Answer to Question #124743 in Algebra for Sphesihle Zuma

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:

an = dn - c

The an stands for the nth term of the pattern. So a1 is the first term and a2 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.
