Welcome to Subtraction! – Learning to take away numbers – Subtraction shows how many left – If you have 5 apples and eat 2, subtraction tells you 3 are left. – Using pictures to understand – Visual aids make it easier to see subtraction in action. – Practice with fun examples | This slide introduces first graders to the concept of subtraction as a means of finding out how many items are left after some are taken away. Emphasize that subtraction is simply ‘taking away’ and can be easily visualized with the help of pictures. Use everyday examples, like apples or toys, to make the concept relatable. Encourage the students to visualize the subtraction process by drawing or using objects. Plan a few simple subtraction problems using pictures that the students can solve together in class. This will help them grasp the concept of ‘how many are left’ in a fun and interactive way.

Understanding Subtraction – Subtraction means taking away – Finding out how many are left – If you have 5 apples and eat 2, how many do you have left? – Recognize the minus sign – – The minus sign tells us to subtract one number from another – Practice with subtraction pictures – Use pictures to solve subtraction problems, like 10 birds – 3 birds flying away | This slide introduces the basic concept of subtraction to first graders. Start by explaining that subtraction is simply the process of taking some away from a larger group. Use tangible examples, such as toys or snacks, to illustrate this point. Show the minus sign and ensure that students can recognize and understand its meaning in subtraction. Finally, incorporate visual aids, such as pictures or drawings, to help students visualize the subtraction process. For example, draw a group of 10 birds and then cross out 3 to show how many are left. Encourage students to draw their own pictures to solve subtraction problems.

Subtraction Story: Sharing Apples – Start with 5 apples – Give 2 apples to a friend – How many apples left? – Solve: 5 apples – 2 apples = 3 apples left | This slide introduces a simple subtraction word problem involving apples to help first graders visualize the concept of taking away. Begin by explaining the scenario where they have 5 apples and decide to give 2 away to a friend. Ask the students to visualize the apples and the act of giving them away. Then, pose the question of how many apples they have left to encourage them to think about the problem. Write down the subtraction equation on the board and solve it together, reinforcing the concept that subtraction means taking away. Encourage students to use their fingers or counters to represent the apples and physically remove 2 to find the answer. This hands-on approach helps solidify their understanding of subtraction.

Let’s Practice Subtraction with Balloons! – Start with 10 balloons – Imagine 3 balloons fly away – How many are left? – 10 balloons minus 3 balloons that flew away – Use fingers to subtract – Counting down from 10, put 3 fingers down | This slide is an interactive class activity designed to help first graders practice subtraction using visual aids and physical counting. Present a picture of 10 balloons and then visually demonstrate 3 balloons flying away. Encourage the students to use their fingers to count down from 10 as they subtract the 3 balloons that flew away. This tactile method supports their understanding of subtraction as ‘taking away’. After the activity, ask the students to share how many balloons they have left to ensure they’ve grasped the concept. Prepare to offer additional support to any student who may need it and praise their efforts to build confidence.

Your Turn to Try: Cookie Subtraction! – Start with 8 cookies – Eat 5 cookies – How many left? – Draw to subtract – Picture each cookie as you draw and cross out 5 | This slide is an interactive activity for students to apply their understanding of subtraction in a fun and relatable context. Provide students with a simple illustration of 8 cookies, and instruct them to cross out 5, visually representing the subtraction process. Encourage them to count the remaining cookies to find the answer. This exercise helps to reinforce the concept of ‘taking away’ in subtraction. For the activity, you can suggest students use real cookies, counters, or draw on paper. Offer additional similar problems with different numbers for more practice, and ensure to praise their efforts to build confidence.

Solving Subtraction Stories – Stories with numbers are fun – Pictures help us understand – Draw or use objects to visualize the problem – Read a story and find the answer – We’ll read aloud and subtract step by step – Practice makes us better | This slide introduces first graders to the concept of subtraction word problems. Emphasize that word problems are like little stories where we find and take away numbers to get an answer. Use pictures and physical objects to make the problems relatable and easier to visualize. Read a simple subtraction story as a class, and solve it together, ensuring to go through each step slowly. Encourage the students to practice with different stories to become more comfortable with subtraction. Provide several examples and guide them through the process of identifying the numbers involved and performing the subtraction.

Class Activity: Subtraction Skit – Act out a subtraction story – Students become ‘numbers’ – ‘Numbers’ get taken away – Count ‘numbers’ left at the end | This interactive class activity is designed to help first graders understand subtraction through a physical and visual representation. Assign roles to students to act as ‘numbers’ in a story. As the story progresses, some ‘number’ students will be ‘taken away’, simulating subtraction. The remaining ‘number’ students will then be counted, demonstrating the result of the subtraction. This kinesthetic approach caters to different learning styles and makes the concept of subtraction tangible. Possible scenarios for the skit could include: a picnic with a certain number of apples that are eaten, a number of birds on a tree with some flying away, or a set of balloons with some popping. Ensure that the scenarios are simple and relatable, and encourage students to engage with the story actively.

Subtraction: How Many Left? – Subtraction shows what’s left – Pictures make subtraction fun – Count objects in pictures to subtract – Stories help us learn to subtract – Solve problems with characters and situations – Practice makes perfect! | This slide wraps up the lesson on subtraction word problems with pictures. Emphasize to the students that subtraction is a way to find out how many items are left after some are taken away. Reinforce the concept by using visual aids like pictures, which can make learning more engaging for first graders. Additionally, incorporating stories into subtraction problems helps students relate to the material and understand it in the context of real-life situations. Encourage the students to practice with their subtraction worksheets at home to reinforce what they’ve learned today. Remember to praise their efforts and progress to build their confidence in their math skills.
