Welcome to Subtraction! – Greetings little mathematicians! – Learn to take away using pictures – Pictures help us understand subtraction – Subtraction is sharing toys – If you have 5 blocks and give 2 away, how many do you have? – Visualize ‘less’ with images – See how a group of items becomes smaller | This slide introduces Pre-K students to the concept of subtraction in a fun and relatable way. Start by greeting the students warmly to capture their attention. Explain that subtraction is simply the process of taking away items from a group, and we can use pictures to help us understand this concept. Compare subtraction to the act of sharing toys with friends to make it more relatable. For example, if a student has a certain number of toys and they give some away, they are practicing subtraction. Use visual aids like images of toys or blocks to show subtraction in action. Encourage the students to visualize the process of a group of items becoming smaller as things are taken away. The goal is to make subtraction tangible and less abstract by using real-world examples that resonate with their experiences.

What is Subtraction? – Subtraction means taking away – Find out how many are left – Like eating cookies from a plate – Imagine you have 5 cookies and eat 2, how many do you have now? – See how many cookies are left – After eating 2 cookies, you’ll have 3 left! | This slide introduces the concept of subtraction to Pre-K students in a very relatable and tangible way. Subtraction is explained as the process of taking something away and then seeing what remains. Use everyday examples like cookies on a plate to illustrate this point. If you start with a certain number of cookies and eat some, you can count how many are left to find the answer. This helps children visualize and understand subtraction as something they experience in daily life. During the class, you can use real cookies, pictures of cookies, or other items to demonstrate subtraction in a fun and engaging way. Encourage the children to participate by asking them subtraction questions based on the examples you provide.

Subtracting with Pictures: Apples – Pictures help us subtract – Count starting apples – If we have 10 apples, let’s count them together. – Eat and cross out apples – Imagine eating 2 apples, now cross out 2 apples. – Count apples left over – How many apples do we have now? Let’s count again. | This slide introduces the concept of subtraction to Pre-K students using a relatable and visual method: subtracting with pictures. Start by explaining that pictures can make it easier to see how subtraction works. Have a picture of apples (up to 10) and ask the students to count them aloud. Then, tell a story where some apples are eaten (e.g., 2 apples), and show the apples being crossed out on the picture. Finally, ask the students to count the remaining apples. This interactive approach helps students understand subtraction as ‘taking away’ in a tangible and engaging way. Encourage the students to visualize the process and assist them in counting the remaining items. This activity can be repeated with different numbers of apples to reinforce the concept.

Let’s Subtract Stars Together! – Start with 5 stars – Imagine 2 stars fall down – Cross out 2 stars – Just like erasing 2 stars from the sky – Count the remaining stars – How many stars can we see now? | This slide is an interactive class activity designed to teach Pre-K students the concept of subtraction using visual aids. Start by showing a picture of 5 stars. Guide the students to visualize 2 stars falling from the sky, which introduces the concept of subtraction. Then, demonstrate crossing out 2 stars on the picture, which will help them understand that subtraction means taking away. Finally, ask the students to count the stars that are not crossed out. This activity helps students to visually grasp the concept of subtraction by physically seeing the number of items reduce. Encourage the students to use their fingers to count and ensure everyone participates. Possible variations of the activity could include using different objects, such as apples or balls, and varying the numbers to subtract.

Your Turn to Subtract with Balloons! – Start with 10 balloons – Subtract popped balloons – If 3 balloons pop, hold up 10 fingers and put 3 down – Use fingers to count – Find remaining balloons – How many fingers are still up? That s how many are left! | This slide is an interactive activity for Pre-K students to practice subtraction using a fun and relatable scenario with balloons. Encourage the children to imagine having 10 balloons and then physically use their fingers to represent the balloons popping. This hands-on approach helps them visualize the subtraction process. As they put fingers down for each ‘popped’ balloon, they can easily see how many are left. Prepare to guide them through the activity, ensuring they understand the concept of ‘taking away’ and counting the remaining items. Offer various scenarios (e.g., 2 balloons pop, 4 balloons pop) to practice different subtraction problems. Praise their efforts to build confidence in their subtraction skills.

Picnic Subtraction Story – Start with 10 sandwiches – Imagine eating some sandwiches – How many do we eat at the picnic? – Draw and cross out eaten ones – Use drawing to visualize subtraction – Count how many are left – Subtract to find remaining sandwiches | This slide introduces a subtraction story to help Pre-K students understand the concept of taking away using a familiar scenario: a picnic. Start with 10 sandwiches, and ask the students to imagine they eat some, then have them draw the sandwiches and cross out the ones they pretend to eat. This visual and interactive approach helps them grasp subtraction as ‘taking away.’ Encourage the students to count the remaining sandwiches to find the answer. This activity can be done with actual objects or drawn on paper. It’s a fun way to introduce subtraction within 10 and helps to develop early math skills.

Class Activity: Subtraction Art – Receive a subtraction worksheet – Pictures represent numbers to subtract – Each picture stands for one unit – Subtract numbers by coloring – Color over pictures to subtract them – Show your completed art | This activity is designed to help Pre-K students understand subtraction in a visual and interactive way. Each student will receive a worksheet with a set of pictures. These pictures will represent the numbers they need to subtract. For example, if there are 5 apples and they need to subtract 2, they will color over 2 apples to show the subtraction. This hands-on activity not only makes learning subtraction fun but also reinforces the concept through art. Teachers should walk around the classroom to assist any student who may be struggling and to ensure that the students are subtracting the correct number of items. Possible variations of the activity could include using stickers to subtract from a number or having different coloring sheets for different subtraction problems.

Review and Goodbye: Subtraction Fun! – Excellent work with picture subtraction! – Subtraction means taking away – Like when we have 5 apples and eat 2, we have 3 left. – Practice subtraction with your worksheet – Try the exercises at home to become a subtraction star! – Show your family what you’ve learned! | Today, we’ve learned how to subtract using pictures, which helps us visualize the concept of taking away. Reinforce the idea that subtraction is simply removing some items from a group. Encourage the children to practice with their worksheets at home to reinforce what they’ve learned. Remind them to share their new skills with their family, which will help them feel proud of their learning and understand the practical use of subtraction in everyday life. Great job, everyone! Keep practicing and you’ll be subtraction experts in no time!
