Hbmt3303 teaching mathematics in form one
The document provides an introduction to fractions. It defines a fraction as the ratio of two whole numbers, with the top number called the numerator and the bottom number called the denominator. It explains that a fraction is proper if the numerator is smaller than the denominator, and improper if the numerator is equal to or larger than the denominator. It also discusses equivalent fractions and how two fractions are equivalent if you can find a whole number that divides the numerator and denominator of one fraction to give the other fraction.
Ļ
Pi is an irrational number represented by the Greek letter Ļ that is the ratio of a circle's circumference to its diameter. It has infinite non-repeating digits and is used to calculate the circumference and area of circles, cylinders, and spheres. Some argue the constant tau, which is equal to 2Ļ, should replace pi in formulas since many equations involve 2Ļ. Pi has been calculated to over 10 trillion digits and almost became legally defined as 3.2 in the late 19th century.

Pair-a-dice
Muhammad and Ally are playing a dice game where they each roll a pair of dice. The document lists Muhammad's possible rolls which give him 15 ways to win, while Ally has 18 possible ways to win. It is determined that the game is unfair because Ally has more chances to win than Muhammad.
Assessment measurement
Measurement involves determining various properties such as length, weight, temperature, and time using specific tools. It is used daily to quantify things in our environment. There are different systems of measurement like the metric system which uses units like meters, centimeters, and liters. Tools like rulers, tapes, thermometers, scales, and clocks are commonly used to measure length, temperature, weight, and time. Units can be converted between systems by relating similar units, such as 1 liter equaling 1 kilogram or 1 yard equaling 91 centimeters. The properties measured depend on the material, with things like textiles often measured by weight in grams or kilograms while rocks may be characterized by their hardness.
Measurement
The document discusses different systems of measurement including the metric system, time, and numbers. It explains common metric units like kilo, deci, and centi. Time is described as a man-made system that organizes life, with seconds, minutes, hours, days, weeks used to track and schedule time. Numbers are presented as another fundamental man-made measurement tool essential for tasks like math, timekeeping, and money. Without established systems of measurement, quantifying attributes and events would be extremely difficult.
