Welcome to Counting! – Greetings First Graders! – Today’s goal: Count to 120 – We’ll learn to count from 1 all the way to 120 – Why counting matters – Counting is the foundation of math skills – Counting on a number line – Using a number line helps us see the order of numbers | This slide is an introduction to the concept of counting for first graders, aiming to create excitement about learning to count up to 120. Emphasize the importance of counting as a basic math skill that is used in many aspects of everyday life. Explain that counting is not just about reciting numbers but understanding their sequence and value. Introduce the number line as a visual tool that will help them see the progression of numbers from 1 to 120. Encourage the students to think about where they see numbers in their daily lives and how counting is involved. Prepare to engage the students with interactive counting activities using the number line.

Exploring Number Lines – What is a number line? – A straight line with numbers at equal spaces – Number line helps order numbers – It shows how numbers come after or before each other – Counting using a number line – We can count up or down by moving along the line – Practice with a number line | Introduce the concept of a number line to the students by explaining it as a straight path that has numbers at equal intervals, much like the marks on a ruler. Emphasize that a number line can be used to visually understand the sequence of numbers and can help in counting forwards or backwards. Demonstrate this by counting from 1 to 120 on the number line and then back. Encourage students to practice by pointing to numbers as you call them out or by asking them to show what number comes before or after a given number. This will help solidify their understanding of number order and the concept of a number line.

Counting on a Number Line – Number lines help us count – Start at 0, count to 30 – Begin at the start and count up – Each number is one step – Imagine hopping from one number to the next – Practice moving on the line – Use your finger to trace from 0 to 30 | This slide introduces students to the concept of using a number line as a visual aid for counting. It’s important to demonstrate how each number on the line represents a single count or step. Start with the number 0, and show how to move sequentially to the number 30, emphasizing the one-to-one correspondence between the numbers and steps taken. Encourage students to use their fingers to trace along the number line as they count, reinforcing the concept of number sequence and the physical movement associated with each count. This tactile approach helps solidify the counting process in a child’s mind.

Big Numbers on the Number Line – Numbers can be small or big – Big numbers have patterns too – Just like 1, 2, 3, numbers like 118, 119, 120 are in order – Number lines help us see the pattern – A number line shows us how numbers are lined up – Counting in tens on the number line – Skip count by 10 to move faster on the number line | This slide introduces students to the concept of large numbers within the context of a number line, emphasizing that the pattern they’ve learned with smaller numbers applies to larger ones as well. It’s important to show them that a number line is a visual tool that helps us understand the sequence of numbers. To simplify the concept of counting to 120, teach them to count by tens, which is a more manageable strategy for first graders. During the lesson, use a physical number line in the classroom to demonstrate counting in tens, and encourage students to participate by pointing to the numbers as they count together. This interactive approach will help solidify their understanding of number sequences and the use of number lines.

Practice Time: Counting on Number Lines – Let’s count on our number lines – Point to number 50 together – 50 is halfway to 100 on the line – Now find and point to number 75 – 75 is three quarters to 100 – Practice counting up and down – Try jumping forwards or backwards by 10s | This slide is an interactive activity for students to practice using number lines. Start by guiding the whole class to count together, ensuring they understand how to use the number line. Then, ask them to point to specific numbers like 50 and 75. This will help them get familiar with the concept of intervals and the position of numbers relative to each other. Encourage the students to count out loud and use their fingers to trace the numbers on their number lines. For advanced practice, have them jump in intervals of 10s to quickly move up or down the number line. This activity reinforces their understanding of number sequences and the spatial representation of numbers.

Counting Past 100 on the Number Line – Counting past 100 is easy – Just add one step at a time – Imagine hopping forward one number each time – Let’s count: 100 to 120 – We’ll do it as a class, starting at 100 and ending at 120 – Practice makes perfect – The more we practice, the better we’ll get! | This slide is designed to help first graders understand that counting past 100 follows the same simple pattern as counting smaller numbers. Start by reinforcing the concept that each step on the number line represents adding one more. Then, lead the class in counting together from 100 to 120, ensuring that they understand the sequence continues beyond 100. Encourage participation and make it fun, perhaps by clapping or stepping as each number is counted. Emphasize the importance of practice in becoming comfortable with higher numbers. As an activity, you could have students draw their own number lines and mark the numbers as they count, or use physical steps in the classroom to represent the number line.

Class Activity: Create Your Number Line! – Let’s make our number line – Gather paper, markers, stickers – We’ll use these to create our lines – Mark numbers up to 120 – Place a sticker for every number – Practice counting with fun! – Count out loud as you place stickers | This activity is designed to help first graders understand and practice counting to 120 in a hands-on way. Provide each student with a long strip of paper and a set of markers and stickers. Guide them to mark the numbers from 1 to 120 on the paper, placing a sticker at each number. Encourage them to say the numbers out loud as they work, reinforcing their counting skills. This will also help them visualize the sequence of numbers and understand the concept of a number line. For differentiation, some students can work in pairs, while others might challenge themselves to mark certain multiples. Ensure that every student is engaged and assist where necessary.

Counting Success! – Excellent counting work today! – Number lines are counting helpers – A line with numbers in order helps us count from 1 to 120 – Practice makes perfect – The more you count, the better you’ll get – You’re on your way to be a counting star! | This slide is meant to congratulate the students on their hard work during the lesson and to reinforce the importance of the number line as a tool for counting. It’s crucial to encourage them to keep practicing, as this will help solidify their understanding of numbers and their sequence. Remind them that with practice, they can become very skilled at counting, just like a star shines brightly in the sky. Offer words of encouragement and let them know that they are making great progress in their mathematical journey.
