Day 2 Math: Ratios (比率)

📐 Day 2 Math: Ratios (比率)

🎧 Listen to the Lesson (听讲解)

Hello, Sisi! Today we’re learning about Ratios（比率）. Ratios are very important in PSLE Math!

📚 Key Vocabulary (重点词汇)

Ratio 比率
Simplify 化简
Equivalent 等价的
Ratio unit 比率单位
Total 总和
Difference 差值
Remain 剩余
Change 变化

🔹 Part 1: What is a Ratio? (什么是比率？)

A ratio（比率） compares two or more quantities. We write it using a colon :.

For example: If there are 3 boys（3个男孩） and 5 girls（5个女孩） in a class:

  • The ratio of boys to girls is 3 : 5
  • Total students = 3 + 5 = 8

📌 Key Rule (关键规则)

✅ Always simplify ratios to their simplest form（最简形式）.

Example: 6 : 8 = 3 : 4 (divide both by 2)

🎮 Interactive Demo: See Ratios! (比率可视化)

Boys (男孩)

Girls (女孩)




🔹 Part 2: Simplifying Ratios (化简比率)

To simplify（化简） a ratio, divide both sides by their highest common factor (HCF)（最大公约数）.

💡 Example 1 (例题1)

Q: Simplify the ratio 12 : 18

A:

  • HCF of 12 and 18 = 6
  • 12 ÷ 6 = 2, 18 ÷ 6 = 3
  • Simplified ratio = 2 : 3

💡 Example 2 (例题2)

Q: Simplify the ratio 15 : 25 : 35

A:

  • HCF of 15, 25, and 35 = 5
  • 15 ÷ 5 = 3, 25 ÷ 5 = 5, 35 ÷ 5 = 7
  • Simplified ratio = 3 : 5 : 7

🎮 Interactive Demo: Simplify This Ratio! (化简练习)




🔹 Part 3: Ratio Problems (比率应用题)

Problem Type 1: Ratio & Total (比率与总和)

💡 Example (例题)

Q: The ratio of apples to oranges is 3 : 4. There are 28 fruits in total. How many apples are there?

A:

  • Total ratio units = 3 + 4 = 7 units
  • 1 unit = 28 ÷ 7 = 4
  • Apples = 3 units = 3 × 4 = 12

Problem Type 2: Ratio Change (比率变化)

💡 Example (例题)

Q: The ratio of boys to girls in a class is 2 : 3. After 5 more boys join, the ratio becomes 3 : 4. How many girls are there?

A:

  • Boys = 2u, Girls = 3u (before)
  • After 5 boys: Boys = 2u + 5, Girls = 3u
  • New ratio: (2u + 5) : 3u = 3 : 4
  • 4(2u + 5) = 3(3u) → 8u + 20 = 9u
  • u = 20
  • Girls = 3u = 3 × 20 = 60

🔹 Part 4: Practice Questions (练习题)

Q1: Simplify the ratio 10 : 15



Q2: The ratio of red balls to blue balls is 4 : 5. There are 36 balls in total. How many red balls?



Q3: The ratio of X to Y is 2 : 5. If X = 12, what is Y?



📝 Summary (本节总结)

  • ✅ A ratio（比率） compares quantities using :
  • ✅ Always simplify（化简） ratios to simplest form
  • ✅ Use ratio units（比率单位） to solve problems
  • ✅ Total ratio units = sum of all parts

Day 2 Science: Forces & Magnets (力与磁)

🧲 Day 2 Science: Forces & Magnets (力与磁)

🎧 Listen to the Lesson (听讲解)

Hello, Sisi! Today we’re going to learn about Forces & Magnets（力与磁）. This is one of the most important topics in PSLE Science!

📚 Key Vocabulary (重点词汇)

Force 力
Push 推
Pull 拉
Friction 摩擦力
Gravity 重力
Magnet 磁铁
Magnetic field 磁场
North pole 北极
South pole 南极
Newton (N) 牛顿（力的单位）

🔹 Part 1: What is a Force? (什么是力？)

A force（力） is a push（推） or a pull（拉） acting on an object.

Forces can:

  • 🚀 Make a stationary object move（开始运动）
  • 🛑 Make a moving object stop（停止）
  • 🔄 Change the direction（改变方向） of an object
  • 📏 Change the speed（改变速度） — faster or slower
  • 🫳 Change the shape（改变形状） of an object

The unit of force is the Newton (N)（牛顿）.

🔹 Part 2: Types of Forces (力的类型)

1. Frictional Force （摩擦力） ⭐⭐⭐

Friction（摩擦力） is a force that opposes motion（阻碍运动） between two surfaces in contact.

📝 Key Point: Friction always acts in the opposite direction（相反方向） to motion.

