A set of four posters showing different addition strategies.
Hang this set of posters in the classroom when teaching students how to add double-digit numbers using different strategies.
The strategies include:
Jump Strategy: The jump strategy is when you use a number line to jump in tens and ones to arrive at the answer.
Split Strategy (two versions): The split strategy is when you split a number into parts and add each part separately. This is useful for large numbers.
Compensation Strategy: The compensation strategy is when you round numbers in an equation to make it easier to solve in your head.
