With the advent of Common Core came the further full-court press of progressive mathematics. For years now, as Common Core math has been pushed upon the American public public, parents and kids alike have banged their heads on their desks and dinner tables across the country, trying desperately to make sense of convoluted and drawn-out mathematics problems parents never had to conquer when they were in school.

A recent article from the Hechingerreport,

## Back off parents: It’s not your job to teach Common Core math when helping with homework

made me so mad my head almost exploded. Seriously, that’s just the craziest nonsense ever. The whole idea of the article was essentially, “parents don’t help your own children with their math, because you can’t understand it anyway. Just make sure the work gets done, no matter what”.

How is this not the school and a subject – math – getting right in the middle between kid and parent, essentially making the kid think the parent is stupid, pulling them – and the family – apart?

For years, I’ve tried to help parents understand the differences between progressive and traditional math because there really is no way to fight progressive math if you don’t know what is wrong with it and what is better. It wasn’t until I saw this article that I realized I didn’t have to invent the wheel.

Ten Myths About Math is written by a number of really excellent math educators who have taken the time to write out each math myth and explain fully why it simply isn’t true. Please visit the article to print out the article, but I’m going to paste the myths and explanations in below so you can read them immediately.

### Myth #1

*Only what students discover for themselves is truly learned.*

REALITY

Students learn in a variety of ways. Basing most learning on student discovery is time-consuming, does not insure that students end up learning the right concepts, and can delay or prevent progression to the next level. Successful programs use discovery for only a few very carefully selected topics, never all topics.

### Myth #2

*Children develop a deeper understanding of mathematics and a greater sense of ownership when they are expected to invent and use their own methods for performing the basic arithmetical operations, rather than study, understand and practice the standard algorithms.*

REALITY

Children who do not master the standard algorithms begin to have problems as early as algebra I.

The snubbing or outright omission of the long division algorithm by NCTM- based curricula can be singularly responsible for the mathematical demise of its students. Long division is a pre-skill that all students must master to automaticity for algebra (polynomial long division), pre-calculus (finding roots and asymptotes), and calculus (e.g., integration of rational functions and Laplace transforms.) Its demand for estimation and computation skills during the procedure develops number sense and facility with the decimal system of notation as no other single arithmetic operation affords.

From 1998 issue of the Notices of the American Mathematical Society:

*“We would like to emphasize that the standard algorithms of arithmetic are more than just ‘ways to get the answer’ — that is, they have theoretical as well as practical significance. For one thing, all the algorithms of arithmetic are preparatory for algebra, since there are (again, not by accident, but by virtue of the construction of the decimal system) strong analogies between arithmetic of ordinary numbers and arithmetic of polynomials.”* (The above was quoted in an open letter to Secretary of Education Richard Riley in 1999, which was signed by 200 prominent U.S. mathematicians.)

### Myth #3

*There are two separate and distinct ways to teach mathematics. The NCTM backed approach deepens conceptual understanding through a problem solving approach. The other teaches only arithmetic skills through drill and kill. Children don’t need to spend long hours practicing and reviewing basic arithmetical operations. It’s the concept that’s important.*

REALITY

“The starting point for the development of children’s creativity and skills should be established concepts and algorithms… Success in mathematics needs to be grounded in well-learned algorithms as well as understanding of the concepts.”

What is taught in math is the most critical component of teaching math. How math is taught is important as well, but is dictated by the “what”. Much of understanding comes from mastery of basic skills – an approach backed by most professors of mathematics. It succeeds through systematically empowering children with the pre-skills they need to succeed in all areas of mathematics. The myth of conceptual understanding versus skills is essentially a false choice – a bogus dichotomy. The NCTM standards suggested “less emphasis” on topics needed for higher math, such as many basic skills of arithmetic and algebra.

“That students will only remember what they have extensively practiced – and that they will only remember for the long term that which they have practiced in a sustained way over many years – are realities that can’t be bypassed.”

### Myth #4

*The math programs based on NCTM standards are better for children with learning disabilities than other approaches.*

REALITY

“Educators must resist the temptation to adopt the latest math movement, reform, or fad when data-based support is lacking…”

Large-scale data from California and foreign countries show that children with learning disabilities do much better in more structured learning environments.

### Myth #5

*Urban teachers like using math programs based on NCTM standards.*

REALITY

“Mere mention of [TERC] was enough to bring a collective groan from more than 100 Boston Teacher Union representatives…”

### Myth #6

*“Calculator use has been shown to enhance cognitive gains in areas that include number sense, conceptual development, and visualization. Such gains can empower and motivate all teachers and students to engage in richer problem-solving activities.” (NCTM Position Statement)*

REALITY

Children in almost all of the highest scoring countries in the Third International Mathematics and Science Survey (TIMMS) do not use calculators as part of mathematics instruction before grade 6.

A study of calculator usage among calculus students at Johns Hopkins University found a strong correlation between calculator usage in earlier grades and poorer performance in calculus.

### Myth #7

*The reason other countries do better on international math tests like TIMSS and PISA is that those countries select test takers only from a group of the top performers.*

REALITY

On NPR’s “Talk of the Nation” program on education in the U.S. (Feb. 15, 2005), Grover Whitehurst, Director of the Institute of Education Sciences at the Department of Education, stated that test takers are selected randomly in all countries and not selected from the top performers.

### Myth #8

*Math concepts are best understood and mastered when presented “in context”; in that way, the underlying math concept will follow automatically.*

REALITY

Applications are important and story problems make good motivators, but understanding should come from building the math for universal application. When story problems take center stage, the math it leads to is often not practiced or applied widely enough for students to learn how to apply the concept to other problems.

“[S]olutions of problems … need to be rounded off with a mathematical discus-sion of the underlying mathematics. If new tools are fashioned to solve a problem, then these tools have to be put in the proper mathematical perspec-tive. … Otherwise the curriculum lacks mathematical cohesion.”

### Myth #9

*NCTM math reform reflects the programs and practices in higher performing nations.*

REALITY

A recent study commissioned by the U.S.Department of Education, comparing Singapore’s math program and texts with U.S. math texts, found that Singapore’s approach is distinctly different from NCTM math “reforms.”

Also, a paper that reviews videotaped math classes in Japan shows that there is teacher-guided instruction (including a wide variety of hints and helps from teachers while students are working on or presenting solutions).

### Myth #10

*Research shows NCTM programs are effective.*

REALITY

There is no conclusive evidence of the efficacy of any math instructional program.

Increases in test scores may reflect increased tutoring, enrollment in learning centers, or teachers who supplement with texts and other materials of their own choosing. Also, much of the “research” touted by some of the NSF programs has been conducted by the same companies selling the programs. State exams are increasingly being revised to address state math standards that reflect NCTM guidelines rather than the content recommended by mathematicians.

The state tests in Maryland have a number of 3 point problems in which students are awarded 1 point for performing the math correctly and 2 points for explaining it. It is thus possible to do the math right but get half the credit that another student gets with the wrong answer.
