Your next great Lessn starts here.

Learning ‘One Less’ with Pictures – What does ‘One Less’ mean? – ‘One Less’ is the number before another number. – Counting down from 10 – Let’s count: 10, 9, 8… down to 1. – Using pictures to subtract 1 – Look at a group of items, then imagine 1 disappears. – Practice with fun examples | This slide introduces the concept of ‘One Less’ to Kindergarten students, which is a foundational skill in understanding subtraction and number order. Start by explaining that ‘One Less’ means finding the number that comes just before another number when we count backwards. Use visual aids like pictures or objects to help students visualize the concept. For example, show 10 apples, then remove one and count the remaining. Engage the class by asking them to count down from 10 to 1 together. Incorporate interactive activities where students can practice this concept with various sets of items or pictures, ensuring they grasp the idea of subtracting one to find ‘One Less’.

Understanding ‘One Less’ – ‘One Less’ means the number before – Example: 5 apples, take 1 away – If you start with 5 and take away 1, you now have 4 apples – Counting down to show ‘One Less’ – We’ll count backwards from 10 to 1 together – Practice with different numbers – Try with numbers up to 10 using toys or fingers | This slide introduces the concept of ‘One Less’ to Kindergarten students. Begin by explaining that ‘One Less’ is simply the number that comes just before another number. Use tangible examples like apples to illustrate this point. Demonstrate by physically removing an item, or showing a picture of the item being removed, to help them visualize the concept. Engage the class by counting backwards together from 10 to 1, reinforcing the idea of ‘One Less’ with each step. Encourage the students to practice with different numbers up to 10, using classroom objects or their fingers to make the activity interactive and fun. The goal is for students to understand and recognize the pattern of counting down to find ‘One Less’.

Counting Down: One Less Than – Start at 10 and count back – Each number is ‘one less’ – ‘One less’ means subtracting 1 – Say it with me: 10 to 1 – Practice together: 10, 9, 8… – Understand ‘one less’ concept – Grasp the idea of decreasing numbers | This slide is aimed at helping Kindergarten students understand the concept of ‘one less’ through counting backwards from 10. It’s a fundamental skill in early math that sets the foundation for subtraction. Start by counting down from 10 to 1 with the class, emphasizing the ‘one less’ concept with each step. Use visual aids like fingers or objects to represent each number, removing one each time to visually demonstrate ‘one less’. Encourage students to join in and count aloud together. This interactive approach helps solidify their understanding of sequential order and the idea of decrementing numbers. After the activity, discuss with the class how each number is one less than the previous number, reinforcing the concept.

Counting One Less with Apples – Observe pictures of apples – Take one apple away – If we start with 5 apples and remove 1, how many are left? – Count the remaining apples – Use your fingers to help count the apples left – Understand ‘one less’ – ‘One less’ means we have one fewer than we started with | This slide is designed to teach Kindergarten students the concept of ‘one less’ using visual aids like pictures of apples. Start by showing a picture with a certain number of apples, up to 10. Ask the students to count the apples first. Then, visually remove one apple from the picture and ask the students to count how many apples are left. Encourage them to use their fingers to count and to understand that when we say ‘one less’, we are counting back by one. Reinforce the concept by repeating with different numbers of apples, and always verify the understanding by asking the students to explain the concept back to you in their own words.

Practice Time: One Less – Observe pictures with objects – Count the objects you see – If you see 5 apples, how many are there? – Determine ‘one less’ than the count – If there are 5 apples, one less would be 4 apples – Share your answer with the class | This slide is an interactive activity for students to practice the concept of ‘one less.’ Display pictures with different numbers of objects, up to 10. Ask the students to count the objects and then think about what ‘one less’ would be. For example, if there are 5 apples in the picture, ask the students what ‘one less’ would be, guiding them to the answer of 4 apples. Encourage the students to participate and share their answers with the class. This activity helps to reinforce their counting skills and understanding of the concept of ‘one less.’ Prepare several examples with different numbers of objects and ensure that every student has a chance to respond.

Let’s Play a Game: One Less! – Roll the dice and move forward – What’s ‘one less’ than your roll? – If you roll a 4, ‘one less’ is 3 – Say it out loud – Practice ‘one less’ with friends – Take turns and help each other | This interactive game is designed to help Kindergarten students understand the concept of ‘one less’ in a fun and engaging way. By using dice, students will be able to visualize the numbers and physically move spaces, which reinforces kinesthetic learning. After rolling the dice, prompt the student to think about what number is ‘one less’ than the number they rolled and encourage them to articulate it. This activity not only teaches subtraction in a simple form but also encourages social interaction and cooperative learning as they play with peers. The teacher should monitor the game, provide guidance, and celebrate correct answers to build confidence. Possible variations of the activity could include using different objects to count, such as blocks or counters, to further reinforce the concept.

Class Activity: One Less Hunt – Let’s explore the classroom together – Find objects with numbers up to 10 – Look for items like blocks or books with numbered pages – Say the number that is ‘one less’ – If you see the number 5, ‘one less’ is 4 – Have fun learning numbers! | This interactive activity is designed to help Kindergarten students understand the concept of ‘one less’ in a fun and engaging way. Set up the classroom with various objects or pictures that have numbers up to 10 clearly labeled on them. Encourage the children to search for these items and, once found, to identify the number that is one less than the displayed number. For example, if a student finds a picture with the number 7, they should say ‘six’. This activity not only reinforces number recognition and counting skills but also introduces basic subtraction in a practical context. Possible variations of the activity could include pairing students up, using a timer for a ‘speed hunt’, or having students draw their findings.

Fantastic Work on ‘One Less’! – Celebrating ‘One Less’ mastery – ‘One less’ means the previous number – If we have 5 apples and take 1 away, we have 4 apples. – Applause for today’s effort – Keep practicing at home! – Try using toys or snacks to practice. | This slide is meant to wrap up the lesson on ‘One Less’ by celebrating the children’s understanding and effort. Reinforce the concept that ‘one less’ refers to the number that comes before another number in a sequence. For example, before 6, we have 5. Praise their hard work and encourage them to continue practicing the concept at home with their toys or during snack time, making it a part of their daily routine. This will help solidify their understanding and make learning fun.
