Welcome to Subtraction! – Subtraction means taking away – If you have 4 apples and eat 1, you have 3 left! – Start with numbers up to 5 – Match pictures to sentences – See 5 ducks, 2 leave, how many are left? – Practice with fun activities – We’ll use toys and drawings to learn! | This slide introduces the concept of subtraction to Kindergarten students using simple language and relatable examples. Subtraction is explained as the process of taking away items from a group. The goal for the lesson is for students to be able to visually match subtraction sentences with corresponding pictures, which helps in understanding the concept of ‘taking away’. Activities can include using physical objects like toys or counters to represent the numbers in subtraction sentences, and drawing pictures to visualize the subtraction process. Encourage students to think of subtraction in terms of items they interact with daily, like snacks or toys, to make the concept more tangible.

What is Subtraction? – Subtraction means taking away – Like when we have 5 apples and eat 2, we have 3 left – Numbers get smaller when we subtract – If we start with 4 toys and give 1 away, we have 3 toys now – Let’s see subtraction in action! – Practice with real objects – Use toys or fingers to show subtraction | This slide introduces the concept of subtraction to Kindergarten students. Subtraction is explained as the process of taking away from a total number, which results in a smaller number. Use tangible examples like apples or toys to illustrate this point. Encourage the students to visualize the concept by using their fingers or classroom objects. For instance, if a student has 5 blocks and takes away 2, they can count how many blocks are left. This hands-on activity will help them understand subtraction in a concrete way. Prepare to demonstrate several examples with different numbers up to 5, and ensure that students can see the subtraction happening. The goal is for students to recognize that subtraction is simply removing some items from a group and counting what remains.

Learning Subtraction Sentences – Subtraction sentence parts – A subtraction sentence has a minuend, subtrahend, and difference. – Starting number explained – If we start with 5 blocks and take away 2, our first number is 5. – Taking away the second number – We remove the second number of items from our starting number. – Finding the remaining amount – After taking away, we count what’s left to find the answer. | This slide introduces the concept of subtraction sentences to Kindergarten students. Begin by explaining that a subtraction sentence is like a story that has a beginning (the first number), a middle (the second number we take away), and an end (the answer, which is how many are left). Use tangible examples like blocks or toys to illustrate this concept. For instance, if we have 5 apples and we eat 2, we are left with 3 apples. The subtraction sentence would be 5 – 2 = 3. Encourage the students to use their fingers or objects to practice creating their own subtraction sentences and finding the answers.

Matching Models to Subtraction Sentences – Pictures aid subtraction understanding – Visuals help us see what subtracting looks like – Pictures show items being removed – If we start with 5 apples and take 2 away, we see 3 apples left – Match pictures to subtraction sentences – Find the picture that shows the same number of items taken away as the sentence – Practice with examples up to 5 – Let’s try with numbers 0 to 5 to see how subtraction works | This slide introduces the concept of using visual aids to understand subtraction sentences. It’s important for students to recognize subtraction as the process of removing items and to be able to connect this action with written number sentences. By matching pictures that illustrate subtraction to the corresponding sentences, students will develop a concrete understanding of the concept. Use simple examples with numbers up to 5 to ensure that the content is age-appropriate for Kindergarten students. During the lesson, encourage students to discuss what they see in the pictures and how it relates to the subtraction sentences. Provide hands-on practice with physical objects or interactive digital activities to reinforce learning.

Let’s Practice Subtraction! – Start with 5 stars on the board – Show 2 stars fading away – Ask: What’s 5 minus 2? – Think: If 2 stars disappear, how many are left? – Reveal the answer: 5 – 2 = 3 – When we take 2 from 5, we’re left with 3 stars | This slide is an interactive class activity to help Kindergarten students understand subtraction up to 5. Display a picture with 5 stars and animate 2 stars fading away or being removed. Ask the students to observe and think about what subtraction sentence the picture represents. Guide them to understand that subtraction means taking away and help them visualize this concept. After a student volunteers the correct answer, reinforce the concept by explaining that when we subtract 2 from 5, we have 3 stars left. Encourage the students to use their fingers to count and subtract. This visual and participatory approach helps solidify the concept of subtraction in young learners.

Your Turn to Match! – Observe the picture carefully – Count the total items first – Start with counting all items before any are removed – How many items are taken away? – Look for the difference in the before and after pictures – Write the matching subtraction sentence – Use numbers to show how many are left, like 5 – 2 = 3 | This slide is an interactive activity for students to apply their understanding of subtraction. Display pictures that clearly show a group of items, and then some items being removed. Guide the students to first count the total number of items in the picture. Then, help them identify how many items are taken away by comparing the before and after scenarios. Finally, assist them in writing the subtraction sentence that represents what they see. For example, if there are 5 apples and 2 are taken away, the sentence would be 5 – 2 = 3. Encourage students to verbalize their thought process and provide assistance as needed. This activity will reinforce the concept of subtraction and the ability to translate visual information into mathematical sentences.

Class Activity: Subtraction Bingo – Let’s play Subtraction Bingo! – Match pictures to subtraction sentences – Look at the board, find the same picture on your card with a subtraction sentence – Find five correct matches in a row – Get your five matches vertically, horizontally, or diagonally – Win with answers up to 5 – Make sure your subtraction answers are 5 or less to win | This interactive game is designed to help Kindergarten students practice and reinforce their understanding of subtraction within 5. Set up the bingo game by providing each student with a bingo card that has different subtraction sentences up to 5. Display pictures that represent subtraction problems on the board. Guide the students to find the matching subtraction sentence on their bingo cards. The goal is to find five correct matches in a row, which can be vertical, horizontal, or diagonal. The first student to achieve this wins the game. Ensure that the students understand that all subtraction answers must be 5 or less. This activity not only makes learning subtraction fun but also encourages attention to detail and critical thinking.
