## Reflection: Connection to Prior Knowledge Dividing by 1000s, Powers of 10s (Day 3) - Section 2: Math Blast - Lesson Activator

Towards the end of a unit is the time to start to introduce new concepts that will be coming up in the next unit. I love to do this Math Blast - get student thinking started.

It is also a good time to start to take those old things out. You will be able to tell which problems they are getting bored with by how much talking goes on while working. When I launch new ideas the room goes silent. (Well, OK they might groan!)

Keep it fresh. This is also great place to teach ideas that you know will be on state tests but you don't teach it till late. I love doing this, it isn't cheating it is preparing them!
