Addition is one of the basic mathematical operations that students learn in the early grades. Once they have a solid understanding of numbers and counting, they are introduced to addition as a way to combine two or more numbers to get a total. As students progress through their academic journey, they’ll need to work on mastering different strategies to solve addition problems.
In this article, we’ll explore activities that teachers can use to teach students how to complete addition sentences that sum up to 20. These activities will help students use different strategies to solve the problems and develop their mental math skills.
1. Addition War Game
Addition war is a fun and exciting game that helps students practice their addition skills. The game requires two players and a deck of cards. In this game, each player gets half of the deck of cards, and they take turns flipping over the top card from their pile. After each player has flipped over a card, they add the two numbers together. If the sum is 20 or less, the player with the highest sum wins the round and takes both cards. Play continues until one player has all of the cards or until a set number of rounds have been played.
2. Number Bonds Worksheets
Number bonds are a pictorial representation of numbers that show how they can be broken down into smaller parts. In the case of addition, number bonds show how two numbers are combined to make a third number. Number bond worksheets provide students with a visual way to understand the addition sentence and solve the problems.
3. Addition with Manipulatives
Manipulatives are physical objects that students can use to represent numbers and visualize the addition process. For example, students can use blocks, beads, or counters to represent different numbers. By physically manipulating the objects, students can see how two numbers are combined to make a sum. This makes addition more concrete and helps students develop a deeper understanding of the concept.
4. Addition Bingo
Like the classic game Bingo, Addition Bingo is a fun and exciting game that students can play to practice their addition skills. In this game, the teacher creates Bingo boards with different addition problems that sum up to 20. As the teacher calls out a problem, students mark the answer on their Bingo board. The first student to complete a line, column, or diagonal of answers wins the game.
5. Addition Bathtub
Addition Bathtub is an interactive game that requires a bathtub cut-out, water droplet cut-outs, and number cut-outs. The bathtub is labeled with the numbers 0-20, and the students must find two numbers that make the sum of 20. They then place the water droplet cut-out on the bathtub and the two number cut-outs in the right position. This game helps students understand the concept of adding two numbers to make a sum of 20.
By using these activities, teachers can help students develop a deeper understanding of addition and how to complete addition sentences that sum up to 20. Whether using manipulatives, Bingo games or number bond worksheets, these activities will give students the foundation they need to excel in math throughout their academic journey.
