Your next great Lessn starts here.

Welcome to Subtraction! – Greetings little mathematicians! – Today’s lesson: taking away with subtraction – Subtraction means taking some away from a group – Subtraction shows us what’s left – If you have 5 apples and eat 2, subtraction tells you 3 are left – Let’s practice with numbers up to 10 – We’ll use fun examples to learn subtraction | This slide introduces Pre-K students to the concept of subtraction in an engaging and understandable way. Start by greeting the students warmly to create a welcoming learning environment. Explain that subtraction is like taking away items from a group and finding out how many items remain. Use tangible examples like toys or snacks to illustrate the concept, as this will help them grasp the idea of ‘taking away’. Encourage the children to use their fingers to subtract numbers up to 10, making the lesson interactive. Prepare to demonstrate with real objects or pictures to show subtraction in action. The goal is to make the students comfortable with the idea of subtraction as a fun activity.

Understanding Subtraction: Taking Away – Subtraction means taking away – If you have 5 apples and eat 2, you take away 2 from 5. – The subtraction sign: – – It’s like a little dash that tells us to take away. – Taking away with numbers – For example, 10 – 2 is taking 2 away from 10, which leaves us 8. – Subtraction in everyday life – Like when you have 10 candies and give 3 to a friend, you subtract 3 from 10. | This slide introduces the concept of subtraction to Pre-K students by explaining it as ‘taking away’. Use real-life examples like apples and candies to illustrate the concept. Show the subtraction sign and demonstrate how it is used between numbers to indicate that one number is taken away from another. Engage the students with simple subtraction problems using numbers up to 10, and encourage them to use their fingers or objects to physically take away and count what’s left. This tactile approach helps them grasp the concept of subtraction more concretely.

Subtraction Sentences Up to 10 – What is a subtraction sentence? – It’s like a math story with numbers and a minus sign. – Example: 5 – 2 = 3 – Taking away 2 apples from 5 apples leaves us 3 apples. – Create your own subtraction sentences – Match models to sentences – Use toys or drawings to show subtraction. | This slide introduces the concept of subtraction sentences to Pre-K students. Begin by explaining that a subtraction sentence is a simple way to show taking away one number from another. Use tangible examples like apples or toys to illustrate subtraction. Encourage the children to use objects they can touch and count to create their own subtraction sentences. This hands-on approach helps them visualize the concept. Finally, have them match physical models or pictures to written subtraction sentences to reinforce the connection between the abstract and the concrete. This activity will prepare them for understanding subtraction as they progress in math.

Matching Models to Subtraction Sentences – Use objects to show subtraction – Example: 5 apples, eat 2, how many left? – Starting with 5 apples, if we eat 2, we’re left with 3 apples – Match apples left to subtraction sentence – Which sentence shows 5 minus 2 equals 3? – Subtraction is taking away – Understand subtraction as ‘taking away’ from a total | This slide is aimed at helping Pre-K students understand the concept of subtraction by using tangible objects like apples. Start by explaining subtraction as ‘taking away’ from a group. Use the example of having 5 apples and eating 2 to illustrate this point. Show the students how to count the remaining apples to find the answer. Then, guide them to match the number of apples left (3) with the correct subtraction sentence (5 – 2 = 3). Encourage the students to use their fingers or other classroom objects to practice this concept. The goal is for students to visualize the subtraction process and connect it with the written numerical expression.

Let’s Practice Subtraction Together! – I’ll show a subtraction model – You find the matching sentence – Count carefully on your own – We can count together if you’re unsure – Example: If there are 5 apples and we eat 2, how many are left? | This slide is designed to engage Pre-K students in a hands-on activity to practice subtraction up to 10. Display different models, such as pictures or physical objects, and ask the students to identify the correct subtraction sentence that matches the model. Encourage them to count carefully and independently, but be ready to assist and count together if needed. Use clear and simple examples to demonstrate the concept. Possible activities include using toys, fingers, or drawings to represent subtraction problems. For instance, show 5 toy cars and ‘take away’ 2, then ask the students to tell you the subtraction sentence (5 – 2 = 3). This interactive approach helps solidify their understanding of subtraction as ‘taking away’ and the concept of ‘how many are left’.

Your Turn to Try: Match the Model! – Observe the objects carefully – Count how many are left after subtraction – If there were 5 apples and we ate 2, how many do we have now? – Select the correct subtraction sentence – Does ‘5 – 2 = 3’ show our apple count correctly? – Confirm if the sentence matches the model | This slide is an interactive activity for students to apply their understanding of subtraction by matching models to subtraction sentences. Encourage the children to look at the objects presented and use their counting skills to determine the remaining quantity after some are taken away. Then, they should choose the subtraction sentence that correctly represents the action performed. For example, if there are 5 apples and 2 are taken away, the correct sentence is ‘5 – 2 = 3’. This exercise will help reinforce their comprehension of subtraction as taking away and the concept of finding ‘how many are left’. Provide guidance and be ready to assist if they struggle with counting or selecting the right sentence. Prepare to offer praise and positive reinforcement as they successfully complete the task.

Class Activity: Subtraction with Toys – Create subtraction stories with toys – Count your toys before subtraction – How many toys do you start with? – Take some toys away and count again – How many are left after you take some away? – Share your story with the class | This interactive class activity is designed to help Pre-K students understand the concept of subtraction in a fun and tangible way. By using toys, students can visually see the subtraction process. Start by having each student pick a set number of toys and count them aloud. Then, instruct them to remove a few toys and count the remaining ones. Encourage them to articulate their subtraction story, for example, ‘I had 5 blocks, I took away 2, now I have 3.’ This activity not only teaches subtraction but also reinforces counting skills. Possible variations of the activity could include using different types of toys, subtracting in pairs, or even introducing the concept of ‘zero’ by taking all toys away. The goal is to make the learning process as engaging as possible while solidifying the foundational math concept of subtraction.

Review and Goodbye! – Recap on subtraction concepts – Subtraction means taking away from a total number. – Create your own subtraction sentence – Try making a sentence like ‘5 – 2 = 3’. – Celebrate today’s achievements – Anticipate more math adventures | This slide is aimed at wrapping up the session by revisiting the key concepts of subtraction that were taught today. Encourage the children to reflect on what they have learned by asking them to articulate the concept of subtraction in their own words. Prompt them to create their own subtraction sentences, reinforcing the idea that subtraction represents taking away from a group. Praise their efforts and progress throughout today’s lesson to boost their confidence. End the class on a high note, leaving the children excited for the next lesson. For the next class, prepare a set of new and engaging subtraction problems to continue building their skills.
