Interview with a Middle School Math Teacher
L.B. is a 6th grade math teacher who uses an inquiry-based method called CPM.
What is CPM?
Before CPM was adopted, the district was using a 14-year old book because they had didn't have any funding. She said she rarely used the book. During her 4th year of teaching the school district adopted CPM. CPM stands for College Preparatory Math. There were 6 full days of training on how to use the book and do group strategies. She said it was “amazing.” The training even changed the way she structured some of her other classes. She refers to CPM as spiraling. Spiraling means that when a concept is introduced it is revisited again and again throughout the year. She says this is very important.
The same year it was adopted, it was overturned because the parents wanted traditional math. The parents said that there was “too much group work and they didn't want their child to have to sit with people who didn't speak English.” The parents also found it difficult to help their students with homework because there wasn't a book with examples. The parents went to the board and the board overturned CPM. The board spent another $500,000.00 and bought Holt instead (Holt is a very traditional approach to teaching math). Because the district had already paid for CPM they allowed CPM to be used as a supplement, but Holt was the main book.
This year, L.B. is using straight CPM this year because she believes it is best practices.
How does CPM align with Common Core and NCTM?
“It is totally aligned” she explained. There is a new version that has been revised so that EVERY lesson meets grade-level common core. CPM's philosophy cares more about teaching it well then they do about their own curriculum. She thinks they are non-profit.
Addressing the basics: How do you get students who aren't at grade level caught up?
CPM doesn't address this. L.B. often questions the importance of being able to do things like multiplication in your head. Calculators are in EVERYTHING! Still, she believes students should be able to do basic math in their head. When students are really impacted she calls the parents/talks to them during conferences and asks them to do flashcards with their students.
Homework
Homework is important because students need extra practice. CPM believes that if a student doesn't get it, why not give them another chance. Homework isn't graded. If you do it, you get full credit because you can always retry it and do it later. “Why take off points if they just don't get it yet?” L.B. explains that about 90% of students complete homework in CPM. It works. There's homework help online that gives them step-by-step clues.
Collaboration
Students work in groups of 4. CPM uses “heterogeneous groups.” To achieve this, L.B. designs the groups so that there are 2 students with high OAKS math scores, and 2 students with low OAKS math scores. Students are assigned roles. Students are either the resource manager, facilitator, recorder/reporter, or task manager.
Assessment
L.B. gives pretests when she knows the concept is brand new to the students. She gives quizzes every couple of weeks. At the end of the chapter she gives a test.
