Your next great Lessn starts here.

Math Adventures: Learning ‘One Less’ – Greet our little mathematicians – Today’s lesson: ‘One Less’ with pictures – We’ll use images to subtract one and see what we get – ‘One Less’ helps with counting – Subtracting one helps us understand numbers better – Useful for games and everyday life – Knowing ‘One Less’ is fun for games like ‘Musical Chairs’ | Welcome the children warmly to the lesson to create an engaging learning environment. Introduce the concept of ‘One Less’ by using visual aids like pictures that show a group of objects and then one less of those objects. Explain how this concept is a basic form of subtraction that will aid in their counting skills. Provide examples from daily life or common games to make the concept relatable and easier to grasp. Encourage the children to participate by asking them to visualize ‘One Less’ in different scenarios. Prepare to demonstrate with real objects or images during the lesson to enhance understanding.

Understanding ‘One Less’ – ‘One Less’ means taking one away – Example with 5 apples – If you start with 5 apples and take away 1, you now have 4 apples. – Visualize ‘One Less’ with pictures – We’ll use images to show removing one item from a group. – Practice finding ‘One Less’ – We’ll do activities with different objects to learn this concept. | This slide introduces the concept of ‘One Less’ to Pre-K students using a relatable example of apples. Start by explaining that ‘One Less’ means we take away one from a group. Use a visual aid, like a picture of 5 apples, and then physically remove one to show there are 4 left. This visual representation helps young learners grasp the concept of subtraction in a concrete way. Follow up with interactive activities where students can practice finding ‘One Less’ with various objects or pictures, reinforcing the concept through repetition and engagement.

Counting Down: One Less Than Five – Start with 5 stars – If one star goes away – Now there are 4 stars – Count the stars left – Counting helps us see the answer is 4 – Understanding ‘One Less’ – ‘One Less’ means taking away 1 item | This slide is aimed at teaching Pre-K students the concept of ‘One Less’ using visual aids like stars. Start by showing them 5 stars and then visually remove one, asking the students to count the remaining stars. This interactive approach helps them understand subtraction in a simple and engaging way. Encourage the students to use their fingers to represent the stars as they count down from 5 to 4. This tactile method reinforces the learning process. Make sure to praise their effort as they grasp the concept of ‘One Less’.

One Less with Ducks – Start with 5 ducks – If one duck swims away – How many ducks are left? – We’ll have one less than 5, which is 4 – Let’s count together! – Counting down helps us learn ‘One Less’ | This slide is designed to teach Pre-K students the concept of ‘One Less’ in a fun and engaging way using ducks as an example. Start by showing a picture of 5 ducks to the class. Then, tell a story where one of the ducks swims away, prompting the question of how many ducks are left. Encourage the students to count the remaining ducks aloud together. This interactive approach helps them understand subtraction in a simple form. Reinforce the concept by repeating with different numbers of ducks up to 5, and always counting down to find ‘one less’. The goal is to make the learning process enjoyable and memorable by associating it with a visual and relatable scenario.

Learning ‘One Less’ with Our Fingers – Start with 5 fingers raised – Put one finger down – Now we have 4 fingers up! – Count the remaining fingers – We’re showing 4 fingers, that’s one less than 5 – Practice ‘One Less’ with fun – Use your hands to learn subtraction | This slide is an interactive activity designed for Pre-K students to understand the concept of ‘One Less’ using their fingers. Start by asking the students to hold up all five fingers, then instruct them to put one finger down. Have them count the remaining fingers to reinforce the concept that putting one finger down means one less. This hands-on activity not only makes learning subtraction tangible but also engages students in a fun and memorable way. Encourage them to repeat the activity with different numbers of fingers raised to practice ‘One Less’ up to five. The goal is to help them visualize subtraction and understand that ‘One Less’ means taking away one.

Class Activity: ‘One Less’ Game – Play the ‘One Less’ game – Take one block away – Remove a single block from the tower – Count the remaining blocks – How many blocks are left now? – Learn ‘One Less’ as a class | This interactive game is designed to help Pre-K students understand the concept of ‘One Less’ in a fun and engaging way. Set up a small tower of blocks (up to 5) for each child. As each student takes a turn, they will remove one block and then count the remaining blocks aloud. This activity reinforces the concept of subtraction by one and helps with number recognition and counting skills. For variation, you can use different colored blocks, have students draw pictures with one less object, or use stickers. Encourage students to articulate the change in quantity after removing a block to enhance their understanding.

Celebrating ‘One Less’ Mastery – ‘One Less’ means taking one away – Count what remains after removing one – If you had 5 apples and ate one, how many are left? – Practice makes perfect counters – You’re doing great with counting! – Keep practicing at home with toys or snacks! | This slide is a conclusion to reinforce the concept of ‘One Less’. It’s a celebration of the students’ understanding and progress. Remind them that ‘One Less’ is simply the act of taking one item away from a group and then counting the remaining items. Use everyday examples like eating an apple from a group of five to illustrate the concept. Encourage the children to continue practicing with items at home, such as toys or snacks, to become more confident in their counting skills. Praise their efforts and progress to boost their confidence and interest in learning more about numbers.
