start counting forward from any given number between 30 and 90.
  2. Counting Backward from Any Number: Write the next five numbers backward from any number between 50 and 100.
  3. Expanded Form Matching: Match numbers to their correct expanded form (e.g., 72 → 70 + 2).

5️⃣ Wrap-Up (10 minutes) – Place Value Riddles & Discussion

Solve Fun Riddles

  • Example: “I am a number with 4 tens and 3 ones. What am I?”
  • Students discuss answers with partners.

🌟 Exit Ticket Challenge:

  • Provide students with two numbers (e.g., 45 and 54).
  • They compare which number is greater based on tens and ones.

Assessment & Differentiation

🔍 Formative Assessment

✔️ Observation during group activities.
✔️ Student responses during the Exit Challenge.
✔️ Workbook completion and accuracy in counting and place value tasks.

📌 Differentiation Strategies

For Struggling Learners:
🔹 Use visual aids (number blocks, charts) to reinforce place value understanding.
🔹 Provide additional guided practice with a teacher assistant.

For Advanced Learners:
⭐ Introduce three-digit numbers and challenge students to identify hundreds, tens, and ones.
⭐ Ask students to create their own place value riddles for their classmates.


Teacher Reflection

After the lesson, consider:

  • Did students grasp the concept of counting forward and backward?
  • Were students able to recognize tens and ones confidently?
  • Which activities engaged students the most?

🔄 Adjust the next lesson based on student understanding and engagement.

📢 Extension Idea: Set up a "Place Value Store" where students “buy” objects using different values of coins and explain their amounts using place value!

🎉 Congratulations! You've just led an engaging, hands-on, and interactive maths lesson!
