Welcome to Addition! – Learning to make numbers – Combining numbers together – Like putting together blocks to build something bigger – Using addition sentences – An addition sentence has two numbers with a plus sign – Making numbers up to 10 – We’ll practice with numbers 1 through 10 | This slide introduces first graders to the concept of addition as a means of combining numbers to create new ones. Emphasize that addition is like building, where we put parts together to make a whole. Use simple, relatable examples such as combining blocks or adding more apples to a basket. Show how an addition sentence is formed, using the ‘+’ sign to connect two numbers. Encourage students to think of addition as a fun activity, and reassure them that we’ll be practicing with small numbers they’re already familiar with, all the way up to 10. Prepare hands-on activities with physical objects like counters or drawings to help them visualize the concept.

Exploring Addition: Making New Numbers – What is addition? – Addition is combining numbers to make a new one. – Discovering the sum – The sum is the result we get after adding. – Addends: Pieces of addition – Addends are the numbers we add together. – Practice adding numbers up to 10 – Let’s add: 2+3=?, 4+1=?, 5+5=? | This slide introduces the basic concept of addition to first graders. Start by explaining that addition is like putting together pieces of a puzzle to make a new picture, except with numbers to get a new number. Clarify that the new number we get after adding is called the sum. The pieces we put together, the numbers we add, are known as addends. Use simple examples with numbers up to 10 to illustrate these points. Encourage the students to use their fingers or objects like blocks to physically combine groups, reinforcing the concept of addition. Prepare to guide them through a few practice problems and praise their efforts to build confidence.

Learning Addition Sentences – What is an addition sentence? It’s like a math story that shows adding. – Example: 2 + 3 = 5 2 apples + 3 apples makes 5 apples! – Understanding ‘+’ and ‘=’ ‘+’ means put together, ‘=’ means ‘the same as’. – Practice with different numbers Try 4 + 1, 3 + 2, or 5 + 0 and see what you get! | This slide introduces first graders to the concept of addition sentences. Start by explaining that an addition sentence is a way to show how numbers come together to make a new number. Use everyday examples like adding apples to make it relatable. Clarify the meaning of the ‘+’ sign as the action of combining numbers and the ‘=’ sign as showing that the two sides are equal. Encourage the students to practice creating their own addition sentences using small numbers up to 10, reinforcing the concept through repetition and variety.

Making the Number 5 – Explore ways to make 5 – Add 2 and 3 to make 5 – Example: 2 crayons + 3 crayons = 5 crayons – Add 4 and 1 to make 5 – Example: 4 apples + 1 apple = 5 apples – Even 5 and 0 make 5 – Example: 5 toys + 0 toys = 5 toys | This slide is aimed at helping first graders understand that there are multiple addition sentences that result in the same number. Start by explaining that the number 5 can be made by adding two smaller numbers together. Use tangible examples like crayons or apples to illustrate this concept, as it helps children visualize the addition process. Encourage the students to use objects around them to find different combinations that add up to 5. This activity will reinforce their understanding of addition and the concept that the order of numbers doesn’t affect the sum. For the class activity, have students work in pairs or small groups to come up with as many combinations as they can and share with the class.

Making the Number 10 – Many ways to make 10 – Add 5 and 5 to make 10 – Like two hands with all fingers up! – Combine 6 and 4 to get 10 – Like six crayons and four more! – Mix 7 and 3 to total 10 – Like seven cookies and three more! | This slide is aimed at helping first graders understand that there are multiple addition combinations that result in the number 10. Start by explaining that just like smaller numbers, 10 can be made by adding two numbers together. Use tangible examples like fingers, crayons, and cookies to make the concept relatable. Encourage the students to use objects or drawings to visualize these combinations. Ask the class to come up with other pairs of numbers that add up to 10, fostering a participative environment. This activity will help solidify their understanding of addition within 10 and demonstrate the concept of number bonds.

Addition Practice: Making Numbers – Start with easy addition – Example: 1 + 1 = 2 – Progress to harder sums – Example: 2 + 3 = 5 – Multiple correct answers – 2 + 2 and 1 + 3 both make 4 – Practice makes perfect | This slide is aimed at helping students understand that there are various ways to make a number using addition, and that math can be flexible and fun. Start with simple addition problems to build confidence, then gradually introduce more challenging sums. Emphasize that different combinations can add up to the same number, showing there’s more than one way to reach an answer. Encourage students to explore different possibilities and to understand that making mistakes is a part of learning. Provide plenty of practice opportunities and praise their efforts to foster a positive learning environment.

Class Activity: Number Pairs – Pair up to explore number combinations – Use number blocks to make numbers – Find all pairs that add up to 10 – Examples: 1+9, 2+8, 3+7… – Share your number pairs with the class | This activity is designed to help students understand the concept of addition by finding pairs of numbers that add up to 10. Each pair of students will receive a set of number blocks. They will use these blocks to physically manipulate and explore different combinations that sum up to 10. Encourage them to try various pairs and see how many ways they can combine the blocks to reach the total of 10. After the activity, ask the pairs to present their findings to the class, fostering a collaborative learning environment. Possible variations for different pairs could include using dice to roll numbers and find their pairs to make 10, drawing number cards from a deck, or using a ten frame to visualize the combinations.

Becoming Addition Experts! – Congratulations on learning addition! – Many ways to make a number – Like 5 can be 2+3, 1+4, or 5+0 – Practice makes perfect – You’re on your way to mastery! | This slide is a celebration of the students’ achievements in learning about addition sentences up to 10. It’s important to reinforce the concept that there are multiple combinations that can add up to the same number, which helps build their number sense. Encourage the students to continue practicing with different numbers to become confident in their addition skills. Remind them that practice is key to becoming an addition expert. You can suggest playing addition games, using flashcards, or doing simple daily exercises to keep their skills sharp. Praise their efforts and progress to boost their confidence.
