Welcome to Addition: Adding 10 – Greet the day with math fun! – Today’s goal: Learn to add 10 – Discover ten-friends for numbers – If we have 5, its ten-friend is 15 because 5 + 10 = 15 – Practice makes perfect – We’ll do activities to help us learn | Begin the class with an enthusiastic greeting to set a positive tone for the lesson. Introduce the concept of adding 10 as a fundamental skill in math, framing it as a fun activity. Explain ‘ten-friends’ as a way to make the concept more relatable and easier to grasp for first graders; for example, the number 5’s ten-friend is 15 because when you add 10 to 5, you get 15. Use visual aids and physical objects like counting blocks or drawings to illustrate this concept. Plan engaging activities such as number line jumps or adding 10 to different numbers with interactive games. Ensure to provide plenty of practice opportunities and encourage students to explain their thought process to reinforce their understanding.

Understanding Addition: Adding 10 – What is addition? – Addition is combining numbers to make a new total – Adding numbers makes them bigger – Imagine adding apples to a basket – If you have 3 apples and add 7 more, you now have 10 apples! – Adding 10 to any number – When we add 10, it’s like getting 10 more apples all at once | This slide introduces the concept of addition to first graders by relating it to a tangible experience like adding apples to a basket. Start by explaining that addition is the process of combining two or more numbers to get a new total. Use simple, relatable examples to illustrate this point, such as adding a certain number of apples to those already in a basket to find out how many apples there are now. Emphasize that when we add 10 to any number, it’s like getting a whole new set of 10 apples at once, which makes the number much bigger. Encourage the students to visualize the process and use their fingers or objects to practice adding 10 to different numbers up to 20.

Adding 10 to Numbers – Jump forward 10 on number line – Example: 1 + 10 – Starting at 1, count up 10 spaces – We land on number 11 – The number after 10 jumps is 11 – So, 1 + 10 equals 11 | This slide introduces the concept of adding 10 to a number using a number line, which is a visual tool that helps students understand the addition process. Start by explaining that adding 10 means jumping forward 10 spaces on the number line. Use the example of 1 + 10 to show this visually. You can use a physical number line in the classroom or draw one on the board. Have the students start at 1 and count forward 10 spaces. They will see that they land on 11, demonstrating that 1 + 10 equals 11. Reinforce this concept by having students practice with other numbers, always adding 10. This hands-on activity will help solidify their understanding of the addition of 10.

Practice Time: Adding 10! – Let’s practice adding 10 – Start with 5, add 10, get 15 – Example: 5 + 10 is like 5 fingers plus 10 fingers – Your turn: 3 + 10 equals? – Use your fingers or counters to add 10 to 3 – Share your answers with the class | This slide is designed for an interactive class activity where students practice adding 10 to different numbers. Start by demonstrating with the number 5, showing that adding 10 results in 15. This can be visualized by counting on fingers or using counters. Then, prompt the students to try the same with the number 3, encouraging them to use physical objects or their fingers to count. After they have tried, ask them to share their answers to ensure understanding. The goal is to reinforce the concept of addition by 10 in a fun and engaging way. Possible activities include using blocks, drawing, or interactive games where each student adds 10 to a number they choose.

Adding 10 is Fun! – Start with 10-blocks and 1-blocks – Adding 10 means one more 10-block – If you have 1 ten-block and add another, now you have 2 ten-blocks, which is 20! – Visualize 10-blocks stacking up – Imagine building a tower, each new level is another 10-block added – Practice with different 1-blocks – Try adding 10 to numbers like 1, 2, 3, and see the new numbers you get! | This slide introduces the concept of adding 10 in a tangible way using blocks. It’s crucial to help students visualize the process of addition by stacking up 10-blocks. Each time we add 10, we’re essentially adding another layer to our ‘tower’ of blocks. Encourage the students to use physical blocks if available, or draw representations on paper. This will help them understand that adding 10 is just putting one more group of 10 to what they already have. During the activity, guide them to add 10 to single-digit numbers to reinforce the concept and make it interactive and fun.

Let’s Play a Game: Adding 10! – Roll the dice and move spaces – Add 10 to your number – If you roll a 4, move 4 spaces then add 10 to get 14 – Discover your new spot – Share with the class | This interactive game is designed to help first graders practice the concept of adding 10 in a fun and engaging way. Provide each student with a dice and a game board with numbered spaces. As they roll the dice, they will move forward that number of spaces and then add 10 to the number they land on. This activity will help them visualize the addition process and reinforce their understanding of the number sequence. Encourage students to articulate their thought process as they add 10, which will help solidify their learning. Be prepared with different scenarios for students who may need additional support or challenge. For example, if a student rolls a 6, they move 6 spaces and then add 10, landing on 16. Ask them to explain how they got to that number. This will also serve as an assessment of their comprehension of the concept.

Class Activity: Adding 10 Relay – Split into teams and line up – First person gets a number card – ‘Go!’ means add 10 and pass it on – Last person writes answer on board | This activity is designed to be a fun and interactive way for first graders to practice adding 10 to numbers up to 10. Before starting, explain to the students how to add 10 to a number. Demonstrate with a few examples, such as 5 + 10 = 15, and ensure they understand the concept. Then, organize the class into small teams and have them line up. Give the first person in each line a card with a number on it. When you say ‘Go!’, the first person adds 10 to their number, tells the next person in line the new number, and this continues until the last person in line writes the final answer on the board. Possible variations of the activity could include using a dice to determine the starting number, having students draw the number and the +10 on a mini whiteboard before passing it on, or timing each team to add a competitive element.

Review Time: Adding 10 – Recap: What is adding 10? – We learned that adding 10 to a number gives us a bigger number. – Example: Adding 10 to 7 – Who can demonstrate what 7 + 10 is? – Adding 10 grows our number – Our number jumps up to the next ten! – Practice makes perfect! | This slide is meant to consolidate the day’s learning about adding 10 to numbers up to 20. Start by asking the class to recall the main points of the lesson. Then, invite a volunteer to come up and add 10 to the number 7 on the board, reinforcing the concept that adding 10 increases the original number by one ten. Emphasize that when we add 10, the number gets larger and we move to the next group of ten. Encourage the students to practice this concept with different numbers to gain confidence and proficiency in this foundational math skill.

Homework Challenge: Adding 10 – Take home your adding 10 worksheet – Solve each problem carefully – Show your work with tools – Use number lines or 10-blocks to add – We’ll review them together tomorrow | This homework is designed to reinforce the concept of adding 10, which we’ve learned in class. Encourage the students to attempt every problem and remind them that it’s okay to make mistakes; the goal is to learn and improve. Emphasize the importance of showing their work using number lines or 10-blocks, as this visual representation helps solidify their understanding of addition. During the next class, plan to review the worksheet as a group, allowing students to discuss the strategies they used and to learn from each other. Prepare to offer praise for effort and correct answers, and be ready to provide additional support where needed.
