Addition Strategies

Tuesday we explored addition strategies! I gave all the students the same addition problem, and let them solve the problem however they wanted. I selected several students to write their strategies on the board. The kiddos were shocked at how many different ways their friends solved the same problem! We focused on four different strategies to add to our journal: Number line, Adding on by Place Value, Adding by Place Value, and Vertical Addition. Both the place value strategies are similar, but one continues on in one equation, while the other is broken into separate equations.

It's important the kids know different ways to solve problems. First, it helps them move to the most efficient way possible. Second, it assists in their checking of the problems. Super important!!
