Welcome to Subtraction! – Greetings little mathematicians! – Learn to take away with subtraction – If you have 4 apples and eat 1, how many do you have left? – Subtraction shows how many left – Subtracting is like removing items from a group – Let’s practice with numbers up to 5 – We’ll use toys or fingers to practice subtracting | This slide introduces Pre-K students to the concept of subtraction as a means of determining how many items remain after some have been taken away. Emphasize that subtraction is a simple process of ‘taking away’ and can be practiced with everyday items. Encourage the children to use their fingers or classroom objects to visualize the subtraction process. For example, if they start with 5 blocks and take 2 away, they can count how many blocks are left. This hands-on approach will help them grasp the concept of subtraction up to 5. Prepare to demonstrate with real objects and guide them through several examples, ensuring they understand the concept before moving on to practice problems.

Understanding Subtraction: Taking Away – Subtraction means taking away – Like when we have 5 apples and eat 2, we have 3 left – Start with a number – Take some away – If we have 4 blocks and give 1 to a friend, how many do we have? – Count what’s left – After taking away, we count the remaining items | This slide introduces the basic concept of subtraction to Pre-K students. Subtraction is explained as the process of taking away from a total amount. Start by showing a group of objects, such as blocks or toys, and physically remove some to demonstrate ‘taking away.’ Encourage the students to visualize the concept by using real-life examples, like sharing snacks or toys. After removing some items, guide the students to count the remaining items to find out ‘how many are left.’ Reinforce the concept by using simple language and tangible examples that are relatable to their everyday experiences. The goal is to make sure students can recognize subtraction as an action of removing and can practice counting the leftovers to find the answer.

Understanding Subtraction Sentences – Subtraction sentence structure – A subtraction sentence includes numbers and a minus sign (-). – Meaning of subtraction – It shows how many items are taken away from a group. – Example: 5 – 2 = 3 – Starting with 5 items, if we take away 2, we’re left with 3 items. | 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 items from a group and finding out how many are left. Use physical objects like blocks or counters to visually demonstrate the subtraction process. For example, start with 5 blocks, remove 2, and count the remaining blocks to show that 3 are left. This visual and hands-on approach helps young learners grasp the concept of subtraction in a concrete way. Encourage the students to create their own subtraction sentences using objects from the classroom.

Let’s Practice Subtraction Together! – Start with 5 fingers raised – Fold down 2 fingers – Count the fingers still raised – How many fingers are still up? – Understand 5 minus 2 equals 3 – 5 fingers – 2 fingers = 3 fingers | This slide is an interactive class activity to help Pre-K students understand the concept of subtraction using their fingers. Start by asking the students to hold up all 5 fingers, which represents the total amount. Then, instruct them to fold down 2 fingers, which represents the amount being taken away. Ask the students to count how many fingers they have left raised. This will help them visually and physically understand that when we subtract 2 from 5, we are left with 3. Reinforce the concept by repeating the activity with different numbers of fingers folded down. Encourage the students to articulate the subtraction sentence: ‘5 minus 2 equals 3’. This hands-on approach makes learning subtraction tangible and understandable for young learners.

Subtraction with Objects: Blocks! – Start with 5 blocks – Move 2 blocks away – How many blocks left? – If we take 2 from 5, what do we have? – Count remaining blocks – After removing 2, count what’s left. | This slide introduces the concept of subtraction to Pre-K students using a tangible method with blocks. Start by counting out 5 blocks with the class, ensuring each student is engaged and following along. Then, physically remove 2 blocks from the group and ask the students how many blocks are left. Encourage the students to count the remaining blocks aloud together to find the answer. This hands-on activity helps solidify the concept of ‘taking away’ in subtraction. For the next class, prepare similar activities with different numbers of blocks up to 5 to reinforce the concept. Remember to keep the activity fun and interactive to maintain the children’s interest.

Understanding Subtraction with Models – Subtraction models with pictures – Pictures help us see how we subtract items. – Total, taken away part, and remainder – Start with total items, remove some, count what’s left. – Analyze model for subtraction sentence – Match the model to the subtraction sentence it shows. | This slide introduces the concept of using visual models to understand subtraction. The model will typically consist of a group of objects that represent the total number. Students will visually see some objects being taken away, which helps them grasp the concept of subtraction by identifying the remaining objects. It’s crucial to guide the students step by step: start with counting the total number of objects, identify the number of objects to subtract, and then count the remaining objects to find the answer. This visual and hands-on approach is particularly effective for Pre-K students as it aligns with their developmental stage and learning style. Encourage the students to create their own models using classroom materials like blocks or counters to reinforce the concept.

Class Activity: Subtraction Skit – Act out subtraction stories – Be ‘apples’ in our tree – Some ‘apples’ will ‘fall down’ – Count ‘apples’ left in the ‘tree’ | This interactive class activity is designed to help Pre-K students understand the concept of subtraction in a fun and engaging way. Set up an area to represent a tree and assign a few students to be ‘apples’ in the tree. As the ‘apples’ pretend to fall down, the rest of the class counts how many are left. This visual and physical representation of subtraction will help students grasp the concept of ‘taking away’. Possible variations of the activity could include using different objects or scenarios, such as ‘leaves’ falling from a ‘tree’ or ‘toys’ being put away. The key is to keep the numbers within 5 to align with the lesson’s objective. Encourage students to use their fingers to count and verify the number of ‘apples’ remaining. This activity not only teaches subtraction but also reinforces counting skills.

Becoming a Subtraction Star! – Congratulations on learning subtraction! – Subtraction means taking away – Like 5 apples minus 2 is 3 apples left – Practice subtraction with toys – Use your toys to subtract, like 4 cars minus 1 car – Keep practicing to be a star! | This slide is meant to celebrate the students’ accomplishment in learning the basics of subtraction. It’s important to reinforce the concept that subtraction is the process of taking away from a group. Encourage the students to practice with tangible items like toys to solidify their understanding. Remind them that subtraction is a skill they can improve with practice, just like a star athlete or performer. Provide examples of how they can practice at home, such as setting up a group of toys and removing some, then counting how many are left. Celebrate their progress and encourage a positive attitude towards continued learning and practice.
