Welcome to Subtraction! – Greet our little mathematicians – Today’s lesson: taking away numbers – We’ll learn to ‘take away’ from a group – Subtraction is sharing with friends – Imagine you have 5 toys and give 2 to a friend, how many are left? – Visualize subtraction as giving – We’ll use pictures to help us see this | Begin the class with a warm welcome to set a friendly atmosphere. Explain that subtraction is a way of finding out how many things are left when we take some away. Use a relatable example, such as sharing toys, to illustrate the concept of subtraction in a way that resonates with their experiences. Encourage the children to visualize the act of giving away toys to friends and understanding that subtraction is simply determining what remains. Use props or visual aids to demonstrate subtraction with real objects, which can help them grasp the concept more concretely. The goal is to make subtraction feel like a natural and understandable part of their daily play.

What is Subtraction? – Subtraction means taking away – Find out how many are left – Like eating cookies and counting – If you have 5 cookies and eat 2, how many are left? – Subtraction is easy and fun! | This slide introduces the concept of subtraction to Kindergarten students in a simple and relatable way. Subtraction is explained as the process of taking away items from a group and finding out what remains. Use everyday examples like cookies on a plate to illustrate this point. If there were originally 5 cookies and 2 are eaten, ask the students how many cookies are left to help them understand the concept of subtraction. Emphasize that subtraction is a basic math skill that can be fun and is very useful. Encourage the students to think of other examples where they have taken things away and counted what is left to further solidify their understanding.

Subtracting with Pictures – Start with 5 apples – Imagine eating 2 apples – We had 5, but 2 are now in our tummies! – Cross out the 2 apples – Draw an ‘X’ on the 2 apples we ate – Count the apples left – Only 3 apples are left, that’s our answer! | This slide is designed to introduce the concept of subtraction to Kindergarten students using visual aids. Start by showing a picture of 5 apples. Explain that if we eat 2 of them, we can cross those out. Then, have the students count the remaining apples. This visual and interactive method helps young learners grasp the concept of taking away and finding what’s left. Encourage the students to draw their own pictures and cross out items to solve subtraction problems. This hands-on activity will make learning subtraction fun and memorable.

Subtracting Numbers Up to 10 – Learn to subtract with 1 to 10 – We’ll use numbers like 2 – 1, 5 – 3, and 10 – 6. – Use fingers to count and subtract – Hold up 7 fingers, put 2 down, and count what’s left. – Subtract small from big numbers – Remember, 8 – 3 works, but not 3 – 8. – Practice with examples – Try 4 – 1 and 9 – 5 with your classmates. | This slide introduces the concept of subtraction using numbers up to 10, which is a fundamental math skill for Kindergarten students. Start by explaining that subtraction means taking away and show how to use fingers to represent numbers and actions of taking away. Reinforce the concept that a larger number must be the one we start with when subtracting. Provide simple examples and encourage students to use their fingers to solve them, ensuring they understand the concept of ‘taking away’. Use objects like blocks or counters for a more tactile experience if needed.

Let’s Practice Subtracting! – Solve subtraction problems together – Example problem: 7 – 3 = ? – We have 7 apples, if we eat 3, how many are left? – Start with 7, take away 3 – Discover what number is left – After taking away, we count what’s left to find the answer | This slide is designed to introduce the concept of subtraction to Kindergarten students in a simple and interactive way. Start by explaining that subtraction means taking away some things from a group and then seeing how many are left. Use the example problem to illustrate this concept: if we have 7 items and we take away 3, we count the remaining items to find the answer. Encourage the students to use their fingers or objects like counters to physically remove items and count what’s left. This tactile approach helps solidify the concept of subtraction. Prepare to walk through several problems as a class, and ensure that each student is following along and engaging with the activity.

Subtraction is Fun! – Use toys to learn subtraction – If you have 5 blocks and give away 2, how many do you have left? – Subtraction games make learning fun – Games like ‘take away’ help us understand subtracting – Let’s play a subtraction game – We’ll play a game where we ‘take away’ items and count what’s left | This slide is designed to introduce Kindergarten students to the concept of subtraction in a playful and engaging manner. Using toys as a visual and physical aid helps children grasp the concept of ‘taking away’. Encourage them to use their own toys to practice subtracting at home. Incorporate interactive games during the lesson to reinforce the concept. For the in-class activity, prepare a simple subtraction game where students can participate and practice subtracting numbers up to 10. This could involve physical objects they can handle or a digital game projected on the screen. The goal is to make subtraction a fun and enjoyable experience, thereby fostering a positive attitude towards learning math.

Class Activity: Subtraction Bingo – Let’s play Subtraction Bingo! – Solve subtraction problems – Use numbers up to 10 to subtract – Cover the answer on your card – Win a sticker for covering all numbers! | This interactive activity is designed to help Kindergarten students practice subtraction with numbers up to 10 in a fun and engaging way. Prepare bingo cards with answers to simple subtraction problems. Guide the students through solving subtraction problems and then finding and covering the correct answers on their bingo cards. The first student to cover all their numbers calls out ‘Bingo!’ and wins a sticker. This game encourages quick thinking and reinforces the concept of subtraction. Possible variations of the activity could include playing in small groups, timed rounds, or having students create their own subtraction problems for peers to solve.
