College instructors rate the Mathematical Practices as being of higher value for students to master in order to succeed in their courses than any of the CCSS content standards.

If a student becomes proficient at the SMPs, he/she can learn any content.

To change students’ ways of thinking, we must first change how we teach.

We need to ask ourselves . . .in my math class, who is doing the talking? Who is doing the math?

The value of the common core is only as good as the implementation of the mathematical practices.

Once you show them how, you cannot find out how they are thinking.

When a child makes a mistake, they are showing a way of thinking that needs to be addressed to the whole class. https://www.teachingchannel.org/videos/class-warm-up-routine

When you’re planning, think about “what task can I give to build understanding, rather than how can I explain clearly so they will understand.”

Going to the Zoo

32 children and 4 teachers are taking a mini-bus to the San Diego Zoo. The teachers will sit 2 to a seat and the students will have to sit either 2 or 3 to a seat. The bus has 16 seats. How many children will have to sit two to a seat, and how many children will have to sit three to a seat?

Solving It Algebraically

x = # of seats of students sitting 2 to a seaty = # of seats of students sitting 3 to a seat

x + y = 14

2x + 3y = 32

Explain flawed logic of others

Pablo solved a multiplication problem using two different methods. He made a mistake in either Method W or Method Z.

Identify the method where Pablo made a mistake and explain what he should do to correct it.

SMP #3A teacher gave her students the following problem to solve:

A farmer sold 434 pumpkins and 226 squash. How many pumpkins and squash did he sell?

Sylvia said the answer is 660 and Caleb said the answer is 208.

Which student is correct?

Explain how you know.
