Welcome to Subtraction! – Greetings, young mathematicians! – Subtraction means taking away – If you have 5 apples and eat 2, subtraction helps you find how many are left. – It shows us what’s left over – For example, 10 – 3 shows us 7 are left. – Let’s practice with numbers up to 10 | This slide is designed to introduce Kindergarten students to the concept of subtraction as a means of determining how many items remain after some have been taken away. Start by greeting the students warmly to create an inviting learning environment. Explain subtraction in simple terms, using real-life scenarios such as having a certain number of items and then taking some away. Use props or visual aids to demonstrate subtraction with small numbers, ensuring the concept is clear. Encourage the students to think of subtraction as a fun activity rather than a challenge. Prepare to guide them through hands-on practice with numbers up to 10, using objects like blocks or counters to make the learning experience tangible and engaging.

Understanding Subtraction: Taking Away – Subtraction means taking away – Find out how many are left – If we start with 5 blocks and take away 2, we have 3 left. – It’s like eating cookies – Imagine having 5 cookies and eating 2, how many do you have now? – How many cookies are left? | This slide introduces the concept of subtraction to Kindergarten students by relating it to a tangible experience such as eating cookies. Start by explaining that subtraction is simply the process of taking some away from a larger group and finding out what’s left. Use physical props like blocks or cookies to visually demonstrate subtraction. For example, show 5 blocks, remove 2, and ask the students how many are left to solidify the concept. Encourage the students to think of subtraction as a fun activity, like eating cookies, to create a positive and engaging learning environment. The goal is for students to understand subtraction as a means of finding out the remaining quantity after some has been taken away.

Learning Subtraction Symbols – Minus sign (-) for subtraction – The minus sign takes away numbers. – Equals sign (=) shows the answer – The equals sign means ‘is the same as’. – Example: 5 – 2 = 3 – From 5 apples, if we take 2 away, we have 3 apples left. | This slide introduces the basic symbols used in subtraction: the minus sign and the equals sign. Explain that the minus sign is used to show that we are taking some amount away from a larger amount. The equals sign is used to show the result of the subtraction. Use a simple and relatable example, such as subtracting apples, to illustrate the concept. Have physical objects available to demonstrate subtraction visually. Encourage the students to use their fingers or objects to practice subtracting numbers up to 10. Reinforce the concept by asking students to come up with their own subtraction examples using items in the classroom.

Let’s Try Subtraction Together! – Start with 5 apples – Take away 2 apples – How many apples left? – Count to find the answer – After taking 2 away from 5, we count the rest to get 3 apples. | This slide is an interactive class activity designed to introduce students to the concept of subtraction by using a relatable example of apples. Start by showing the students 5 apples (either real, drawn, or using manipulatives). Then, physically remove 2 apples from the group and ask the students to observe what happens. Guide them to count the remaining apples to find the answer. Reinforce the subtraction sentence: 5 apples minus 2 apples equals 3 apples. Encourage the students to use their fingers or other classroom objects to practice this subtraction. This hands-on activity will help them understand subtraction as ‘taking away’ in a tangible and visual way.

Complete the Subtraction Sentence – Use pictures to subtract – Count crossed out items – If 5 apples and 2 are crossed out, how many are left? – Count what’s left – After counting crossed out, count remaining items – Fill in the blanks – Example: 5 apples – 2 apples = 3 apples | This slide is designed to introduce Kindergarten students to the concept of subtraction using visual aids. By counting items that are crossed out in a picture, students can visually understand what it means to subtract. They will then count the remaining items to determine the answer and complete the subtraction sentence. This hands-on activity helps to solidify the concept of ‘taking away’ in a fun and engaging way. For the activity, provide various pictures with different items and numbers for the students to practice. Encourage them to use their fingers or counters to help in the counting process. The goal is for students to become comfortable with basic subtraction up to 10.

Practice Time: Subtraction with Pictures – Try subtraction problems now – Use pictures for help – Look at the images and take away the number of items as instructed – Count each item carefully – Make sure to count each item one by one – Show your answers to the class | This slide is designed to engage Kindergarten students in a hands-on subtraction activity. Provide them with pictures that clearly show groups of items up to 10, and ask them to subtract a certain number from these groups. Encourage them to point and count each item aloud as they subtract to ensure accuracy. After completing the problems, students should be prepared to present their answers and explain how they solved each problem. Possible activities include using physical objects like blocks or counters, drawing on a whiteboard, or interactive digital exercises. The goal is to reinforce the concept of taking away and understanding subtraction as a process.

Subtraction Game Time! – Play a subtraction game – Take turns with friends – Remove objects and solve – If you have 5 blocks and take 2 away, how many are left? – Practice makes perfect | This slide introduces a fun and interactive subtraction game for the students. The game is designed to help Kindergarten students practice and improve their subtraction skills with numbers up to 10. Set up a circle and give each student a small number of objects like blocks or counters. As they take turns, each student will remove a certain number of objects and then solve the subtraction problem that results. For example, if a student has 5 blocks and takes away 2, they solve 5 – 2 to find out they have 3 blocks left. Encourage students to use their fingers or the objects to count and find the answer. Possible activities include: 1) Subtraction with toy animals, 2) ‘Magic Number’ where one student hides objects and others guess the subtraction, 3) ‘Subtraction Storytime’ where students create stories around the objects being taken away, and 4) ‘Countdown’ where students start with 10 objects and take turns subtracting until they reach zero. This hands-on experience will reinforce their understanding of subtraction as ‘taking away’.

Class Activity: Subtraction with Blocks – Start with 10 blocks each – Remove a few blocks – Take away 1, 2, or more and see what happens – Ask a friend to count the rest – How many blocks are left? – This is the answer to your subtraction problem | This activity is designed to help Kindergarten students understand the concept of subtraction in a hands-on way. Each student will start with a set of 10 blocks, which represents the total amount. They will then remove a certain number of blocks, which represents the amount being subtracted. They will ask a classmate to count how many blocks are left, which will give them the result of the subtraction. Teachers should circulate the room to assist and ensure understanding. Possible variations of the activity could include: using different colored blocks to represent different numbers, having students record their subtraction sentences on paper, or pairing students up to solve prepared subtraction problems.

Review and Goodbye! – Subtraction means taking away – Like 5 apples – 2 apples = 3 apples left – How many are left after subtraction – If you have 4 toys and give 1 away, you have 3 toys now – Practice makes perfect – Excited to see you again! | This slide is meant to wrap up the lesson on subtraction by reinforcing the concept that subtraction is the process of taking away from a group and finding out what remains. Use examples like apples or toys to make it relatable for the students. Acknowledge their hard work during the lesson and encourage them to keep practicing at home. Let them know that you’re looking forward to seeing their progress in the next class. This positive reinforcement helps build their confidence and excitement about learning math.
