Your next great Lessn starts here.

Math Adventures: One More & One Less – Today’s focus: Numbers up to 10 – Learn ‘One More’ concept – If we have 4 apples, one more would be 5 apples. – Explore ‘One Less’ idea – If we have 6 candies, one less would be 5 candies. – Engaging number activities | Welcome to our Math Adventures class, little explorers! Today, we’re embarking on a numerical journey to understand the concepts of ‘One More’ and ‘One Less.’ These are fundamental ideas that will help students grasp basic arithmetic and number relationships. Through interactive activities, we will practice adding one to a number to see how it changes and taking one away to see how it decreases. The activities will involve physical objects like blocks or counters to visually and tangibly demonstrate these concepts, making it easier for our kindergarten students to comprehend and enjoy the learning process.

Understanding ‘One More’ – ‘One more’ means adding 1 – Counting and adding one – Let’s count: 1, 2, 3, each time we say a number, we add one more! – Example: 2 becomes 3 – If we have 2 apples and get 1 more, now we have 3 apples! – Example: 4 becomes 5 – Starting with 4 fingers, add 1 more finger, and we have 5 fingers! | This slide introduces the concept of ‘one more’ to Kindergarten students. Begin by explaining that ‘one more’ is simply the idea of adding 1 to any number. Use visual aids like fingers or objects to help students visualize the concept. Engage the class in a counting activity where they add one more each time they say a number. Provide clear examples, such as 2 becoming 3 and 4 becoming 5, to solidify their understanding. Encourage students to think of their own examples and share them with the class. The goal is to make them comfortable with the idea of incrementing numbers by one.

Let’s Practice ‘One More’ – Understanding ‘one more’ – Example with 3 apples – If you start with 3 apples and get another, you’ll have 4 apples! – Finding ‘one more’ than 5 – What number comes after 5? That’s ‘one more’! – Finger activity for ‘one more’ – Show ‘one more’ than a number using your fingers. | This slide is designed to help Kindergarten students grasp the concept of ‘one more.’ Start by explaining that ‘one more’ means adding one to the current amount. Use the example of 3 apples, and if we add one more, we have 4 apples. Then, ask the students to think about what comes after 5 to practice finding ‘one more.’ For the activity, have the students use their fingers to show ‘one more’ than a given number. This could be done by holding up a certain number of fingers and then adding one more. It’s a tactile and visual way to reinforce the concept. Make sure to walk around the classroom to assist and praise the students as they engage in the activity.

Understanding ‘One Less’ – ‘One less’ means taking away 1 – Count backwards to find ‘one less’ – If we have 8 and step back one, we get 7 – Example: 6 becomes 5 – Starting from 6, if we take 1 away, we have 5 – Example: 8 becomes 7 – Starting from 8, if we take 1 away, we have 7 | This slide introduces the concept of ‘one less’ to Kindergarten students. Begin by explaining that ‘one less’ is like taking one toy away from a group of toys. Use physical objects or fingers to demonstrate counting backwards, which helps them visualize the concept. The examples provided should be clear and tangible, such as subtracting one block from a stack. Encourage students to practice with different numbers up to 10, using toys, blocks, or drawings to reinforce the concept. The goal is for students to understand subtraction as a form of taking away and to become comfortable with the idea of ‘one less’ in a fun and interactive way.

Let’s Practice ‘One Less’ – Understanding ‘one less’ – Example with 4 cookies – If you start with 4 cookies and eat 1, you have 3 left. – Find ‘one less’ than 7 – Think about what number comes before 7. – Finger activity for ‘one less’ – Show with fingers: if you hold up 7 fingers, then put one down. | This slide is designed to help Kindergarten students understand the concept of ‘one less’ in a fun and interactive way. Start by explaining that ‘one less’ means taking away one from a group. Use the cookie example to visually demonstrate this concept. Ask the students to visualize having four cookies and eating one, then count how many are left. For the second point, encourage the students to think about the number that comes just before 7. The activity with fingers is a hands-on approach to reinforce the concept; have the students hold up a certain number of fingers and then put one down to show ‘one less’. This tactile method helps solidify their understanding. During the next class, review the concept and ask students to demonstrate ‘one less’ with different numbers up to 10.

Fun with Numbers: One More & One Less – Play games to learn ‘one more’ and ‘one less’ – Use blocks to add or take away one – If you have 4 blocks, add 1 more. How many now? – Sing number songs together – ‘Five Little Ducks’ can show subtracting one – Understand ‘one more’ and ‘one less’ – Practice with different numbers up to 10 | This slide is designed to introduce Kindergarten students to the concepts of ‘one more’ and ‘one less’ through interactive play. Encourage the use of tangible objects like blocks or toys to visually demonstrate adding or taking away one item. Incorporate music and movement with songs that involve counting up or down to reinforce the concepts. During the class, have a variety of games and activities ready, such as a ‘one more’ hopscotch or a ‘one less’ treasure hunt, to cater to different learning styles. The goal is to make the learning process enjoyable and memorable, helping students to grasp the basic principles of addition and subtraction within the number range up to 10.

Number Line Hopscotch – Play hopscotch with numbers 1-10 – Land on a number, say ‘one more’ – If you land on 5, say ‘one more is 6’ – Also say ‘one less’ for each number – If you land on 5, say ‘one less is 4’ – Help friends and enjoy jumping! | This interactive class activity is designed to help Kindergarten students understand the concepts of ‘one more’ and ‘one less’ in a fun and physical way. Set up a hopscotch grid with numbers 1 through 10. As students hop on a number, they will practice identifying the number that is one more and the number that is one less than the one they landed on. This reinforces their counting skills and understanding of number order. Encourage students to assist each other and ensure everyone gets a turn. Possible variations of the activity could include using a dice to determine how many spaces to hop, calling out numbers for students to jump to, or having students clap the number of times for ‘one more’ and ‘one less’. The goal is to create a supportive and enjoyable learning environment.

Review and Goodbye: Counting Adventures – Recap: ‘one more’ and ‘one less’ – We learned to add and subtract one from numbers up to 10. – Home activity with toys – Use toys to practice ‘one more’ and ‘one less’. – Praise for today’s effort – Anticipation for next lesson | As we conclude today’s lesson, it’s important to review the concepts of ‘one more’ and ‘one less’ to reinforce the children’s understanding. Encourage them to demonstrate their learning at home using their toys, which will help solidify the concept in a fun and familiar context. Offer praise to acknowledge their hard work and progress in today’s class, and build excitement for the next lesson to keep them engaged and looking forward to learning more about Math. Remember to provide a supportive and positive environment for the children to express what they’ve learned.
