Welcome to Subtraction! – Good morning, class! – Today we learn to take away numbers – Subtraction shows how many are left – Practice subtracting 6 from numbers up to 20 – Examples: 10 – 6 = 4, 15 – 6 = 9 | Greet the students warmly to create a welcoming learning environment. Introduce the concept of subtraction as a method of ‘taking away’ and explain that it helps us figure out the number of items remaining. Use simple and relatable examples, such as subtracting candies or toys, to illustrate the concept. For the activity, provide various numbers up to 20 and guide the students to subtract 6 from them. Encourage the students to use physical objects like counters or drawings to visualize the subtraction process. The goal is to ensure students understand the basic concept of subtraction and can confidently subtract the number 6 from other numbers up to 20.

Understanding Subtraction: Taking Away – Subtraction means taking away – Find out how many are left – Imagine 6 apples, give 1 away – If you had 6 apples and gave 1 to a friend, you subtract 1 from 6. – How many apples are left? – It’s like a mini-story to solve with numbers! | This slide introduces the concept of subtraction to first graders by relating it to a tangible example with apples. Subtraction is explained as the process of taking something away to see what remains. Use real apples or a visual aid to demonstrate subtraction, showing that when one is taken away, the total number decreases. Encourage the students to visualize the scenario and use their fingers or objects to count and subtract. Ask them to think of other examples where they have or could give something away and figure out how many they have left. This will help them understand the concept of subtraction in a fun and interactive way.

Subtracting 6 from Numbers – Practice subtracting 6 – Use fingers, objects, or number line – Counting down from a number, taking away 6 – Example with 10 blocks – Start with 10, remove 6, count what’s left – How many blocks are left? – It’s a subtraction problem: 10 – 6 equals? | This slide is aimed at helping first graders understand the concept of subtraction by taking away 6 from various numbers. Encourage the students to use tangible methods like their fingers, physical objects like blocks, or visual aids like a number line to subtract. For example, if a student starts with 10 blocks and removes 6, they can count the remaining blocks to find the answer. This hands-on approach helps solidify the concept of subtraction. During the class, walk through several examples together and then let the students try on their own. Provide guidance and ensure they understand that subtraction is the process of taking away from a total amount.

Let’s Subtract 6 Together! – Use counters to subtract 6 – Example: 8 – 6 = ? – Start with 8, remove 6, how many now? – Count 8 counters – Take 6 away, count what’s left – After removing 6, we have 2 counters left | This slide is designed to introduce first-grade students to the concept of subtraction by taking away 6 from a given number. Using physical counters will help them visualize the subtraction process. Start by counting out 8 counters with the students, then physically remove 6 counters while counting backwards. This will help them see that 8 minus 6 leaves 2 counters. Encourage the students to use their fingers if they don’t have counters. Repeat this activity with different numbers to ensure that the concept is understood. The goal is for students to become comfortable with subtracting 6 from numbers up to 20.

Subtracting 6 – Practice Time – Now let’s practice subtracting 6 – Remember to count backwards carefully – Solve together: 9 – 6 = ? – What number do you get if you take away 6 from 9? – Solve together: 7 – 6 = ?, 12 – 6 = ? – Find the answers by counting back 6 from 7 and 12 | This slide is designed to engage first-grade students in practicing the concept of subtracting 6 from various numbers. Encourage the students to use their fingers or counters to help them count backwards from the given number. As they solve 9 – 6, 7 – 6, and 12 – 6, remind them to start from the larger number and count back six steps to find the answer. Reinforce the concept by working through these problems as a class, and then allow the students to try similar problems on their own or in small groups. Provide immediate feedback and praise to build their confidence. For the teacher’s reference, the answers are: 9 – 6 = 3, 7 – 6 = 1, and 12 – 6 = 6.

Subtraction Story: Taking Away 6 – Read a subtraction story together – Characters remove 6 items – If a character has 10 apples and gives away 6, how many are left? – Count how many items are left – Use fingers or objects to help count the remaining items – Understand subtraction with 6 – Subtraction means taking away from a group | This slide introduces a story-based approach to teaching subtraction, specifically taking away 6 from a given number. The story will involve characters who have a certain number of items and then give away 6 of them. As the story progresses, pause to ask the students how many items are left each time. Encourage them to use their fingers or classroom objects to physically represent the items being taken away, which will help them visualize the subtraction process. Reinforce the concept that subtraction is the process of removing items from a group and finding out what’s left. The goal is for students to become comfortable with subtracting the number 6 from various totals up to 20.

Class Activity: Subtraction Scavenger Hunt – Let’s explore and find items – Subtract 6 items from your group – How many items are left? – Share your findings with the class | This interactive activity is designed to help first graders practice subtracting 6 in a fun and engaging way. Set up various groups of items around the classroom beforehand, ensuring each group has more than 6 items. Students will walk around the room and choose a group. They will then physically remove 6 items from their chosen group and count how many are left. Afterward, they will present their findings to the class, reinforcing their subtraction skills and ability to communicate their mathematical thinking. Possible variations of the activity could include using different items, pairing students to work in teams, or timing the activity to add an element of excitement.

Review and Goodbye! – Recap: Subtracting 6 – We learned how to take away 6 from numbers up to 20. – Subtraction in daily life – Maybe when you re sharing treats or toys with friends! – Celebrating our learning – Looking forward to next class | As we wrap up today’s lesson, let’s review the key points about subtracting 6 from various numbers. Encourage the children to think of times when they have used or could use subtraction in their daily lives, such as when sharing or when playing games. Praise their efforts and progress in today’s class to boost their confidence and interest in math. Let them know you’re excited to see them in the next class and continue the learning journey together. Prepare a few examples of subtraction used in everyday scenarios to share if the students need help brainstorming.
