Hey {{custom.firstName}},

 

A quick thought as you head into Combining Exponents. It’s often very challenging to convince students that they have useful mathematical ideas to offer each other—that all of us are smarter than any one of us.

 

But when students adopt that idea, lots of classroom challenges become easier. Students participate more eagerly. They turn to one another as a resource instead of relying on your limited time and energy exclusively.

So I encourage you to snapshot several student answers on the lesson synthesis and ask students to name a response that was particularly helpful. That’s the kind of move that can support the development of a student’s mathematical idea, along with the community of a class.

Great advice from other teachers.

Be prepared for the bases to change in the card sort! Not all students will see how 10's can be made from regrouping the 2s and 5s.

Pause before slide 3 and go over multiplying unlike bases with the same exponent. Then go into the card sort. I would also talk about slide 4 as a class so students understand a power to a power before having to use that understanding in the future slides.
