Base Ten Strategy
Using base tens is a great visual to see how numbers are combined and to view what is actually happening in addition. This strategy is typically used when building to other strategies, such as the formal algorithm. Since this strategy takes some time to draw out, many students like to move away from this approach to more efficient strategies as the numbers they work with get larger.
Place Value Addition
Place Value Addition
Place value addition is a strategy that is popular in many European countries like Scotland and England. It requires you to understand place value and it is helpful to know your basic facts to 20. Many students like to use this strategy because they can easily do it in their head. However, when working with numbers of different digits, a 2-digit number plus a 3-digit number, students have to be careful. Also, the larger the numbers, the more difficult and less efficient this strategy becomes.
