Your next great Lessn starts here.

Math Adventures: One Less with Pictures! – Greet our young mathematicians – Today’s journey: ‘One Less with Pictures’ – Understand ‘One Less’ through fun – ‘One less’ means taking one away – Practice with pictures up to 10 – Use images to show subtraction of one item | Welcome students to the class with enthusiasm to set a positive tone for learning. Introduce the concept of ‘One Less’ as a basic subtraction principle where one item is taken away from a group. Use visual aids like pictures or objects to demonstrate this concept, ensuring that the examples do not exceed 10 items to keep it simple for Pre-K level understanding. Encourage participation by asking students to identify ‘one less’ in different scenarios. Prepare interactive activities where students can physically remove an item from a group to find ‘one less’, fostering hands-on learning.

Understanding ‘One Less’ – Counting together from 1 to 10 – ‘One less’ is like magic disappearing – Imagine one thing vanishing into thin air! – Example with 5 apples – If we start with 5 and take 1 away, we’re left with 4 – How many apples left? | This slide introduces the concept of ‘one less’ to Pre-K students using a relatable and visual example of apples. Start by engaging the students in a counting activity from 1 to 10 to ensure they are familiar with the numbers. Explain ‘one less’ as a fun magic trick where one item disappears. Use props like toy apples to visually demonstrate the concept. For instance, show 5 apples, then remove one and ask the students to count how many are left. This interactive approach helps them grasp the idea of subtraction in a simple and enjoyable way. Encourage the children to think of other examples where they might have ‘one less’ of something, like cookies or blocks, to reinforce the concept.

Let’s Play with Pictures: Counting Apples – Observe 10 apples on screen – Imagine 1 apple falls down – How many apples are left? – If we take 1 away from 10, what number do we get? – Let’s count the remaining apples! – Counting down from 10 to 1 helps us learn ‘one less’ | This slide is designed to teach Pre-K students the concept of ‘one less’ in a fun and interactive way using visual aids. Display an image of 10 apples and then visually remove one, asking the students to count the remaining apples. This activity helps them understand subtraction in a concrete manner. Encourage the children to count aloud together and use their fingers if necessary. The goal is to make them comfortable with the idea that taking one away from a group reduces the total count by one. You can repeat the activity with different numbers up to 10 to reinforce the concept.

Finding ‘One Less’ with Toys – Start with 6 toys in the box – Give 1 toy to a friend – Now there’s one less toy to play with – How many toys are left? – Use your fingers to count 5 toys – Let’s count the toys together – Counting helps us see the answer is 5 | This slide is designed to teach Pre-K students the concept of ‘one less’ in a fun and interactive way using toys. Start by showing a picture of a toy box with 6 toys. Explain that if we give one toy away, we have one less toy. Ask the students to visualize giving a toy to a friend and then count the remaining toys in the box. Encourage them to use their fingers or physical objects to count down from 6 to 5. This hands-on activity helps them understand subtraction in a simple and relatable context. Make sure to praise their counting and reinforce the concept that ‘one less’ means we take away one item and count what’s left.

One Less with Balloons – Start with 8 balloons – Imagine 1 balloon flies away – A balloon drifts up to the sky – How many balloons left? – Use your fingers to subtract one – Let’s count remaining balloons – Count the balloons one by one | This slide is designed to teach Pre-K students the concept of ‘one less’ in a fun and interactive way using the example of balloons. Start by showing a picture of 8 balloons, then tell a story of one balloon flying away to capture their imagination. Ask the students how many balloons are left to encourage them to think. Then, guide them to count the remaining balloons aloud together. This activity helps develop their counting skills and understanding of subtraction in a simple, visual manner. Make sure to use clear and colorful images of balloons and engage with the children by asking them to use their fingers to count down from 8 to 7.

Practice Time: Finding ‘One Less’ – Let’s practice ‘one less’ – Look at the pictures carefully – Observe the number of objects in each picture – Tell me what is ‘one less’ – If there are 5 apples and we take 1 away, how many are left? – Ready? Let’s count together! | This slide is an interactive activity designed to help Pre-K students understand the concept of ‘one less’. Display pictures with a certain number of objects, up to 10, and ask the students to identify what one less of that number would be. For example, show a picture with 6 balloons and ask the students to show or say what one less would be. Encourage them to use their fingers to count if needed. This activity helps to reinforce counting skills and the concept of subtraction in a visual and engaging way. Be prepared with a variety of images and ensure that each student has a chance to participate. Praise their efforts to build confidence.

Class Activity: ‘One Less’ Hunt – Explore the classroom on a ‘One Less’ hunt – Find grouped items and remove one – Count how many items remain – Share your findings with the class | This interactive activity is designed to help Pre-K students understand the concept of ‘one less’ in a fun and engaging way. Set up the classroom with various items grouped together, ensuring they are in quantities up to 10. Encourage the children to walk around the room and choose a group of items. Instruct them to take one item away from the group and then count the remaining items. Afterward, have each student share their experience with the class, discussing what they started with, what they took away, and how many were left. This will reinforce the concept of subtraction by one in a tangible manner. Possible variations of the activity could include using different types of items, pairing students to work together, or even incorporating a storytelling element where each group of items is part of a story.

Congratulations, ‘One Less’ Wizards! – Celebrate finding ‘one less’ – ‘One less’ means taking one away – Like having 10 candies and eating 1, now you have 9. – You’re now ‘One Less’ wizards! – Keep practicing at home! – Try with toys or snacks to learn more. | This slide is meant to wrap up the lesson on finding ‘one less’ with a positive reinforcement of the students’ achievements. It’s important to reiterate the concept of ‘one less’ as simply removing one item from a group, which helps solidify their understanding. Encourage the children to continue practicing this concept outside of the classroom with everyday items, which will help them grasp the practical application of subtraction in a fun and engaging way. Praise their efforts in becoming ‘One Less’ wizards and suggest that they can demonstrate their new skills to their family and friends.
