MATH 2023I

Mathematical representation refers to the ability to

• Solve mathematical equations directly.

• Present mathematical ideas or concepts in various forms.

• Read data tables without understanding their context.

• Memorize formulas without application in a specific context.

An example of mathematical representation is

• Using diagrams or graphs to explain relationships between variables.

• Writing an essay about the applications of mathematics.

• Memorizing definitions of variables and coefficients.

• Copying calculation results without analysis.

In a survey, 50% of students prefer to learn using videos, 30% use books, and the rest use interactive apps. The best representation for this data is

• Pie chart.

• Histogram.

• Data table.

• Line chart.

Which of the following statements represents mathematical representation in verbal form?

• Population growth graph.
  

• The formula y=mx+cy=mx+c.

• A written explanation of patterns in an arithmetic sequence.

• Bar diagram.

The table below shows harvest results (in tons) over five years. The most suitable representation for analyzing trends is

• Line graph.

• Pie chart.

• Frequency table.

• Pictogram.

Mathematical communication can be done in the following forms

• Visual, symbolic, and verbal.

• Oral and memorization.

• Diagrams without explanations.

• Statements without context.

An example of good mathematical communication is

• Using equations without explaining the variables.

• Connecting the results of calculations with the context of the problem.

• Copying formulas from textbooks.

• Answering questions without providing reasoning.

Which statement demonstrates mathematical communication skills?

• "This data shows a linear relationship."

• "I got this result, but I don’t know why."

• "I only made this graph because I was asked to."

• "The answer is 25, period."

A student explains the solution to a problem using diagrams, tables, and written descriptions. This demonstrates

• Mathematical representation and communication skills.

• Science literacy.

• Problem-solving skills only.

• Basic arithmetic.

When writing a report on the results of an experiment, the section that demonstrates mathematical communication is

• Explaining the relationship between variables using a graph.

• Writing the experimental procedure.

• Writing the initial hypothesis.

• Listing tools and materials.
