Here's the formula for calculating a z-score: z = data point − mean standard deviation. Here's the same formula written with symbols: z = x − μ σ. Here are some important facts about z-scores: A positive z-score says the data point is above average. A negative z-score says the data point is below average. A z-score close to 0. In the latest (2019) Trends in International Maths and Science Study (TIMSS), New Zealand's nine-year-olds (Year 5) ranked 40th out of 64 countries. Year 9 students' fared worse.

Mental math can help kids understand math concepts better and get to the answer faster. Mental math is a group of skills that allow people to do math “in their head” without using pencil and paper or a calculator. One of these skills is remembering math facts, like 8 × 5 = 40. Other skills include rounding numbers and estimating calculations.
