Question #124743

Evaluate the use of matches to build patterns, keeping in mind the cognitive stage that grade 6 learners have reasonably reached and the progression from teaching concepts in concrete, semi - concrete and semi - abstract ways. Write down your thoughts on this.

Expert's answer

the use of matches to build patterns

we have to find matching pattern by this rule:

*a*_{n}* = dn - c*

The *a*_{n} stands for the *n*th term of the pattern. So *a*_{1} is the first term and *a*_{2} is the second term of the pattern. The *d* is the difference between each of the terms. The *n* stands for the term you're calculating. If you're calculating the third term, then *n* is 3. And *c* is a constant that you'll need to calculate.

concept of concreate:

**concrete** is **defined** as the minimum strength the **concrete** must posses after 28 days of construction with proper quality control. **Grade** of **concrete** is denoted by prefixing M to the desired strength in MPa

concept of semi-concrete:

The math **concept**/skill is next modeled at the representational (**semi**-**concrete**) level, which involves drawing pictures that represent the **concrete** objects previously used

concept of semi-abstract:

pertaining to or designating a style of painting or sculpture in which the subject remains recognizable although the forms are highly stylized in a manner derived from **abstract** art

these terms concrete,semi-concrete,and semi-abstract are helping to matching in build patterns.
