Your next great Lessn starts here.

Welcome to Subtraction! – Greetings, little mathematicians! – Subtraction means taking away – If you have 5 apples and eat 2, subtraction helps you find how many are left. – Subtraction shows us what’s left – Imagine having 10 balloons and 3 fly away. How many do you have now? – Let’s practice with numbers up to 10 | 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 like taking something away, such as when they eat some of their snacks and have fewer left. Use tangible examples like toys or snacks to illustrate the concept of ‘how many are left’. Encourage the children to use their fingers or objects to practice subtracting numbers up to 10. The goal is to make them comfortable with the idea of ‘taking away’ in a playful and engaging manner. Prepare to demonstrate with real objects or visual aids to help them visualize the subtraction process.

Understanding Subtraction: Taking Away – Subtraction means taking away – Imagine you have 5 apples and give away 2, now you have 3. – Find out how many left – If you start with 10 fingers and hide 4, you see 6 fingers left. – Like eating cookies – Think of having 4 cookies; if you eat 1, how many are left? – Fewer items remain – After taking some away, count what’s left. | This slide introduces the concept of subtraction to Pre-K students by relating it to a tangible experience like eating cookies. Start by explaining that subtraction is simply the process of taking some things away from a group and then seeing how many are left. Use real-life examples that are relatable to the children, such as playing with toys or sharing snacks. Encourage the students to visualize the process by using their fingers to represent the items being subtracted. Reinforce the concept by having them practice with physical objects in the classroom, such as blocks or counters, to solidify their understanding of ‘taking away’ and ‘how many are left’.

Understanding Subtraction Sentences – Subtraction sentence structure – A subtraction sentence includes numbers and a minus sign (-). – Example: 5 – 2 = 3 – Taking 2 away from 5 leaves us with 3. – ‘Difference’ in subtraction – The result of subtraction is called the ‘difference’. | This slide introduces the concept of subtraction sentences to Pre-K students. Begin by explaining that a subtraction sentence is a way to show taking away using numbers and a minus sign. Use simple examples like taking away blocks or toys to visually demonstrate the concept. Emphasize the term ‘difference’ as the name for the answer in a subtraction sentence. Encourage students to use their fingers or objects to practice subtracting numbers up to 10 and finding the difference. This hands-on approach helps solidify their understanding of basic subtraction.

Let’s Practice Subtraction Together! – Start with 10 blocks – Take away 4 blocks – Count remaining blocks – How many blocks are left now? – Find the result of 10 – 4 – 10 minus 4 equals how many? | This slide is designed to be an interactive class activity to help Pre-K students understand the concept of subtraction by using physical blocks. Start by showing students 10 blocks, then physically remove 4 and ask the students to count the remaining blocks. This visual and tactile method helps them grasp the concept of ‘taking away’. After counting the remaining blocks, guide them to understand that 10 minus 4 equals the number of blocks they have counted. Encourage the students to participate in the counting and to verbalize the subtraction sentence. Prepare to have enough blocks for each student or group of students to perform the activity, and consider having additional subtraction examples ready if time allows.

Using Models to Subtract – Use fingers or counters to subtract – Like subtracting 2 apples from 5 apples – Take away counters to find difference – If you have 5 toys and give away 2, how many do you have left? – Count what’s left after subtraction – After giving 2 toys away, we count the remaining toys – Visualize subtraction with models | This slide introduces the concept of subtraction using tangible models, which is a method suitable for Pre-K students. Demonstrate subtraction by using physical objects like counters or fingers, which helps children visualize the process. For example, if we start with 5 counters and remove 2, we can count the remaining 3 to find the difference. Encourage the students to use their fingers or objects in the classroom to practice subtracting numbers up to 10. This hands-on activity will help them understand the concept of ‘taking away’ in a concrete way. Prepare to guide them through several examples, and ensure they are comfortable with counting the remaining objects after some have been taken away.

Your Turn to Subtract! – Now it’s your turn to practice – Use counters for subtraction – Counters can be small objects like beans or buttons – Solve the given subtraction sentence – I’ll say ‘5 – 2’, take 5 counters and remove 2 – Remember to count carefully | This slide is an interactive activity for the students to practice subtraction with physical counters. Provide each student with a set of counters (like beans, buttons, or blocks) and give them simple subtraction sentences to solve, such as ‘5 – 2’. Encourage them to lay out the total number of counters and then physically remove the number they are subtracting. This hands-on approach helps them visualize the subtraction process. Monitor the students as they work, offering help as needed. Possible variations of the activity could include using different items as counters, solving subtraction problems in pairs, or creating a subtraction song to sing along as they count.

Subtraction Story Time – Listen to a subtraction story – Notice items left after taking away – If 5 apples and 2 are taken away, how many are left? – Solve subtraction sentences together – We’ll use the story’s examples to practice – Understand subtraction through story – Stories help visualize the subtraction concept | This slide introduces the concept of subtraction to Pre-K students through storytelling, which is an effective method for young learners to grasp mathematical concepts. As you narrate the story, emphasize the subtraction events, such as items being taken away, and encourage students to visualize and count the remaining items. After the story, work through the subtraction sentences that were presented in the narrative, solving them as a class. This interactive approach helps students understand subtraction as ‘taking away’ in a fun and engaging manner. Prepare a simple story with clear subtraction examples and ensure to have props or visuals to aid in storytelling. Encourage participation and ask questions to ensure comprehension.

Class Activity: Subtraction with Snacks – Start with a snack count – Eat a few snacks together – Count the remaining snacks – Understand subtraction is fun Subtraction means taking away; we eat snacks and see how many are left. | This activity is designed to introduce the concept of subtraction to Pre-K students in a tangible and engaging way. Distribute an equal number of snacks to each student, ensuring the total does not exceed 10. Guide the class to eat a predetermined number of snacks, then count how many are left. This hands-on experience helps them visualize the subtraction process. As they eat and subtract, they’ll begin to understand that subtraction represents taking away from a group. Have additional snack-based subtraction scenarios ready for students who grasp the concept quickly, and be prepared to assist those who need more guidance. Remember to check for any food allergies before the activity.

Review and Goodbye: Subtraction Fun! – Recap: What is subtraction? – Subtraction means taking away from a number. – Show subtraction with fingers – Use fingers to make a ‘take away’ sentence, like 10 minus 2. – Celebrate our learning today – Looking forward to next time! | As we conclude today’s lesson, we’ll revisit the concept of subtraction, emphasizing that it’s the process of taking away from a group. Encourage the children to use their fingers to visually represent subtraction problems, such as starting with 10 fingers up and putting 2 down to show 10-2. Praise their efforts and progress in understanding subtraction, and express excitement for the next lesson to build a positive and encouraging learning environment. For the next class, consider preparing a set of subtraction flashcards or interactive games to reinforce today’s concepts.
