Learning our Addition strategies

In Math, the students have been learning their Power of Ten addition strategies since the beginning of the school year. The Power of Ten is a way of thinking about Math that encourages students to make as many 10's as they can when adding (because it's so much easier to work with them). So far, we've worked with strategies to make 10's when adding 9, 8, and 5, as well as making sure they know their 'Friendly Number' facts (any two numbers added together that make 10: 1+9, 2+8, 3+7, etc.). The students were surprised to learn that they've already learned strategies that allow them to successfully solve more than half of their basic facts (addition facts from 0+1 to 9+9)! Today, we started working on the next strategies - doubles, doubles +1, and doubles -1. Here's a sample of their work from today:
