Cut a pizza into 2 equal parts: each part is 1/2. Learn the numerator and denominator, then 1/4 and 3/4 — and why the parts must be equal.
The videos are narrated in Mandarin Chinese with on-screen subtitles.
📚 What you will learn
- Cut something into 2 equal parts: each part is one half (1/2).
- The bottom number is the denominator: how many equal parts.
- The top number is the numerator: how many parts we take.
- Cut into 4 equal parts: one part is 1/4, three parts are 3/4.
- The parts must be equal, otherwise it is not a fraction of the whole.
🎙️ What the video says (in Chinese)
- 把一个披萨平均分给两个人，每人分到多少？我们来认识分数！
- 把披萨平均分成 2 份，每份是它的二分之一。
- 下面的 2 叫分母，表示平均分成 2 份；上面的 1 叫分子，表示取了其中 1 份。
- 平均分成 4 份，每份是四分之一。取 3 份，就是四分之三。
- 记住：一定要平均分，才能用分数表示！

With 10 plates, multiplication wins by a mile.Watch →🎬 The 9 Times Table Finger TrickHold up ten fingers and fold down the 3rd: 2 fingers on the left, 7 on the right, so 9 × 3 = 27. Works all the way from 9 × 1 to 9 × 9.Watch →🎬 Why Is the Remainder Smaller Than the Divisor?Make squares from 13 sticks, 4 sticks each: 3 squares and 1 left over, so 13 ÷ 4 = 3 R 1. If 4 were left, you could make one more square!Watch →🎬 Hours and MinutesThe minute hand moves 1 minute per small mark and 5 minutes per big mark. Hour hand just past 8, minute hand on 3: 8:15.Watch →🎬 Sharing Equally: What Division MeansShare 12 peaches among 3 monkeys, one round at a time. Each gets 4: that is sharing equally, written 12 ÷ 3 = 4.Watch →🎬 Measuring with a RulerLine one end up with 0 and read where the other end points: 6 cm. If you start at 2 and end at 8, subtract: 8 − 2 = 6 cm. And 1 m = 100 cm.Watch →🎬 Times As Many2 red flowers and 6 yellow ones: circle the yellow flowers in twos and you get 3 groups, so there are 3 times as many. Then 6 ÷ 2 = 3.Watch →🎬 Area of a RectangleCover a 4 cm × 3 cm rectangle with 1 cm² squares: 4 in a row, 3 rows, 12 squares. So area = length × width = 4 × 3 = 12 cm².Watch →🎬 Long and Short Months: The Knuckle TrickMake a fist and count across your knuckles: knuckles are 31-day months, the dips between them are 30-day months. February is special: 28 or 29 days.Watch →🎬 How to Use a ProtractorTwo things must line up: the centre on the vertex and the zero line on one side. Then read from the zero you started on: 60°, not 120°.Watch →🎬 Parallel and Perpendicular LinesTwo lines on a flat surface that never meet are parallel; lines that cross at a right angle are perpendicular, meeting at the foot of the perpendicular.Watch →🎬 The Pancake ProblemA pan holds 2 pancakes and each side takes 3 minutes. Never leave a space empty and 3 pancakes take 3 rounds, 9 minutes, instead of 12.Watch →🎬 Reading Big NumbersSplit the number into groups of four from the right: the wan group and the ones group. 30070500 is read 三千零七万零五百.Watch →🎬 Chickens and Rabbits in a Cage8 heads, 26 legs. Ask every animal to lift two legs: 10 legs are left, all rabbit legs, 2 per rabbit. So 5 rabbits and 3 chickens.Watch →🎬 Angles of a Triangle Add Up to 180°Tear off the three corners of a triangle and put them together: they make a straight angle. So the angles of any triangle add up to 180°.Watch →🎬 The Distributive LawA rectangle (4 + 6) long and 3 wide splits into 4 × 3 and 6 × 3, so (4 + 6) × 3 = 4 × 3 + 6 × 3. In general (a + b) × c = a × c + b × c.Watch →🎬 What Decimals MeanSplit a square into 10 equal parts: one part is 1/10 = 0.1.
