Welcome to Subtraction! – Greet our little mathematicians – Today’s lesson: Take away up to 10 – We’ll use numbers 1 through 10 to subtract – Subtraction makes numbers smaller – Imagine having 10 blocks, then taking some away – It’s like a magic number trick! – Watch how the total changes when we subtract | This slide is designed to introduce Pre-K students to the concept of subtraction in an engaging and age-appropriate way. Start with a warm greeting to make the children feel comfortable and excited about the lesson. Explain that subtraction is a process where we take away numbers from a larger number, and it’s like a magic trick because the numbers get smaller. Use tangible examples like blocks or toys to demonstrate subtraction visually, which helps young learners grasp the concept better. Encourage the children to participate by asking them what happens when we take away some of their toys or blocks. The goal is to create a fun and interactive environment where students can begin to understand and enjoy the basics of subtraction.

Understanding Subtraction: Taking Away Cubes – Subtraction means taking away – Start with a bigger number – If we have 10 apples and give away 2, we subtract 2 from 10. – Take some away and see what’s left – After giving away, count the remaining to find the answer. – Like sharing blocks with a friend – Imagine having 10 blocks, you give 3 to a friend, how many do you have now? | This slide introduces the concept of subtraction to Pre-K students using a relatable example of sharing blocks. Subtraction is explained as the process of taking away from a total amount. Teachers should use physical objects like blocks or toys to demonstrate subtraction, allowing students to engage in hands-on activities. For instance, start with 10 blocks, ask a student to give away a certain number, and then count the remaining blocks together. This visual and interactive approach helps young learners grasp the concept of ‘taking away’ and ‘seeing what is left’. Encourage students to think of other examples where they might give something away and have less than they started with, reinforcing the idea of subtraction in everyday life.

Learning the Subtraction Symbol – Subtraction symbol is a dash: – – It means ‘take away’ – Practice saying ‘minus’ – When we see -, we say ‘minus’ – Let’s try subtracting together! – Example: 5 – 2 is ‘5 minus 2’ | This slide introduces the subtraction symbol to Pre-K students. It’s important to emphasize the visual aspect of the symbol and associate it with the concept of ‘taking away’. Use simple language and repetition to help them remember. Encourage the students to say ‘minus’ every time they see the symbol. You can use physical objects like cubes or counters to demonstrate subtraction in a tangible way. For instance, start with 5 cubes and take 2 away to show 5 – 2. This hands-on activity will help them understand the concept of subtraction more effectively.

Let’s Try Together: Subtracting Cubes – Start with 10 cubes – Take away 2 cubes – How many cubes are left? – Count remaining cubes together – Understand 10 – 2 equals… – 10 minus 2 equals 8 | This slide is an interactive activity designed to introduce Pre-K students to the concept of subtraction. Start by showing the students 10 physical cubes. Ask a volunteer to remove 2 cubes and then engage the entire class in counting the remaining cubes. This visual and hands-on approach helps solidify the concept of ‘taking away’ in subtraction. Reinforce the equation ’10 – 2 equals 8′ by writing it on the board and reading it out loud. Encourage the students to repeat the equation to enhance memorization. Prepare to offer additional support to students who may struggle with the concept and have alternative examples ready if needed.

Using Our Fingers to Subtract – Use fingers for subtraction – Start with 10 fingers up – All fingers up means 10 – Take away 3 fingers – Fold down 3 fingers to subtract – Count the remaining fingers – How many fingers are still up? | This slide introduces the concept of subtraction to Pre-K students using a tactile and visual method using their fingers. Start by explaining that subtraction means taking away. Have the children hold up all 10 fingers to represent the number 10. Then, instruct them to fold down a specific number of fingers when you say ‘take away’ followed by a number. This will help them visually and physically see the subtraction process. After they put down the specified number of fingers, ask them to count the number of fingers still up to find the answer. This activity can be repeated with different numbers to strengthen their understanding of subtraction up to 10.

Subtraction Stories with Toy Cars – Start with 5 toy cars – Give 2 cars to a friend – How many cars are left? – Learn subtraction: 5 – 2 equals… – Subtraction means taking away, so 5 cars take away 2 leaves us with 3 cars. | This slide introduces the concept of subtraction through a relatable story involving toy cars. It’s designed to help Pre-K students understand subtraction as ‘taking away.’ Start by showing 5 toy cars and then visually demonstrate giving 2 cars away to a friend. Ask the students to count how many cars are left to find the answer. Emphasize that when we subtract, we are finding out how many things remain after some are taken away. The equation 5 – 2 equals 3 can be written on the board to illustrate the subtraction sentence. Encourage the students to create their own subtraction stories using toys or other familiar items to reinforce the concept.

Subtraction Game with Cubes – Let’s play a cube subtraction game! – Listen to the number I say – Take away that many cubes – Who can tell the answer first? | This interactive game is designed to help Pre-K students understand the concept of subtraction in a fun and engaging way. Start by giving each student a set of cubes (up to 10). Call out a number and instruct the students to remove that number of cubes from their set. The first student to correctly state how many cubes they have left wins that round. Repeat the game with different numbers to reinforce the concept. Possible variations of the activity could include: using different colored cubes for subtraction, pairing students to work together, or having students call out numbers for their peers to subtract. This hands-on activity not only teaches subtraction but also helps with number recognition and listening skills.

Class Activity: Cube Take Away! – Start with 10 cubes each – Take turns to remove cubes – Say a number and remove that many – Count the remaining cubes – How many cubes are left now? – Learn subtraction together | This interactive activity is designed to introduce the concept of subtraction to Pre-K students using a hands-on approach. Each student starts with 10 cubes, and they take turns removing a specified number of cubes. After each turn, the class counts the remaining cubes together, reinforcing the concept of subtraction as ‘taking away.’ This activity not only teaches basic subtraction but also encourages participation, turn-taking, and reinforces counting skills. Possible variations include: having students remove cubes based on different prompts, working in pairs, or challenging them to reach a specific number of cubes. The goal is to make subtraction tangible and fun.

Review Time: Learning Subtraction! – Subtraction means taking away – Like when we have 5 candies and eat 2, we have 3 left! – We use the minus sign (-) for subtraction – It looks like a small dash that tells us to take away – Subtract with fingers – Hold up 10 fingers and put down 2, how many are left? – Practice with real examples | This slide is a review of the basic concept of subtraction for Pre-K students. Start by explaining subtraction as the process of taking something away from a group, which results in fewer items in that group. Show the minus sign and ensure that students can recognize it as the symbol for subtraction. Demonstrate subtraction using fingers, which is a tangible way for young learners to understand the concept. Encourage students to practice with real objects like blocks or candies to solidify their understanding. The goal is to make them comfortable with the idea of ‘taking away’ and associating it with the subtraction process.

Goodbye and Great Job! – Fantastic job learning subtraction! – Subtraction means taking away – Like 5 cubes take away 2 leaves us 3 – Discover what’s left after taking away – Celebrate being great math helpers! – Give yourself a big cheer and a pat on the back! | This slide is a positive reinforcement to celebrate the students’ accomplishment in learning the basics of subtraction. It’s important to end the lesson on a high note, making sure the children understand that subtraction is simply the process of taking away from a group and seeing what remains. Use physical gestures like a pat on the back to make the celebration tangible for the children. Encourage them to continue practicing at home with their toys or snacks, reinforcing the concept in a fun and engaging way. This will help solidify their understanding and build a strong foundation for future math skills.
