Quantitative Reasoning - JSS2 Mathematics Lesson Note

Quantitative reasoning involves making sense of numbers and using them to solve problems or make decisions. It often includes:

Example 1: Comparing and interpreting data:

Suppose you have data on the average monthly temperatures of two cities over a year: City A has an average of 25.6°C, and City B has an average of 23.4°C. Quantitative reasoning would involve analyzing these numbers to draw conclusions about which city is warmer on average.

Example 2: Using mathematical models:

If you are given a linear equation 

𝑦=2𝑥+3, quantitative reasoning would involve using this equation to predict 𝑦 values for different 𝑥 values or to analyze relationships between 𝑥 and 𝑦.

Quantitative reasoning also includes skills like estimation, data analysis, and problem-solving using numerical information.