💡 Example (例题)

Q: Why is it harder to slide a box on a rough surface than on a smooth surface?

A: Because a rough surface（粗糙表面） has more friction（更大的摩擦力） than a smooth surface. The rough surface creates more resistance against the motion of the box.

2. Gravitational Force （重力）

Gravity（重力） is the force of attraction（吸引力） between objects. On Earth, gravity pulls everything downwards（向下）.

💡 Example (例题)

Q: A ball is thrown upwards. What force causes it to come back down?

A: The gravitational force（重力） of the Earth pulls the ball back down.

🔹 Part 3: Magnets (磁铁)

A magnet（磁铁） is an object that produces a magnetic field（磁场） and attracts certain metals like iron（铁）, nickel（镍）, and cobalt（钴）.

Magnet Poles (磁极)

Every magnet has two poles（极）:

  • 🧭 North Pole (N)（北极）
  • 🧭 South Pole (S)（南极）

📌 Golden Rule of Magnets (磁铁黄金法则)

✅ Like poles REPEL（同极相斥） — N repels N, S repels S

✅ Unlike poles ATTRACT（异极相吸） — N attracts S

🎮 Interactive Demo: Magnets! (磁铁演示)

🧲 N

🧲 S

🔹 Part 4: Practice Questions (练习题)

Q1: What force pulls objects towards the Earth?



Q2: Two magnets with their North poles facing each other will:



Q3: Which surface has the MOST friction?



📝 Summary (本节总结)

  • ✅ A force（力） is a push or a pull
  • ✅ Friction（摩擦力） opposes motion
  • ✅ Gravity（重力） pulls objects downwards
  • ✅ Like poles repel（同极相斥）, unlike poles attract（异极相吸）

Day 1 Math: Mixed Fraction Operations (分数混合运算)

🧮 Day 1 Math: Mixed Fraction Operations (分数混合运算)

Hello, Sisi! Today we will learn about fraction multiplication 分数乘法 and fraction division 分数除法. This is a key topic for P6 Math and the PSLE exam!

📚 Key Vocabulary (重点词汇)

Fraction 分数
Numerator 分子
Denominator 分母
Multiply 乘
Divide 除
Reciprocal 倒数
Simplify 化简
Lowest terms 最简分数

🔹 Part 1: Fraction Multiplication (分数乘法)

To multiply fractions 乘分数, we follow a simple rule:

📌 The Rule (规则)

Multiply the numerators（分子乘分子）, then multiply the denominators（分母乘分母）.

💡 Example (例题)

Q: Calculate 2/3 × 4/5

A:

  • Numerators: 2 × 4 = 8
  • Denominators: 3 × 5 = 15
  • Answer = 8/15 (already in lowest terms)

🎮 Interactive Demo: See the Rule! (互动演示)

Click the button to watch the numbers move（移动）!

2/3 × 4/5 = ?

🔹 Part 2: Fraction Division (分数除法)

To divide fractions 除分数, we use the “flip and multiply”（颠倒相乘）method:

📌 The 3 Steps (三步法)

Step 1: Keep the first fraction as it is（保持不变）

Step 2: Change ÷ to ×, then flip the second fraction (reciprocal)（颠倒求倒数）

Step 3: Multiply as usual!（照常相乘！）

💡 Example (例题)

Q: Calculate 3/4 ÷ 2/3

A:

  • Step 1: Keep 3/4
  • Step 2: Change to × and flip → 3/4 × 3/2
  • Step 3: 3 × 3 = 9, 4 × 2 = 8
  • Answer = 9/8 = 1 1/8 (mixed number)

🎮 Interactive Demo: Flip & Multiply! (颠倒相乘演示)

3/4 ÷ 2/3 = ?

🔹 Part 3: Simplifying Answers (化简答案)

Always simplify 化简 your answer to the lowest terms 最简分数! If the numerator is bigger than the denominator, convert to a mixed number（带分数）.

📌 How to Simplify (如何化简)

Find the HCF（最大公约数）of the numerator and denominator, then divide both by it.

Example: 6/8 → HCF of 6 and 8 is 2 → 3/4 ✅

🔹 Part 4: Practice Questions (练习题)

Q1: What is 1/4 × 1/2 = ?

Q2: What is 2/3 ÷ 1/3 = ?

Q3: Simplify 4/6 = ?

📝 Summary (本节总结)

  • ✅ Multiply: Numerator × Numerator, Denominator × Denominator（分子乘分子，分母乘分母）
  • ✅ Divide: Keep, Flip, Multiply（保持，颠倒，相乘）
  • ✅ Always simplify（化简） to lowest terms
  • ✅ Convert to mixed number（带分数） if numerator > denominator
