Welcome to Addition! – Learning to add things together – Why addition is helpful – Addition combines numbers, making counting quicker – Writing addition sentences – We use symbols like ‘+’ and ‘=’ to write these sentences – Practice with sums up to 10 – Let’s add objects to reach a total of 10 | This slide introduces first graders to the concept of addition, which is a fundamental math skill. Start by explaining that addition is a way of putting things together to find out how many there are in total. Emphasize how addition can make counting faster than counting one by one. Show them the symbols used in addition sentences, such as the plus sign (+) and the equals sign (=). Use visual aids like pictures of objects that add up to 10 to help them understand. For example, show a picture with 4 apples and 6 oranges, and write the addition sentence 4 + 6 = 10. Encourage the students to practice with different combinations of numbers that add up to 10. This will help them become familiar with writing addition sentences and understanding the concept of sums.

What is Addition? – Addition combines numbers – Like adding blocks together – Adding makes numbers bigger – If you have 3 apples and get 2 more, now you have 5! – The ‘+’ sign means add – It’s like saying ‘and’ with numbers – Practice with sums up to 10 | This slide introduces the concept of addition to first graders. Start by explaining that addition is like combining things together, such as blocks or apples, to have more than you started with. Emphasize that when we add, the total number of items increases, making the number bigger. Show the ‘+’ sign and explain that it’s the symbol we use when we want to add numbers together. It’s like saying ‘and’ between numbers. For example, 2 + 3 is like saying ‘2 and 3’. Finish by encouraging students to practice adding numbers together with sums up to 10, using objects like toys or fingers to help them visualize the concept. This hands-on approach will help solidify their understanding of addition.

Let’s Count Together! – Count objects in the picture – Find the total number – Understand ‘sum’ in addition – ‘Sum’ is the total when we add together – Write the addition sentence – Example: 3 apples + 2 apples = 5 apples | This slide is aimed at helping first graders understand the concept of addition by visually counting objects in a picture and then writing the corresponding addition sentence. Start by showing a picture with a certain number of objects, up to 10. Ask the students to count the objects and then guide them to understand that the total number they’ve counted is called the ‘sum’. Explain that when we add two groups of objects together, we get this sum. Finally, demonstrate how to write the addition sentence that matches the picture. For example, if there are 3 apples and 2 more apples in the picture, the addition sentence is 3 + 2 = 5. Encourage the students to practice with different pictures and sums up to 10.

Writing Addition Sentences – What is an addition sentence? – It includes numbers, a plus sign, and an equal sign. – Example: 2 + 3 = 5 – This shows us adding 2 and 3 makes 5. – ‘Addends’ are numbers we add – In 2 + 3 = 5, 2 and 3 are addends. – ‘Sum’ is the answer to addition – In 2 + 3 = 5, 5 is the sum. | This slide introduces the concept of writing addition sentences to first graders. Start by explaining that an addition sentence is a way to show how two or more numbers come together to make a new number. Use simple examples with sums up to 10 to illustrate the concept. Clarify the terms ‘addends’ and ‘sum’ with visual aids like pictures or objects that students can count. Encourage students to create their own addition sentences using items in the classroom or from a picture. This foundational understanding will help them grasp the basic operation of addition.

Addition with Pictures: Sums Up to 10 – Count items in each picture group – Write the number for each group – Use plus and equal signs – For example, 3 apples + 2 apples = 5 apples – Find the total sum up to 10 – Ensure the total does not exceed 10 | This slide is aimed at helping first-grade students understand the concept of addition using visual aids. Students will look at pictures with different groups of items and count them. They will then write down the number that corresponds to each group. Next, they will learn to connect these numbers using a plus sign to signify addition and an equal sign to show the result. The goal is to find the total sum without exceeding 10. This exercise will reinforce their counting skills and introduce them to basic addition. For the class activity, provide various pictures with different items and ask students to practice writing addition sentences. Encourage them to explain their thought process and verify their answers with peers or the teacher.

Example Time: Adding Fruits Together! – Counting apples and oranges – Writing the addition sentence – We use ‘+’ to show adding and ‘=’ for the result – 4 apples plus 3 oranges equals what? – Add the number of apples to the number of oranges – Let’s find the sum together – Count all the fruits to see how many we have in total | This slide is designed to visually demonstrate the concept of addition to first-grade students using familiar items like fruits. Start by showing pictures of 4 apples and 3 oranges. Explain that addition is simply combining two groups of items to find out how many there are altogether. Write the addition sentence on the board as 4 + 3 = ?, and then count all the fruits together with the class to find the sum. Make sure to involve the students in the counting process to reinforce the concept. The goal is for students to understand that addition is combining groups and that the sum is the total amount. Encourage students to use their fingers or objects to count if needed.

Your Turn to Try: Writing Addition Sentences – Count objects in your picture – Write an addition sentence – For example, if you see 4 apples and 6 oranges, write 4 + 6 = 10 – Sentence sums up to 10 – Share your sentence with the class | This slide is an interactive activity for students to apply their understanding of addition by writing sentences that sum up to 10. Encourage students to carefully count the objects in the pictures provided to them. Once they have the total count, they should write an addition sentence that equals the sum of the objects, ensuring that the total does not exceed 10. For example, if there are 3 stars and 5 hearts in the picture, they would write ‘3 + 5 = 8’. After writing their sentences, ask students to share their answers with the class. This will help reinforce their learning and allow them to see different combinations that add up to 10. Provide guidance and positive feedback as they work through this exercise.

Class Activity: Addition Art – Create an art project with items – Count items and write addition sentences – If you have 3 stars and 4 hearts, write: 3 + 4 = 7 – Share your art and addition sentences – Enjoy learning addition with art! | This activity is designed to combine creativity with mathematical concepts. Students will use various items to create an art piece. They will then count the number of each type of item used and write addition sentences that sum up to 10 or less. For example, if a student uses 3 stars and 4 hearts in their art, they would write the addition sentence ‘3 + 4 = 7’. After completing their art, students will present their project and explain their addition sentences to the class. This will help them understand addition in a fun, interactive way. For the teacher: Prepare different craft items for students to choose from. Ensure each student has enough items to create simple addition problems. Walk around the classroom to assist and encourage students as they work on their projects. Have a sharing session at the end where students can proudly display their art and explain their addition sentences.

Review and Goodbye! – Recap on addition concepts – Addition combines two numbers into a larger one. – Writing addition sentences – Use pictures to form sentences like 3 apples + 2 apples = 5 apples. – Praise for hard work – Looking forward to next class | As we conclude today’s lesson, it’s important to review the key concepts we’ve learned. Start by asking the students what addition is and how it helps us combine numbers. Reinforce the idea that addition is putting together and adding up to find out ‘how many in total’. Then, review how to write an addition sentence using examples from today’s lesson, such as combining different sets of objects and writing the corresponding addition sentence. Acknowledge the students’ efforts and progress in understanding addition, and express excitement for the next class where they will continue to build on these foundational math skills.
