Learning addition within 20 can be a fun and engaging experience for young students. Practicing addition facts within this range helps build a strong foundation in math and prepares students for more complex calculations. Here are five fun ways to practice addition within 20:
1. Number Lines and Hops
Create a number line with numbers 0-20 marked on it. You can use a long piece of paper or a whiteboard for this activity. Start at a number, and then “hop” a certain number of spaces to the right. For example, start at 5 and hop 3 spaces to land on 8. Ask students to calculate the sum of the starting number and the number of hops. This activity helps students visualize the concept of addition and how numbers relate to each other.
2. Addition War Card Game
This classic card game is a great way to practice addition within 20. You will need a standard deck of cards without jokers. Shuffle the cards and deal two cards to each player. Each player adds the numbers on their cards together. The player with the highest sum wins the round. If there is a tie, players go to “war” by playing another round. The winner of the war wins all the cards played in that round. This game is a fun way to practice mental math and addition facts.
3. Base-Ten Blocks and Towers
Base-ten blocks are a great manipulative for practicing addition within 20. Start by building a tower with a certain number of blocks. For example, build a tower with 5 blocks. Then, ask students to add a certain number of blocks to the tower. For example, add 4 blocks to the tower. Ask students to count the total number of blocks in the tower. This activity helps students visualize the concept of addition and how numbers can be represented using blocks.
4. Math Scavenger Hunt
Create a math scavenger hunt with clues that involve addition within 20. Hide clues around the classroom or school with math problems written on them. For example, “If Sally has 8 pencils and she gets 4 more, how many pencils does Sally have now?” Students have to find the clues, solve the math problem, and write the answer on a piece of paper. The student who solves the most clues correctly wins.
5. Addition Bingo
Create bingo cards with numbers 0-20 in the squares. Call out math problems that involve addition within 20. For example, “3 + 5” or “2 + 9”. Students have to solve the math problem and mark the correct answer on their bingo card. The first student to get five numbers in a row wins. This activity is a fun way to practice mental math and addition facts.
